Mercury Precision 16.5" 5.56 NATO, Government Profile, Nitride, Mid Gas


Mercury Precision "Satellite" 5.56x45mm 16.5" QPQ Nitride Government Profile AR-15 Barrel

The 5.56 NATO cartridge is the backbone of the American Military and the even larger American firearm community. Why skimp out on your barrel when you can set yourself up with the best barrel at the best price you'll find out there? The Mercury Precision barrel is made out of 4150 Chrome Moly Vanadium and finished with a nitride solution that will keep your barrel not only looks amazing but will stand up against any rust and adverse conditions you would ever throw at it! This barrel also boasts a 1:7T rate barrel, which is the same exact style as the M4 barrels that the US military uses. The barrel uses a mid-length gas system which blends perfectly the compact carbine system with the super reliable rifle length gas system. The barrel also hosts a .750 channel for gas blocks.

Being 16.5" this barrel also boasts an effective muzzle velocity of 2,927 ft/s using M855, this is perfect for effective target shooting, penetration of several body armor (for those tricky range days that are a little extra spicy), and the perfect length to avoid issues with NFA regulations. The 1/2x28 thread pitch also allows for a wide variety of muzzle devices to be used on this barrel, from standard A2 flash hiders, through compensators for those competing in shooting competitions, and even suppressor adapters like Surefire, SilencerCo, and Dead Air to name a few!

The free-float barrel not only keeps your barrel cooled down compared to the original drop-in styles but opens up the opportunity to use any of the huge selection of handguards that allow for your own unique and custom take on the AR-15!

So stop wondering what you should do, and get yourself this barrel to start off your build!
