Designed to replace an existing AR-15 upper assembly, DPMS’ blowback-operated, .22 Long Rifle-chambered flat-top uppers are offered in A3 and varmint configurations with 16-inch barrels featuring 1:16-inch twist rifling.
The A3’s barrel has a fixed A2 front sight and A2-style flash hider, which is attached via 1/2x28 threads; the second variant’s barrel is left full-diameter and features neither sights nor threading for the addition of a flash hider or a suppressor. The forged 7075-T6 aluminum receivers have Melonite-coated stainless steel bolt carrier groups with fixed extractors and fully functional charging handles, ejection port doors and brass deflectors.
The units also work with most AR handguards and free-float tubes. Included with each upper is a 10-round-capacity Black Dog Industries magazine. Price: $399-$425.
