On March 18,1997, a jury convicted Defendant Anthony Gault of possession of a controlled substance with intent to distribute, in violation of 21 U.S.C. §§ 841(a)(1) and 841(b)(1)(A), and aiding and abetting, in violation of 18 U.S.C. § 2. Defendant was sentenced to 210 months imprisonment and five years of supervised release. Defendant raises three issues on appeal. First, Defendant argues that the use of voter registration lists as the source of jury venires in the United States District Court for the District of New Mexico violates the Fifth Amendment equal protection clause and the Sixth Amendment right to a representative jury. Second, Defendant argues that the district court erroneously limited the cross-examination of a government witness. Third, Defendant argues that the district court erred in refusing to grant his request for a base offense level reduction pursuant to § 3B1.2 of the United States Sentencing Guidelines (hereinafter “U.S.S.G.”). Our jurisdiction arises under 28 U.S.C. § 1291 and 18 U.S.C. § 3742. For the reasons set forth below, we affirm.
I.
The background of this ease is set forth in
United States v. Gault,
II.
Defendant challenges the jury selection system in the federal district courts in New Mexico, arguing that the use of voter registration lists to select jury panels has systematically excluded Hispanics, Native Americans, and African Americans from jury service, in violation of the Fifth and Sixth Amendments. We disagree.
On December 9, 1996, after a jury had been chosen, but before the jury was sworn, Defendant moved to dismiss the jury-panel. Defendant sought to challenge the constitutionality of the jury selection process in the Abuquerque/Santa Fe Division of the United States District Court for the District of New Mexico (“the District”).

The district court dismissed the jury and ordered briefing on the issue. In lieu of an evidentiary hearing, the parties requested permission to submit transcripts of testimony from a November 26-27, 1996, hearing held before the Honorable Martha Vazquez, during which evidence was presented in the case of
United States v. Cesar Gonzales,
No. 95-0538 (D.N.M.), regarding the constitutionality of the District’s jury selection plan. After considering the material presented by the parties, the district court, in a thorough and well-reasoned opinion,
United States v. Gault,
In 1968, the District, in compliance with the Jury Selection and Service Act of 1968, 28 U.S.C. § 1861, adopted a “Plan for Random Selection of Jurors.” The plan provides for the selection of prospective jurors *1402 through voter registration lists. Under the plan, the Clerk of the Court determines the number of jurors needed for a particular division of the District. Jurors are then randomly selected from the voter registration lists from the counties in the division. Those names are placed on a “Master Juror Wheel.” Each of the individuals on the “Master Juror Wheel” receives a juror qualification questionnaire. As part of the questionnaire, potential jurors are asked to identify their race and/or ethnicity. The registered voters who return the questionnaires and are not disqualified, excused or exempted, are placed on the “Qualified Juror Wheel.” 3 The jury venires are then selected randomly from the “Qualified Juror Wheel.” Defendant argues that this method of jury selection systematically underrepresents Hispanics, Native Americans, and African Americans, and is therefore unconstitutional.
The Sixth Amendment guarantees a defendant the right to a jury pool comprised of a fair cross-section of the community.
United States v. Ruiz-Castro,
In order to establish a prima facie violation of the Sixth Amendment, Defendant must show: (1) that the group alleged to be excluded is a distinctive group in the community; (2) that the representation of this group in jury venires is not fair and reasonable in relation to the number of such persons in the community; and (3) that this underrepresentation is due to systematic exclusion of the group in the jury-selection process.
Yazzie,
Although Fifth Amendment equal protection and Sixth Amendment fair-cross section cases are not identical, both require similar showings.
See United States v. Yazzie,
When analyzing jury composition challenges, the court must look to the relevant Qualified Juror Wheels.
Id.
at 427. In this case, the grand jury which indicted Defendant was selected from the 1993 wheel and the petit jury was selected from the 1995 wheel. Thus, the district court relied on absolute and comparative disparity figures for 1993 and 1995. The district court found
*1403
absolute disparities for Hispanics of 7.00% and 5.74% and comparative disparities of 19.94% and 16.35% for 1993 and 1995, respectively. The absolute disparities for Native Americans were 3.26% and 3.19%, with corresponding comparative disparities of 32.44% and 31.74%. The statistics for African Americans were .28%, .66%, 15.14% and 35.68%. Thus, absolute disparities ranged between .28% and 7.00% and comparative disparities between 15.14% and 35.68%. These percentages are much lower than those upon which courts have relied to find constitutional violations.
See Castaneda,
In this circuit, we have held that an absolute disparity of 4.29% and a comparative disparity of 46.3% did not violate the Fifth or Sixth Amendments.
Yazzie,
In light of
Yazzie
and the record before us, we are unable to find that the disparities here are so “gross” or “marked” as to establish a substantial underrepresentation under equal protection, or that the representation of these groups on the jury panels is not fair and reasonable under the Sixth Amendment.
