AR-9 Pistol Lower Build Kit w/ SBA3 Brace

Description

The affordable way to finish your AR-9 pistol build. Now with a brace!

Need all the lower parts for your AR-9 receiver? Grab this lower build kit! It includes the necessary 9mm buffer, a tube, recoil spring, and LPK for assembling your 9mm AR lower receiver. It also includes the original AR-type pistol brace, the adjustable SBA3 from SB Tactical! Fits standard buffer tubes.

Lower Parts Kit

This LPK features a mil-spec hammer and trigger, with standard pins and springs to provide a single-stage trigger pull of approximately 4.5 pounds. It offers a crisp, clean break and reset.

NOTE: The AR-9 uses the same lower parts kit components as the AR-15. But some parts, like the 9mm-specific magazine catch, come with the lower receiver itself.

Therefor, some components provided in this lower build kit will not be required for final assembly. You will have leftover parts, and that’s OK!

Buffer Kit

The buffer components in this lower build kit are 100% mil-spec, ensuring compatibility with virtually all modern AR-9 lower receivers (whether forged or billet).
