Geissele Super Duty MOD1-A .300 BLK 8" Black SBA3 - AR-15 Pistol

The Super Duty MOD1-A .300 BLK platform with patented Phased Array gas — in pistol configuration with SB Tactical SBA3 brace, in black. The Geissele Super Duty MOD1-A .300 BLK Pistol pairs the Phased Array Tri-Port gas system that eliminates the need for an adjustable gas block with the HUXWRX Flash Hider-QD 762, delivering reliable cycling with both supersonic and subsonic .300 BLK regardless of suppressor attachment.

The Geissele Super Duty MOD1-A .300 BLK Pistol is an AR-pattern pistol featuring an 8-inch cold hammer-forged chrome-lined .300 BLK barrel with 1:7 twist, Phased Array Tri-Port gas system, SSA-E X two-stage trigger with Lightning Bow, fully ambidextrous MOD1-A controls, SB Tactical SBA3 brace, and black finish.

Four features define the Super Duty MOD1-A .300 BLK Pistol's operational advantage. The patented Phased Array gas system with Tri-Port technology precisely balances the gas impulse for consistent cycling across supersonic and subsonic .300 BLK loads both suppressed and unsuppressed — eliminating the need for an adjustable gas block that requires manual tuning as the ammunition or suppressor configuration changes. The HUXWRX Flash Hider-QD 762 provides a direct, tool-free interface for HUXWRX QD suppressors, enabling rapid transitions between suppressed and unsuppressed configurations without swapping muzzle devices. The Nanoweapon-coated Reliability Enhanced Bolt Carrier Group with Forged Carpenter 158+ Stressproof Bolt provides 5x the fatigue life of a mil-spec bolt and the low-friction bore surface that reduces cleaning frequency in the sustained-fire suppressed use that .300 BLK pistol platforms are often designed for. Fully ambidextrous MOD1-A controls — including left-side magazine release, right-side bolt catch and release, and Maritime Bolt Catch — provide instinctive operation from either hand under any condition.
