Surefire 7.62mm Muzzle Brake/Suppressor Adapter - 5/8-24 Threads

Surefire 7.62mm Muzzle Brake/Suppressor Adapter - 5/8-24 Threads

Precision machined from stainless steel barstock, the SureFire SFMB-762-5/8-24 muzzle brake greatly reduces both recoil impulse and muzzle rise. The SFMB-762-5/8-24 also serves as a rock-solid mounting adapter for SureFire SOCOM Series 7.62 mm Fast-Attach® suppressors, the SOCOM762-RC model having recently won the Mk13 .300 Win-Mag sniper rifle contract award with the US Special Operations Command in the most extensive and rigorous suppressor testing ever conducted.

All SureFire SOCOM Series muzzle brakes have blind pilot holes at the 3 and 9 o’clock position to enable fine-tuning of recoil characteristics for individual shooting styles or ammunition characteristics. They also have blind pilot holes at the 6 o’clock position to enable indexing the adapter at bottom dead center, and to pin-and-weld on short-barreled rifles. All that is required is a basic hand drill and appropriate drill bits.

FITS: Armalite AR-10, DPMS LR308, and 7.62 rifles with 5/8-24 muzzle threads

The revolutionary SureFire WARCOMP-556-1/2-28 flash hider, which fits M4/M16 weapons and variants with 1/2-28 muzzle threads, is the world’s most shootable flash hider.

It virtually eliminates muzzle rise, which enhances monitoring of target reaction and staying on target for faster follow-up shots. It serves as a rock-solid mounting adapter for all SureFire SOCOM Series 5.56mm Fast-Attach suppressors. Multiple bearing surfaces provide suppressor alignment and prevent tines from ringing inside suppressor. Precision machined from US mill-certified heat-treated stainless steel bar stock.

AR-15 Upper Receivers

Find the Upper Receiver Parts You Need for your AR-15 Gun

Customize or begin building sooner with our AR-15 Upper Receivers. We have receivers boasting hard chrome-lined chambers and bores that deliver exceptional endurance and easier maintenance. Choose from a fast 1:7 twist or the popular 1:9 rate in our selection of AR-15 upper receivers. Top names in receiver manufacturing are here, including Rock River Arms, CMMG, and ArmaLite. These makers emphasize testing prior to shipment for your satisfaction. CMMG conducts magnetic particle testing on its barrels, a process which reveals tiny flaws. Order a Carbine Upper Receiver with M4 feed ramps and Bird Cage flash suppressor from this manufacturer.

Get the Rifle You Really Want with AR-15 Upper Receiver Parts

Make a match rifle or a versatile hunting firearm with AR-15 upper receiver parts. The AR15’s modular structure allows you to modify its design to meet your aspirations. Find a flat top so you can reconfigure as needed. We carry an M4 version of the AR15 carbine – its flat top provides a range of sighting options. Many of our AR-15 upper receiver parts are made from higher grade, mil-spec steel and work with existing mil-spec lowers. We’re also your superlative source for AR 15 parts sold individually, from charging handle assemblies to sling mounts.

AR-15 Upper Receiver Assembly Ensures Components Coincide

When you want the complete package, we’re here with assemblies! You can opt for an AR-15 Upper Receiver Assembly featuring a 16-inch barrel and a 1:9 twist, paired with a flash suppressor, mount, bolt assembly and charging handle. A dedicated bolt to match the upper assembly is important to the workings of your AR-15. You’ll also benefit from a handle matched to your barrel. Choose AR-15 upper receiver assemblies backed by precision manufacturing to add to your rifle or when building a firearm from square one.
