Maxim Defense MD15 Duty Precision 5.56 NATO 18" Rifle

Maxim Defense set the MD15 Duty Precision up for shooters who want an AR-15 that holds a group off a bipod or a bag. The 18" barrel splits the difference between a 16" carbine and a 20" rifle, and the Magpul PRS Lite stock behind it adjusts for length of pull and comb height so the same rifle fits a shooter stretched out in prone and folded up behind a barricade. The receiver set is aluminum with a Picatinny top rail, and the M-Rax handguard uses M-Slot attachment points for a bipod, a light, or a hand stop.

The details are where this separates from a parts bin build. A Radian charging handle replaces the standard latch with something that runs from either side and under load, which matters when the support hand is busy holding a bag in place. The muzzle carries a Maxim QD flash hider, so a compatible suppressor mounts without a trip to the bench. Furniture is black polymer throughout and the receiver is black anodized. Chambering it in 5.56 NATO keeps ammunition cheap enough to actually practice with, and trigger time matters more to precision work than any single component bolted to the rifle.
