In 1996 the Iowa legislature adopted a mandatory minimum sentence for certain forcible felonies, i.e., murder in the second degree, sexual abuse in the second degree, kidnapping in the second degree, and robbery in the first or second degree. 1996 Iowa Acts ch. 1151, § 3 (codified at Iowa Code § 902.12 (1997)). The legislature provided that an inmate sentenced under section 902.12 is eligible for a reduction of the sentence of one day for each day of good time but the total days which may be accumulated shall not exceed fifteen percent of the inmate’s total sentence of confinement. 1996 Iowa Acts ch. 1151, § 4 (codified at Iowa Code § 903A.2 (1997)). In this appeal we must determine if the provisions of section 902.12 violate the Eighth Amendment to the United States Constitution that prohibits cruel and unusual punishment. We find neither the statute nor the sentence imposed violate the constitutional provision. We affirm.
I. Background.
Between October 2 and October 7, 1996, Roger Conrad Lara robbed eleven different businesses in Black Hawk County, Iowa. Lara was arrested and charged with eleven counts of robbery in the first degree in violation of Iowa Code section 711.2. Lara pled guilty to the charges and was sentenced to serve an indeterminate sentence of twenty-five years for each count. The sentences were to run concurrently. On appeal Lara asserts that Iowa Code section 902.12, requiring him to serve eighty-five percent of the maximum term of his sentence, is unconstitutional. We review constitutional claims de novo.
State v. Washburne,
II. Discussion.
The Eighth Amendment to the United States Constitution prohibits “cruel and unusual” punishment. The Eighth Amendment is applicable to the states through the Fourteenth Amendment.

Rhodes v. Chapman,
*785
Wé have said punishment may be cruel and unusual either because it inflicts torture or is otherwise barbaric or because it is “so excessively severe that it is disproportionate to the offense charged.”
State v. Robbins,
The disproportionality test enunciated in
Solem
was called into question by
Harmelin v. Michigan,
Substantial deference is afforded to the legislature in setting the penalty for crimes.
Solem,
Lara challenges the constitutionality of the requirement that he serve eighty-five percent of his sentence. In prior cases, we have upheld mandatory sentences.
See State v. Horn,
With
Harmelin
to guide us, we look at the crime committed and the sentence imposed. Lara was convicted of eleven counts of first-degree robbery. First-degree robbery occurs when a person, while perpetrating a robbery “inflicts or attempts to inflict serious injury or is armed with a dangerous weapon.” Iowa Code § 711.2. Lara was armed with a CO2 pistol. We have found such a weapon to be a dangerous weapon.
State v. Dallen,
III. Disposition.
We find no merit in Lara’s claim that a sentence imposed under Iowa Code section 902.12 constitutes cruel and unusual punish *786 ment. Neither the length of the mandatory sentence nor the requirement that he serve eighty-five percent of it before he is eligible for parole or work release violates his constitutional rights. We therefore affirm the sentence imposed by the district court.
AFFIRMED.
Notes
. Lara does not raise Iowa’s constitutional prohibition against cruel and unusual punishment in his appeal. See Iowa Const, art. I, § 17.
