Q LLC Mini Fix .300 Blackout Bolt-Action Rifle 16-inch Grey

The Q LLC Mini Fix in .300 Blackout (Q LLC part no. MINIFIX-300BLK-16IN-CPROOF) is a bolt-action rifle built around a one-piece receiver where the bolt locks directly into the barrel, allowing user-level barrel changes without a gunsmith. Its 16-inch tapered, threaded barrel is finished in grey and cut with a twist rate designed to stabilize both supersonic and subsonic .300 Blackout loads, making it a natural fit for suppressed shooting. It feeds from AR-15/M4-pattern magazines, weighs roughly 5 lbs, and includes a free-float M-LOK handguard with a Picatinny top rail. The adjustable folding stock and short-throw 45-degree bolt round out a genuinely innovative, compact bolt-action design.
