Building a tried and true M4 platform (save for the .300BLK caliber), a perfect clone of the venerable USGI rifle has never been easier or more affordable.

At just under $1,000, this .300 AAC blackout rifle build kit gets you everything you’d find on a military-issue M4: polished feed ramps, an M16 bolt carrier group with a Carpenter 158 bolt, government profile, chrome moly barrel, A2 front sight post with pistol length pre-installed gas system, A2 birdcage flash hider, forged upper receiver, and a mil-spec phosphate hard coat finish.

A mil-spec lower parts kit accompanies a six-position buttstock and carbine buffer system and a quality 80% lower, everything needed to finish your at-home build! This kit is 100% legal to ship straight to your front door, no FFL transfer or paperwork needed. Nothing in this kit is considered a firearm by any state or federal law. If you were looking for the most affordable way to build a quality M4 platform rifle, you’ve found it.

Need a California-Compliant Build Kit? Follow These 4 Steps!

1. Choose “CA-Compliant Lower Parts Kit” in the Lower Parts Kit dropdown.

2. Choose the “No Lower Receiver” option for the 80% Lower Receiver dropdown.

3. Select/Click “Add to Build”.

4. Head here to purchase a California-compliant 80% lower receiver

Please note: This AR-15 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).
