Garrow Firearms Development unveiled its latest innovation, a gas operated direct impingement upper for the AR-15 chambered in .17 HMR.
Designed to give AR shooters the ability to easily convert their AR-15 into a varmint hunting, target or training rifle, the GFD AR17HMR touts minimal moving parts and easy maintenance. The 18-inch barrel is constructed of stainless steel and boasts an integral ramp Garrow Firearms says ensures dependability. The barrel also features a threaded design for flash-hiders or muzzle breaks.
“The GFD AR17HMR is the World’s First gas-operated direct impingement, semi-automatic rimfire upper receiver for the AR-15 rifle,” Garrow Firearms said in a statement. “It is designed to prevent firing unless locked in place, eliminating the dangers of its blowback action predecessors.”
The complete upper touts a free-float handguard, hardened 4140 tool steel bolt and gas key, dual extractors and fixed ejector. The setup ships alongside two 10-round magazines, buffer system and operator’s manual.
Available in three models — forged, billet and billet with M-LOK/Picatinny Rail — the GFD AR17HMR offers a retail price starting at $599.
