Geissele Super Duty Pistol | .300 BLK | 8″ | 08-518S

The Geissele Super Duty MOD1 is an AR-style pistol built for dependable performance in .300 AAC Blackout. This configuration pairs an 8″ cold-hammer-forged, chrome-lined barrel with a Geissele SMR MK16 handguard and a Flat Dark Earth finish for durable, disciplined handling. Its feature set — including a two-stage SSA-E X trigger, Phased Array gas system and SBA3 brace — makes it suitable for precision short-range shooting and guided training drills. For an optic under $1,000 that complements this pistol, consider a Vortex Strike Eagle 1-6×24 for versatile close-to-mid-range target work.
