LMT Defense 4 Port Regulator Brake 7.62 5/8"x24 Threads (Dead Air Xeno Compatible) - SKU: R-RMB5824762 - UPC: 850076573188
Product Description
The LMT (Lewis Machine & Tool) R-RMB5824762 4-Port Regulator Muzzle Brake is an ultra-durable recoil reduction device engineered for 7.62mm / .308 caliber rifles with 5/8"x24 thread profiles. Designed with four side-concussive porting chambers, this muzzle brake redirects expanding high-pressure propellant gases outward and upward to significantly reduce felt recoil impulse and muzzle climb on heavy-caliber platforms.
Serving as a mounting foundation for suppressed setups, the Regulator brake acts as a direct quick-detach (QD) mount interface for Dead Air's Xeno Mount suppressor system. Utilizing left-handed interface threads, the Xeno system prevents the muzzle brake from backing off the barrel shoulder when unthreading your silencer after rapid firing schedules.
Precision CNC-machined from high-strength alloy steel and treated with a durable, heat-resistant black coating, the LMT R-RMB5824762 also functions as an effective sacrificial baffle inside the suppressor's expansion chamber, extending the service life of internal suppressor baffles on hard-use tactical, hunting, and precision rifle builds.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits barrels chambered in 7.62mm NATO, .308 Winchester, 6.5 Creedmoor, or smaller with 5/8"-24 thread pitch. Compatible with Dead Air Xeno Omni/Adapter suppressor mounts.
- Verify host firearm is completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Clean barrel muzzle threads thoroughly to remove carbon fouling, dirt, and old threadlocker residue.
- Apply proper timing shims to correctly index the brake ports horizontally, along with high-temperature threadlocker (such as Rocksett).
- Thread the R-RMB5824762 muzzle brake onto the barrel shoulder by hand to prevent cross-threading.
- Torque the muzzle device to 25–30 ft-lbs using an appropriate armorers wrench on the precision wrench flats, and verify bore clearance with an alignment rod prior to live-fire.
Key Features
- 4-Port Concussive Recoil Reduction: Lateral ports vent gases sideways to minimize rearward felt recoil and keep sights flat on target.
- Dead Air Xeno Compatibility: Interfaces directly with Dead Air Xeno Omni/Adapter suppressor mounts for fast QD silencer attachment.
- Left-Handed Xeno Threads: Prevents accidental unthreading of the muzzle device from the barrel when spinning the silencer off.
- Sacrifical Baffle Action: Protects primary silencer baffles from premature erosion under high-volume firing.
- 5/8"x24 Thread Pitch: Standard mounting thread pattern for 7.62 NATO / .308 Win / 6.5 Creedmoor rifle barrels.
- Heat-Resistant Black Coating: Shielded against chemical solvents, extreme heat, and atmospheric corrosion.
