Geissele Super Duty MOD1 300 Blackout 8" SBR Rifle

Geissele Super Duty MOD1 .300 BLK 8" Black Short Barrel Rifle 08-525B-SBR carries the same core Super Duty engineering as the MOD1-A builds, just on a standard Mil-Spec lower rather than the billet ambi receiver - a straightforward, proven configuration for shooters who don't need mirrored bolt/mag controls. The Geissele Super Duty MOD1 .300 BLK 8 barrel is cold hammer forged, chrome-lined, and cut to a 1:7 twist, chambered specifically for 300 Blackout's dual-role ballistics - full-power supersonic and a genuinely quiet subsonic option once a suppressor's involved. A custom pistol-length gas system runs through an Antistrike Super Compact Gas Block, and Geissele's Phased Array® gas system with Tri-Port™ metering keeps cycling clean across that wide spread of ammunition without needing an adjustable gas block. This 300 Blackout SBR channels that gas through a Nanoweapon®-coated Reliability Enhanced Bolt Carrier Group with a forged Stressproof Bolt, built for round counts that would push a standard bolt toward failure. An ambidextrous Super Configurable Safety comes standard even on this Mil-Spec lower, and the SSA-E X® trigger with Lightning Bow® delivers a clean, repeatable break. A 7" MK16 rail with Geissele's Center Tab mating keeps the front end rigid.
