Description

Check out one of the earlier additions to our line of AR build kits  Configured in pistol length, this AR comes to you chambered in .300 AAC blackout.  We take a pre-built upper assembly with a 10.5″ stainless steel barrel and a 1:7 twist rate paired with a 10″ M-Lok handguard and pair it with all the necessary parts to end up with a working .300BLK firing AR pistol.

In addition to the pre-built upper receiver your choice of 80% lower, and a lower parts kit, this kit also features the Shockwave blade pistol stock kit, so you can keep your AR pistol legal.  You can finish this build kit off by adding either a set of backup sights or an optic of your choice, and mags and ammo of course.

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).

It is your responsibility to fully understand all applicable laws and regulations regarding purchase and ownership of uppers with a barrel length of less than 16″.
