The Maxim Defense MD15 Duty Precision is a semi-auto AR-pattern rifle chambered in 6mm ARC, built for shooters who want long-range performance without stepping up to a heavier bolt gun (brand part no. MXM49282). It pairs an 18-inch threaded barrel with a black anodized aluminum receiver and Picatinny rail for mounting optics and accessories. A Magpul PRS Lite stock lets shooters dial in length of pull and comb height for a precise, repeatable cheek weld, while the M-Rax/M-Slot handguard keeps the barrel free-floated for consistent accuracy. This is a precision-oriented build for shooters who want to stretch their effective range without giving up semi-auto follow-up shots.
