Defendant, Joseph Alvin Anderson, appeals (1) his convictions for manufacturing and attempting to manufacture methamphetamine (No. 91-2293), (2) the district court’s denial of habeas corpus relief on his conviction for possessing an unregistered silencer (No. 91-2270), and (3) the district court’s judgment revoking his probation (No. 91-2334). We affirm on all issues, except one; we vacate the district court’s judgment revoking Anderson’s probation and remand for resentencing.
I
On February 2, 1990, law enforcement officers executed a search warrant at Anderson’s home. The officers seized a number of items from Anderson’s residence, including: various quantities of methamphetamine and amphetamine in liquid-paste and powder forms, precursor chemicals, scales, laboratory equipment, counterfeit currency, explosives, and over 100 firearms — none of which were registered to Anderson, and several of which were subsequently determined to be stolen. A recipe for manufacturing methamphetamine and drug ledgers were also seized. In a shed behind Anderson’s home, the officers discovered a clandestine laboratory which appeared to be in operation; the officers saw two pots of a liquid substance heating on a hot plate. Anderson was arrested and subsequently charged in a superseding indictment with six counts: (1) manufacture of methamphetamine, in violation of 21 U.S.C. § 841(a)(1) (1988); (2) attempted manufacture of methamphetamine, in violation of 21 U.S.C. § 846 (1988); (3) using and carrying a firearm during a drug trafficking offense, in violation of 18 U.S.C. § 924(c)(1) (1988); (4) being a felon in possession of a firearm, in violation of 18 U.S.C. §§ 922(g)(1) & 924(a)(1), (2) (1988); (5) possession of an unregistered automatic weapon, in violation of 26 U.S.C. §§ 5861(d) & 5871 (1988); and, (6) possession of a firearm that had an altered serial number, in violation of 26 U.S.C. § 5861(d) & 5871 (1988). At the time of his arrest, Anderson was on federal *254 probation for the possession of an unregistered silencer. In Criminal No. H-90-108-01, Anderson was convicted by a jury on all six counts. However, the district court vacated Anderson’s conviction under Count 6.
The district court sentenced Anderson to 120 months imprisonment on Counts 1, 2, 4, and 5 to run concurrently; a mandatory 60 month sentence on Count 3 to run consecutive to the other counts; five years supervised release on Counts 1 and 2, and three years supervised release on Counts 3, 4, and 5 to run concurrently. In addition, Anderson was ordered to pay a $50.00 special assessment on each count, for a total of $250.00. Anderson’s probation for the possession of an unregistered silencer was also revoked, and he was sentenced to ten years imprisonment for possession of the silencer, with this sentence to run consecutive to the sentence imposed in Criminal No. H-90-108-01.
In this consolidated appeal, Anderson claims that:
(a) his convictions under Counts 1 and 2 violated the double jeopardy clause, because he could not be convicted of both manufacturing methamphetamine and attempting to manufacture the same;
(b) the district court erred in sentencing him for manufacturing and attempting to manufacture methamphetamine because the government failed to allege the quantity of methamphetamine in the indictment, and the district court improperly used the entire weight of a substance containing only a trace of methamphetamine.
(c) the district court improperly instructed the jury that they could find him guilty of possessing an unregistered firearm if he had component parts of a silencer; and
(d)the district court denied him his right of allocution at his probation revocation hearing.

In appeal No. 91-2293, Anderson argues that Count 2 (attempt to manufacture methamphetamine) was a lesser included offense of Count 1 (manufacture of methamphetamine), and therefore his multiple convictions and sentences on both counts violated the double jeopardy clause. In general, “attempt is an offense included in the completed crime, and, therefore, cannot support a separate sentence and conviction.”
United States v. York,
Anderson did not merely execute steps in manufacturing one batch of methamphetamine as in Forester. Rather, there was evidence that the manufacture of methamphetamine as charged in Count 1 was factually distinct from the attempt to manufacture methamphetamine as charged in Count 2. Anderson had succeeded in manufacturing one batch of methamphetamine. See Record on Appeal, No. 91-2293, vol. 14, at 13 (some quantities of methamphetamine in its final powdered form were seized from Anderson’s house). There was evidence that Anderson was attempting to manufacture a second batch of methamphetamine when the search warrant was executed, and it was this attempt that served the basis for Anderson’s conviction under Count 2 for attempting to manufacture methamphetamine. Count 2 therefore was not a lesser included offense of Count 1.
Anderson also argues that there was insufficient evidence to support his conviction under Count 2 for attempting to manufacture a second batch of methamphetamine.
2
The standard of review for judging the sufficiency of the evidence “is whether any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt.”
