Robust. Effective. Efficient. Why screw around with “complicated” when it comes to your AR? This build kit brings you one of the most efficient builds in our catalog. This black rifle kit gets you a solid base for a rifle that you can then use as is, or modify by adding accessories (light, laser, vertical grip, whatever) onto the included M-Lok handguard. Whether you subscribe to the KISS principle or go all out, this rifle will serve your needs and then some.
The upper in this kit ships with a 16″ parkerized barrel and 15″ free-floating M-Lok handguard. You also get a quality lower parts kit with a smooth trigger. Fabricate or buy a stripped reciever for final assembly, then hit the range.
