Jury Instruction

Sentencing: Firearms Mandatory Minimums and Guidelines

This is not law. It records what the body named below published, on the date shown. Commentary, guidance and model instructions may be persuasive, but none of them carries the force of law, and none is a statement of what the law requires.

Source: Massachusetts Sentencing Commission, Sentencing Guidelines: Mandatory Offenses
Note: For firearms offenses with mandatory minimums, the Commission adopted the statutory penalty provisions and allows no departures from the minimum term of incarceration. Although firearms offenses do not appear on the sentencing guidelines grid, they are assigned offense seriousness levels on the Master Crime List for criminal history purposes.

Key Sentencing Principles

Federal ACCA (18 U.S.C. § 924(e))

The Armed Career Criminal Act imposes a 15-year mandatory minimum for anyone convicted of being a felon in possession of a firearm (18 U.S.C. § 922(g)) who has three prior convictions for "violent felonies" or "serious drug offenses." ACCA is a federal sentencing provision; there are no Massachusetts model jury instructions for it. The state analog is § 10(a)/(c)/(h)(1) with 3 prior violent/drug crimes (Level 8 above).
