Rearden SPB Muzzle Brake .50 Caliber 5/8-24 Black

Rearden SPB Muzzle Brake Features The Rearden SPB is machined from 17-4 PH stainless steel and heat treated to H900 giving it the strength to handle repeated suppressor mounting and dismounting without losing precision. Its square shoulder design is built specifically to index against Plan B and Atlas type suppressor mounts so alignment stays consistent every time a can goes on or off. The .50 caliber bore and 5/8x24 threads make it a direct fit for barrels machined to that thread pitch and Rearden recommends torquing the brake to 15 to 25 ft lbs with thread locker for a secure repeatable mount. An Atlas adapter interface with approximately 1.050 of overrun is built in while the Atlas XL adapter interface has no overrun at all. The Black Nitride finish gives the SPB a 67 HRC surface hardness a treatment that resists wear from repeated suppressor attachment while helping the mating surfaces seal more tightly against each other. Shims are included with the kit to fine tune baffle strike clearance and timing though they are not included with the SR25/M110 or 11/16x24 variants. At 1.73 long and just 2.3 oz the brake adds negligible length or weight to a host rifle while still providing a secure foundation for a suppressor. The Rearden SPB is for sale at ARMSAGORA for shooters who want a precision direct thread muzzle device built around the Plan B mounting standard.