See United, States v. Test,
III.
Next, Defendant argues that his Sixth Amendment confrontation rights were violated because the district court denied him the opportunity to effectively cross-examine DEA forensic chemist Buddy Goldston. Goldston performed the laboratory tests identifying the substance found in Defendant’s carry-on bag as PCP. Defendant sought to question Goldston about a former DEA colleague’s submission of falsified reports. The DEA agent, Ann Castillo, had admitted to failing to perform the controlled substance tests upon which her reports were based. The district court refused, under Fed.R.Evid. 403, to allow the cross-examination, on the grounds that the probative value was outweighed by the risk of unfair prejudice and confusion of the issues.
We review de novo whether a defendant’s Sixth Amendment confrontation rights were violated by cross-examination restrictions, and whether any such violation was harmless.
United States v. Pedraza,
In light of the limited relevance of Castillo’s conduct, we hold that the district court’s restriction of Goldstoris cross-examination did not violate Defendant’s Sixth Amendment rights. The record is clear that Castillo was not involved in the laboratory tests performed in this case. There was also no suggestion of widespread misconduct or ini *1404 proper procedures at the Dallas DEA laboratory. As the district court noted, Defendant had no reason to believe that Goldston may have acted improperly or had falsified test results. Defendant reviewed Goldston’s worksheets and graphs of the tests performed and found no evidence of irregularities. Nothing in Goldstoris work records suggested that he may have failed to perform the underlying tests. Based on the foregoing, we agree with the district court that there was an insufficient basis from which to conclude that the failure of one DEA chemist in Dallas, Texas, to conduct laboratory tests suggests that the work of another chemist in the same lab was also unreliable.
Moreover, the jury had sufficient information to assess the reliability of Goldston’s testimony. Defendant cross-examined Goldston regarding the supervision he received in the laboratory, the types of tests performed in this case, and the accuracy of the test results. Accordingly, Defendant’s confrontation rights were not violated by the district court’s refusal to allow cross-examination regarding Castillo’s conduct.
IV.
We now turn to Defendant’s final issue on appeal. Defendant argues that the district court erred by declining to grant him a downward adjustment under U.S.S.G. § 3B1.2 as a minimal or minor participant. We review the district court’s findings for clear error,
United States v. Ayers,
Section 3B1.2 permits the district court to decrease the base offense level if the defendant’s role in the offense makes him “substantially less culpable than the average participant.” U.S.S.G. § 3B1.2, comment, (backg’d). The four-level decrease for minimal participation under § 3B 1.2(a) “will be used infrequently” and should be reserved for “defendants who are plainly among the least culpable of those involved in the conduct of a group.” U.S.S.G. § 3B1.2, comment. (nn.1-2). The two-level decrease for minor participation applies to individuals who are “less culpable than most other participants, but whose role could not be described as minimal.” U.S.S.G. § 3B1.2, comment, (n. 3).
The jury convicted Defendant of possessing, with intent to distribute, more than a kilogram of PCP. A special agent of the Drug Enforcement Agency discovered the PCP in Defendant’s carry-on luggage after boarding the train during a stop at the Amtrak station in Albuquerque, New Mexico. After his conviction, Defendant sought a § 3B1.2 downward adjustment for his role in the offense, arguing that he was merely a drug “mule” or “courier”.
On appeal, Defendant argues that the district court based its refusal to grant the downward departure on an incorrect statement in the presentence report. The presentence report stated that “the defendant was the only person involved in the Amtrak train arrest ... [and] the United States Probation Office has not received any additional information stating that there was any additional defendants or a scheme or organization which the defendant associated with.” Defendant argues this finding is erroneous because the circumstances suggest that other participants necessarily were involved in the offense. Specifically, Defendant asserts that in order to transport and distribute such a large amount of PCP, Defendant must have been part of a “complex, extensive drug scheme” involving “many individuals.” During the sentencing hearing, the district court concluded that the evidence did not support a finding that Defendant was only a minimal or minor player in the offense. The district court was “ ‘not bound to accept the defendant’s own declarations about his level of participation in the crime.’ ”
United States v. Caruth,
The judgment of the district court is
AFFIRMED.
Notes
. In Gault I, we reversed the district court’s order suppressing the PCP.
. The. District of New Mexico is subdivided into three divisions for purposes of jury selection: . Albuquerque/Santa Fe, Roswell, and Las Cruces.
. In order to qualify for juty service, individuals must be citizens aged 18 or older, who have resided in New Mexico for a full year, who can speak, read, write and understand the English language, and who do not have a felony record. Exemptions from jury service are granted to full-time elected officials, military personnel, and full-time members of fire and police departments.
. We note that even if Defendant had established that other individuals were involved, an adjustment is not required merely because there were multiple participants.
Caruth,
