About this product

The AAC MPW SBR in .300 AAC Blackout is a compact, high-performance rifle built for precision and durability. Featuring a 12.5" nitrided 4150 barrel with a 1:7 twist, this model ensures exceptional accuracy and longevity, outperforming chrome-lined alternatives. The muzzle is threaded 5/8-24 and includes an AAC 51T BLACKOUT flash hider for reduced signature. A Knight's Armament URX 3.1 free-float rail provides a stable platform for accessories while maintaining accuracy.

This AAC MPW retains full 30-round capacity using standard AR-15 magazines, blending the power of .300 BLK with the ergonomics of a 5.56mm platform. The Geissele 2-stage trigger offers a crisp break, while the Magpul CTR stock enhances stability. The nickel-boron EXO-coated bolt carrier group delivers reduced friction and superior corrosion resistance, backed by a Carpenter 158 bolt for reliability under heavy use.

Built with premium components, this SBR is designed for demanding applications where compact size, power, and durability are critical.
