Q The Lefty, 5.56 NATO/6mm ARC, 6.5 in., 14.2 oz, Low Blow, Quickie Fast-Attach, Black, Suppressor By now you know Q's thoughts on low back pressure suppressors. Q builds systems designed to work with and without suppressors, but not everyone does. When shooters asked for a suppressor that keeps other systems working right, Q built The Lefty: its take on a hybrid-construction, 3D printed, no-flash, low-gas suppressor. The Lefty is rated for 5.56 NATO and 6mm ARC. It is 6.5 inches long, 1.625 inches in diameter and weighs 14.2 ounces, and it mounts with Q's QUICKIE Fast-Attach system. Low Blow Technology Low Blow is Q's approach to controlling back pressure by managing how gas actually moves through the suppressor instead of just trapping it in a traditional baffle stack. It uses a directional flow path to push gas forward and vent it in a controlled way, which reduces port pressure, slows cyclic rate and cuts down the gas that reaches the shooter. Reliable on Unoptimized Rifles The Lefty was created to keep rifles that were not designed around suppressors running smoothly. It adds much-needed suppression without upsetting the gas system, and less back pressure also means less gas in your face and, more importantly, your lungs. No Flash The Lefty is designed to eliminate flash at the muzzle, which matters when the lights go down and you need to keep your night vision and your eyes working. Three-Piece, Rebuildable Construction Under the hood, The Lefty uses three primary components: a mount, a stainless steel tube and a 3D printed stainless steel core that integrates the end cap. Q prints the part that does the work so it can create complex internal geometry and gas flow paths that cannot be machined, while the conventional tube adds strength, durability and serviceability. That design also means it can be rebuilt if it is damaged, which matters for duty use. Who It Is For The Lefty is a strong match for short-barreled 5.56 and 6mm ARC rifles, duty rifles and any AR that was set up to run unsuppressed. If you have ever fought gas in the face or erratic cycling with a conventional suppressor, a low back pressure design like The Lefty keeps the rifle running the way it did before. Full Auto Rated, No Barrel Restrictions Q rates The Lefty for full auto fire and lists no barrel length restrictions. It mounts with the QUICKIE Fast-Attach system on Q's Cherry Bomb and Rear End muzzle devices and has a black nitride finish.
