Rearden Manufacturing Group Llc Mini Muzzle Brake 0.571 11/16-24 Thread Square Shoulder Blk
The Rearden Mini Muzzle Brake in 0.571" diameter with 11/16-24 thread is a precision-engineered muzzle device built for shooters running suppressed rifle systems. This square-shoulder design pairs with Rearden's Atlas and Plan B suppressors, giving you a rock-solid platform for sub-sonic or supersonic shooting without the bulk of a full-size brake. If you're building a compact tactical rifle, precision bolt gun, or any short-barreled setup where real estate matters, this is a no-nonsense foundation for your sound signature control.
Machined from 17-4 PH H900 stainless steel and finished in black nitride at 67 HRC surface hardness, the Mini Brake resists carbon fouling and handles the punishment of repeated suppressor attachment and removal. The square shoulder ensures repeatable suppressor indexing—critical for maintaining zero and keeping your suppressor tracking true with your bore. Thread size and shoulder geometry are precisely matched to Atlas and Plan B suppressors, so you know it'll mate cleanly without adapters or improvisation.
Installation is straightforward but demands attention to detail: clean all threads and tapers, torque the brake to 15–25 ft-lbs, confirm the shoulder is seated square against your barrel, then mount your suppressor and torque it to 10 ft-lbs. Use an alignment rod during setup to verify your entire system runs true. Black nitride finish handles high-round-count shooting and suppressor use without losing its edge.
