Aero Precision VG6 Epsilon 556 Muzzle Brake

Aero Precision VG6 Epsilon 556 Muzzle Brake

The Aero Precision VG6 EPSILON 556 is the pinnacle of AR15 muzzle devices. Utilizing many of the same muzzle brake/compensating features as the GAMMA 556, the EPSILON 556 also includes additional flash hiding characteristics. Extended flash hiding prongs and no ports at the 12 o’clock positions allow uninhibited view from flash through optics or sights. The difference in porting is also noticed on the underside of the device where it has 6 valve holes to allow the fastest gasses reaching the second chamber to exit. This creates very soft low energy recoil that allows for absolute control.

Features:

  • Material: 17-4ph® Heat Treated Stainless Steel
  • Finish: BLACKNITRIDE™
  • Surface Hardness: 68RC
  • Caliber: 5.56mm/.223 Rem. only
  • Thread: 1/2-28 RH
  • Weight: 2.5oz
  • Includes crush washer

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.
