The JRC Rail Model in 10mm Auto (brand part no. JRC10G3-TBBL) is a semi-automatic pistol-caliber carbine operating on simple, reliable straight blowback, pairing a 17-inch button-rifled threaded barrel with a 1:16-inch twist rate. Just Right Carbines threads the muzzle 9/16×24, uses a fully ambidextrous bolt configurable for left- or right-hand ejection, and machines the receiver from 6061-T6 aluminum. A 13-inch free-float KeyMod handguard with a top Picatinny rail, a standard M4 buffer tube with a 6-position buttstock, and standard AR-15 furniture and trigger components round out the build. The carbine accepts standard Glock magazines and feeds from an included 15-round magazine. Among AR-platform rifles in the AR rifles category, the JRC Rail Model favors shooters who want a hard-hitting 10mm carbine that shares Glock magazines.
