What is the maximum sentence for a drug dealer convicted of a firearm charge and the minimum sentence for the firearm charge?

The firearm count, pursuant to 18 U.S.C. 924(a)(2), carries a maximum sentence of ten years of imprisonment and no mandatory minimum. The drug count, pursuant to 21 U.S.C. 841(b)(1)(A) and 851, carries a maximum sentence of life imprisonment and a mandatory minimum that depends upon the application of prior-felony enhancements: the baseline is a mandatory minimum of ten years of imprisonment; a prior conviction for a felony drug offense makes a defendant eligible for a mandatory minimum of twenty years; and two such prior convictions make a defendant eligible for a mandatory life sentence. Pursuant to 851, the "imposition of an enhanced penalty is not automatic," but is triggered when "the Government files an information notifying the defendant in advance of trial (or prior to the acceptance of a plea) that it will rely on that defendant's prior convictions to seek a penalty enhancement."