United States v. Hernandez-Palacios,
There was sufficient evidence that Anderson was attempting to manufacture a second batch of methamphetamine when the search warrant was executed. In a shed behind Anderson’s house, law enforcement officers discovered a makeshift laboratory, consisting of a heater mantle, 3 two pots on top of a hot plate, 4 syrup canisters, 5 a condenser, 6 a soft drink dispenser, 7 an aluminum foil bucket, 8 large glass containers, 9 canisters possibly containing lye (sodium hydroxide), 10 and fans for ventilation 11 . The DEA chemist testified that the laboratory could be used to manufacture metham *256 phetamine. See Record on Appeal, No. 91-2293, vol. 12, at 24. Furthermore, Agent Lewis testified that, based on his experience, 12 the laboratory appeared to be a laboratory for manufacturing methamphetamine. See id. vol. 10, at 3-69. Some of the law enforcement officers who executed the search warrant testified that, upon entering the shed, they noticed that the hot plate was on, see id. vol. 9, at 75, 103-04, and smelled the distinct odor of methamphetamine emanating from the two pots that were on the hot plate, see id.; id. vol. 10, 3-116, 3-129. In addition, the officers found recipes for manufacturing methamphetamine in Anderson’s house, as well as P2P, a precursor chemical used in manufacturing methamphetamine. See id. vol. 14, at 9, 18, 20. In light of the evidence, a trier of fact could have found Anderson guilty beyond a reasonable doubt of attempting to manufacture methamphetamine. We therefore hold that there was sufficient evidence to convict Anderson under Count 2 as charged.
Anderson further contends that either his conviction under Count 1 or his conviction under Count 2 should be reversed because the district court erroneously failed to instruct the jury specifically that in order to convict him under both Counts 1 and 2, it had to find two factually distinct offenses. Because Anderson did not object to the instruction before the district court, we will reverse only if the instruction constituted plain error, “i.e., if ‘considering the entire charge and evidence presented against the defendant, there is a likelihood of a grave miscarriage of justice.’ ”

In appeal No. 91-2293, Anderson also challenges the sentences imposed for his convictions under Counts 1 and 2, claiming that (1) the government failed to allege the quantity of methamphetamine seized in the indictment, and (2) the district court erred in using the total amount of a substance containing a trace of methamphetamine rather than the total amount of usable *257 methamphetamine. 13 Because Anderson was convicted under 21 U.S.C. §§ 841(a) and 846, he was subject to the penalties of 21 U.S.C. § 841(b). The district court sentenced Anderson to ten years imprisonment on each count, such terms to run concurrently, on the ground that Anderson manufactured and attempted to manufacture one kilogram or more of a substance containing a detectable amount of methamphetamine. See 21 U.S.C. § 841(b)(l)(A)(viii) (1988). 14
Anderson first argues that he should not have been sentenced based on the quantity of methamphetamine involved, because the government did not mention a specific quantity of methamphetamine in the indictment. We expressly rejected Anderson’s argument in
United States v. Royal,
Due process only requires adequate notice of the possibility that a defendant’s sentence will be based on quantity.
See Royal,
Anderson next argues that the district court improperly based his sentence on the entire weight of a substance containing only a trace amount of methamphetamine. Anderson submits that the district court should have based his sentence only on the amount of pure methamphetamine that was found, and not on the entire weight of the seized substance. The DEA chemist found a detectable amount of methamphetamine in the substance seized from Anderson’s home, and the substance weighed at least one kilogram.

United States v. Sherrod,
C
Anderson was arrested on October 27, 1986, and subsequently indicted under Count 4 for possessing an unregistered firearm, in violation of 26 U.S.C. §§ 5861(d) and 5871 (1988).
16
Count 4 described the firearm as an unregistered silencer with an overall length of four and three fourth inches, bearing no serial number.
See
Record on Appeal, No. 91-2270, vol. 1, at 186. At trial, the government introduced into evidence its Exhibit 4, which was identified as a rear portion of a siotic type silencer.
See id.
vol. 4, at 152,197. The government also introduced Exhibit 4-A,. which was identified as some of the internal parts of the front section of a silencer.
See id.
at 152, 201. The jury convicted Anderson on Count 4, and the conviction was affirmed on direct appeal. Subsequently, Anderson’s application for rehearing en banc was granted.
United States v. Anderson,
1
In appeal No. 91-2270, Anderson first argues that the district court violated the ex post fact clause by erroneously instructing the jury that they could find him guilty of possessing an unregistered firearm for having component parts of a silencer. Anderson claims that the instruction constituted an ex post facto violation, because at the time he committed the offense component parts of a silencer did not satisfy the statutory definition of a silencer.
