Description

16” Carbine-Length Rifle Kit w/ Lightweight 13.5” Keymod Handguard

Got your lower assembly put together, and want to finish your build strong?  Our black-barreled keymod upper assembly lets you do just that.  It starts with a 16″ black nitride coated M4-profiled barrel chambered in .223 Wylde.  This means you get a barrel that’s made to afford the shooter greater accuracy at the range as well as the ability to fire both .223 and 5.56mm NATO rounds with no risk of blowing your rifle in half.  Over the barrel, we add a 13.5″ lightweight keymod handguard.  Everything else about the upper assembly is standard right down to the flat top upper.  This means you can add whatever picatinny or keymod-based attachments to its rails that you want:  vertical grips, tac lights, lasers, a cup holder…scratch that last one.  The point is, you can customize whatever you want or keep it stock for straight up reliability and a super light piece of machinery to tote to the range.

AR 15 Upper Assembly Details (Expanded):

Barrel: 16″ carbine-length chrome moly vanadium steel, chambered in .223 Wylde, 1:7 twist rate, .750″ low-profile gas block, 13.5″ free-float keymod handguard, with an A2 “birdcage” flash hider.

Upper Receiver Assembly: Forged from 7075 T6 aluminum, hard-coat anodized in black for durability, features M4 feed ramps, and are made in the USA.

Bolt Carrier Group: The bolt carrier is made from 9310 steel and has a staked gas key and black nitride finish. The bolt itself comes complete with an extractor spring and O-ring insert.  It accepts .223 Wylde, 5.56mm, and .300BLK calibers (though you should NEVER attempt to use a caliber for which your rifle is not chambered), and is magnetic particle inspected.

Charging Handle: standard size, made from 6061 aluminum.

Please note: This build kit requires that the builder complete the 80% lower receiver themselves, but that’s the rewarding part of the experience (and the only way to build your own AR-15 without the need of an FFL transfer or serialization).

No FFL required Made in the USA Lifetime Warranty
