Built on the AR-15 platform with a direct-impingement system, this DD-15 pairs a flat-top upper receiver with a forward assist and ejection-port cover to a Davidson Defense lower marked 'DAVIDSON DEFENSE INC' with the DD shield logo and SAFE/FIRE selector legend. The handguard is a Rise Armament free-float M-LOK design with a continuous 12 o'clock Picatinny rail, laser marked 'RISE ARMAMENT CAGE: #6XW00 PAT. PENDING'.
The 18 in 416R stainless barrel is a heavy-profile tube for rigidity, threaded at the muzzle, and capped with a knurled thread protector. Chambered in .22 ARC, the rifle runs on 6.5 Grendel/6mm ARC pattern magazines, and capacity is 5+1. A black nitride BCG supports smooth function and ease of maintenance.
Furniture and controls are purposefully selected: a Magpul PRS Lite stock provides adjustable length of pull and comb height (length of pull set at 14.5 in), and a B5 Systems pistol grip offers a solid interface. The charging handle is a Rise Armament AR-15/M16 unit. A polymer flip-up front sight is installed.
Made in the United States, this configuration combines name-brand components with careful parts selection for the .22 ARC chambering. The result is a clean, modern AR-15 build with a 416R stainless barrel and black nitride BCG, threaded muzzle protection, and magazine compatibility aligned with the Grendel/6mm ARC pattern.