At the time Anderson committed the offense, “firearm” was defined to include “[a]ny device for silencing or diminishing the report of any portable weapon ... and is not limited to mufflers or silencers for ‘firearms’ as defined.” 27 C.F.R. § 179.11 (1986); see also 26 U.S.C. § 5845(a)(7) (1988) (defining silencer by reference to 27 C.F.R. § 179.11). After Anderson’s arrest, § 5845(a)(7) was amended to define silencer as “any device for silencing, muffling or diminishing the report of a portable firearm, including any combination of parts, designed or redesigned, and intended for use in assembling or fabricating a firearm silencer or firearm muffler, and any part intended only for use in such assembly or fabrication.” 18 U.S.C. § 921(a)(24) (1988) (emphasis added); see also 26 U.S.C. § 5845(a)(7) (defining silencer by reference to § 921(a)(24)). 17
The district court’s instruction to the jury with regard to Count 4 was as follows:
*259 Count Four reads that ... Joe Alvin Anderson, defendant herein, did unlawfully and knowingly possess a firearm as defined in [26 U.S.C. § 5845(a)(7)]; that is, a silencer with an overall length of four and three quarters inches, bearing no serial number, which firearm was not registered to him....
And the statute says:
“A silencer for any firearm, whether or not such firearm is included within this definition.”
Now, Title 18, United States Code, section 921(24), defines firearm silencer as, “any device for silencing, muffling or diminishing the report of a portable firearm, including any combination of parts designed or redesigned and intended for use in assembling or fabricating a firearm silencer or firearm muffler and any part intended only for use in such assembly or fabrication.”
And, again, the statute provides under [26 U.S.C. § 5871], any person who fails to comply with any provision of this statute, and that’s the registration requirement, violates the law.
So, in Count Four, the government has alleged the defendant unlawfully and knowingly possessed a firearm silencer in violation of the law. That is, by failing to register the said firearm in the National Firearms Registration and Transfer Record.
Now, in order to establish the offenses prohibited by these statutes, there are two essential elements which the government must prove beyond a reasonable doubt:
First, that the defendant at the time and place alleged in the indictment knowingly possessed a firearm, it can be any other weapon or silencer, and
Second, that the firearm or any other weapon or silencer was not then registered to the defendant in the National Firearms Registration and Transfer Record.
It is not necessary for the government to prove that the defendant knew that the item described in the indictment was a firearm which the law requires to be registered. What must be proved beyond a reasonable doubt is that the defendant knowingly possessed the item as charged, that such item was a firearm, as defined before, and that it was not then registered to the defendant in the National Firearms Registration and Transfer Record.
Record on Appeal, No. 91-2270, vol. 5, at 299-800.
On collateral review of an allegedly erroneous jury instruction, we must determine “ ‘whether the ailing instruction by itself so infected the entire trial that the resulting conviction violates due process,’ ... not merely whether ‘the instruction is undesirable, erroneous, or even “universally condemned.” ’ ”
Henderson v. Kibbe,
the Federal Government, no less than the States, has an interest in the finality of its criminal judgments. In addition, a federal prisoner ..., unlike his state counterparts, has already had an oppor *260 tunity to present his federal claims in federal trial and appellate forums. On balance, we see no basis for affording federal prisoners a preferred status when they seek postconviction relief.
Id.,
Anderson argues that the district court’s instruction amounted to a due process violation, because the jury could have found him guilty on the ground that Exhibit 4 was a part designed and intended for use in assembling a silencer — which allegedly would have been impermissible. 19 Anderson bases his argument on the testimony of the government’s expert witness, who referred to Exhibit 4 alternatively as a silencer, and as part of a silencer. See Record on Appeal, No. 91-2270, vol. 4, at 197, 231, 236-37. Nonetheless, Anderson has not shown that the jury found Exhibit 4 to be a part designed and intended for use in assembling a silencer. It appears more likely that the jury found Exhibit 4 to be a device that diminished the report of a weapon, and therefore met the statutory definition of a silencer. See 27 C.F.R. § 179.11 (1986). There was uncontradicted evidence that Exhibit 4 reduced the report of a pistol in Anderson’s possession by nine decibels. See id. vol. 4, at 198-200, 232. Furthermore, the government’s only argument was that Exhibit 4 was a firearm because it diminished the report of a weapon found in Anderson’s possession. See id. at 198-201; id. vol. 5, at 275-76. The government never argued that Exhibit 4 was a part designed and intended to be used in the assembly of a silencer. See id. vol. 4, at 133-34, 197-201; id. vol. 5, at 275-76. Therefore, it is unlikely that the jury based its verdict on a finding that Exhibit 4 was a component part of a silencer.
