AR 15 Rifle Upper Assembly (16" Stainless Barrel & 13.5" M-Lok Handguard) - 1:8 Twist



Assembling an 80% rifle build kit is one of the fastest and most cost-effective ways to make yourself a proud new owner of an AR-15 rifle without registration, serialization, or an FFL purchase.

The lightweight 13.5″ M-Lok free-float rail allows scopes, tactical lights, hand grips, and many other accessories to be attached to your rifle quickly and efficiently. The AR-15 rile kit is an ideal weekend project for build kit beginners. By the end of the weekend, you’ll ensure your family is safe with a finished, unserialized AR-15 rifle.


Upper Receiver Assembly: This upper receiver is Forged from 7075 T6 aluminum and is hard coat anodized black for durability. Featuring M4 feedramp cuts and T-marks, these upper receivers are made in the USA. Included in this AR-15 Upper Assembly is:

  • Barrel – 16” Carbine-length Stainless
  • .223 Wylde
  • 1:8 Twist
  • Upper Receiver – Forged 7075 Aluminum
  • Bolt Carrier Group
  • Gas Tube
  • Gas Block
  • Flash Suppressor
  • Charging Handle

This is a true “plug-and-play” upper assembly that requires no additional engineering or manufacturing except slapping it onto your lower receiver.

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