But to enjoy all that performance, you need a quality 300 Blackout Rifle Kit, like these. Each one is configured to run all forms of 300 AAC Blackout, with high precision and utter reliability.
Why Our A300 Blackout Kits?
Not all AR-15s are created equal. With so many vendors and manufacturers flooding the market, it's tough to find a quality black rifle configuration that doesn't cut corners (or cost an arm and a leg). We partnered closely with OEM gunsmiths and cut out the middle men, ensuring our AR kits are affordable while providing mil-spec quality and truly great performance.
Here are just a few reasons why our kits are a great value:
- All barrels are forged from MIL-B-11595 E steel (4150 or Chromoly Vanadium)
- All stainless barrels forged from Crucible 416R steel, offering sub-MOA accuracy
- All BCGs are M16 in profile with chrome lining and properly staked gas keys
- All stripped upper receivers forged from mil-spec 7075 T6 aluminum
- All buffer assemblies and lower parts kits are mil-spec in fit and finish
- All barreled uppers are test-fired to ensure proper assembly
In addition to top-tier specs, we selected various lightweight and free-float handguards that provide greater accuracy with plenty of "rail" estate for all your accessories. Coupled with your barreled upper, our AR-15 kits provide the perfect balance of pre-assembled parts with the opportunity to customize your new rifle as soon as your assemble.
