Q Minifix SBR - 300 Blackout

Q MINIFIX SBR - 300 BLACKOUT SHORT-BARRELED RIFLE, 8" BARREL, SIDE-FOLDING STOCK

The Q MiniFix takes the full-size Fix bolt-action platform and shrinks it into a compact SBR. Chambered in .300 Blackout, it pairs a smaller action and an 8 inch barrel with a side-folding stock, so the overall footprint is about as small as a bolt gun gets. The barrel runs a 1:5 twist built to stabilize .300 Blackout across the board, with particular attention to the heavier subsonic loads this caliber is known for. 

A one-piece receiver keeps the action rigid and accuracy consistent, and the 2-stage match trigger delivers the same clean break shot after shot. Q's fully adjustable stock lets you dial in length of pull and head position so your cheek weld doesn't change from one shooting position to the next, and the 45-degree short-throw bolt handle keeps follow-up shots fast when you're cycling fresh rounds. 

CAPITOL ARMORY'S OPINION

Bolt-action SBRs in .300 Blackout are not overly common, and most bolt guns chambered for it are built around a full-size action that doesn't shrink down well. The MiniFix solves that by starting with a smaller action from the ground up, which is why it can get down to an 8-inch barrel and a folded footprint without feeling like a compromise. The 1:5 twist barrel is also a good choice for subsonic .300 Blackout specifically to ensure heavier subsonic projectiles stabilize properly. The 5/8x24 threaded muzzle and Quickie Fast-Attach system make this an easy rifle to build a suppressed setup around, since mounting and removing a can does not require tools. If you want a genuinely short, suppressor-ready bolt gun for subsonic .300 Blackout, the MiniFix is the best option on the market right now.