Anderson also argues that the jury could have based its conviction on Count 4 solely on Exhibit 4-A, which was identified as component parts of a silencer. We disagree. The district court, in denying Anderson’s § 2255 motion, stated that “the instruction given by the trial court specifically identified the silencer alleged in Count Four as ‘a silencer with an overall length of four and three quarters inches, bearing no serial number.’ Such a description could have allowed the jury to consider only exhibit 4 with regard to Count Four.” Record on Appeal, No. 91-2270, vol. 1, at 23. Although there is no evidence in the record that explicitly states the lengths of Exhibits 4 and 4-A, it is clear that all the parties believed that Count 4 — referring to a silencer four and three fourth inches long — described Exhibit 4. Furthermore, the parties do not dispute that Exhibit 4 had an overall length of four and three quarters inches, and Anderson does not argue that Exhibit 4-A was of that length. We conclude that Count 4 — by describing the silencer as being four and three quarters inches long — referred to Exhibit 4, and not 4-A. As a result, the district court’s instruction only permitted the jury to convict Anderson for possession of Exhibit 4. 20 *261 Therefore, we hold that the district court’s instruction by itself did not so infect the trial that the resulting conviction violated due process.

Anderson next claims that he had ineffective assistance of counsel because his counsel failed to object to the district court’s instruction as discussed in Part II. C.l. To prevail, he must prove that (1) his counsel’s performance was deficient, and (2) the deficient performance prejudiced his defense.
Strickland v. Washington,
D
Finally, in appeal No. 91-2834, Anderson alleges that the district court denied him his right of allocution at his probation revocation hearing. The government concedes that the district court erred by not specifically addressing Anderson and asking him if he wanted to exercise his right of allocution.

. However, we have on numerous occasions "upheld multiple convictions and separate sentences even where the defendant arguably engaged in but a single act, agreement or course of conduct.”
United States v. McDonald,
. At oral argument Anderson conceded that quantities of methamphetamine in its final powdered form were found in his home, and does not argue that his conviction under Count 1 for the manufacture of methamphetamine was not supported by the evidence. Anderson argues only that there was no evidence that he was attempting to manufacture a second batch of methamphetamine. See Brief for Anderson, No. 91-2293, at 12-13 ("At the time of his arrest, Mr. Anderson was seated at his kitchen table, ... not in the lab ‘cooking up’ another batch of drugs additional to that which was seized.”).

. Agent Lewis, a special agent with the DEA, was assigned to the Clandestine Lab Group, which was responsible for investigating clandestine laboratories that were engaged in the manufacture of controlled substances such as methamphetamine. See id. vol. 10, at 3-66. Agent Lewis testified that he had seen 35-40 metham *257 phetamine laboratories in his career. See id. at 3-69.
. Anderson also claims that his conviction for possessing an unregistered silencer should not have been included in the calculation of his criminal history category because the conviction was obtained in violation of the ex post facto clause and his right to the effective assistance of counsel. See Brief for Anderson, No. 91-2293, at 13. Because we uphold Anderson’s conviction, this argument is without merit. See discussion infra part II.C.
. Section 841(b) sets forth three penalty ranges for the offense of manufacturing methamphetamine, based upon the total amount of methamphetamine involved: (1) ten years to life if "100 grams or more of methamphetamine ... or 1 kilogram or more of a mixture or substance containing a detectable amount of methamphetamine” were involved; (2) five to forty years if "10 grams or more of methamphetamine ... or 100 grams or more of a mixture or substance containing a detectable amount of methamphetamine" were involved; and (3) zero to twenty years for all other methamphetamine offenses (except those involving death, serious bodily injury, or repeat offenders). See 21 U.S.C. § 841(b) (1988).
.The Circuits are split on this issue.
Ruff,
. Anderson was also charged with three other counts of unlawful possession of a firearm.
. Section 5845(a)(7) was amended in May 1986, before Anderson committed the offense. The amendment did not take effect, however, until November 15, 1986, three weeks after Anderson committed the offense.
. The Supreme Court noted that this standard is stricter than that used to review erroneous jury instructions on direct appeal: “[T]he burden of demonstrating that an erroneous instruction was so prejudicial that it will support a collateral attack on the constitutional validity of a state court’s judgment is even greater than the showing required to establish plain error on direct appeal.”
Henderson,
. Because we hold that the district court’s instruction did not amount to plain error, we do not decide whether the district court erred in instructing the jury that the statutory definition of a silencer included component parts.
. Because Anderson does not argue that the jury disregarded the district court's instructions, we presume that the jury followed its instructions.
