Diamondback DB15 Pistol, 5.56 NATO, 7-Inch, with Brace

The Diamondback DB15 pistol in 5.56x45mm NATO with a 7-inch barrel (brand part no. DB1921K001) pairs a pistol-length 4150 chrome moly barrel with a stabilizing brace in place of a shoulder stock for a compact, maneuverable build. Diamondback gives the Black Nitride barrel a 1-in-8 twist and threads the muzzle 1/2×28, and the shot-peened mil-spec 8620 bolt carrier runs on the same pistol-length gas system as the rest of the DB15 line. A 6-inch M-LOK handguard covers the barrel, a Magpul MOE grip provides the hold, and the upper is optic-ready with no fixed sights. Among AR pistols built with a brace for one-handed stability, this DB15 configuration favors shooters who want a short, close-quarters 5.56 platform.
