Description

If you’ve done the work so far of milling and drilling your 80% lower and assembling it all into the bottom half of your AR-15 (or if you just bought it already assembled, ya cheater), then add this upper assembly to your build to finish it off!

This AR-15 upper assembly features a lightweight 13.5″ M-Lok free-float handguard.  In addition to its top rail, the handguard has a row of M-Lok space on the bottom and one on each side a well, which affords you a ton of space to mount tac lights, lasers, forward and vertical grips, a cheese grater, or whatever else you can think of.  Mount this upper assembly to your lower assembly, and all you’ll have left to do is pick out your favorite backup sights and throw ‘em up on top.  And the best part is, it’s chambered in .223 Wylde, which means you can safely fire both .223 and 5.56mm NATO rounds!

AR 15 Upper Assembly Details (Expanded):

Barrel: 16″ carbine-length stainless steel, chambered in .223 Wylde, 1:7 twist rate, .750″ low-profile gas block, 13.5″ free-float M-Lok 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).

Shot sub-MOA out of the box

Ammo prices are pretty much forever wonky so I wanted a .223 Wylde so I can reliably shoot 5.56 as well. Slapped this my 80 lower build and went straight to the range and managed under 1 MOA at 100 yards with both .223 and 5.56 factory loads, I went for the 1:7 twist in this barrel because it handles the most common 70-grain stuff with ease, the 416R steel is beautiful, rifling is nice and sharp, the M-lok is lightweight, you'll be pressed to find an upper that shoots this nicely with junk ammo anywhere else. Also props for the F/A bolt carrier, this thing can run and run.
