Awesome buffer kit!! - Angstadt Arms AR-15 9mm 5.4 oz Carbine Buffer Assembly w/ Carbine Buffer Spring, 9mm Buffer Spacer

Worked well with the Angstadt setup! Built the gun exactly as is sold complete by Angstadt with all factory components, no issues whatsoever cycling with 500 rounds down range. Can’t go wrong with anything Angstadt, quality parts all the way! So if your needing a quality part for ur ar9 build, try this spring out, comes with spacer an buffer.
