The FailZero 9mm AR9 Bolt Carrier Group (BCG) is fully assembled and can fit into most 9mm AR platform rifles and pistols and is compatible with Colt and Glock style magazines. This 9mm BCG is constructed from 8620 steel and features a staked gas key which acts as a carrier guide to keep the BCG oriented correctly since it is a blowback design. The firing pin is chrome plated for added durability and every other component is salt bath Nitride finished for increased hardness and lubricity making it wear resistant and easy to clean. The 5.56 extractor is heavy duty and helps keep your 9mm AR-15 running reliably. Upgrade your 9mm AR-15 with the FailZero AR9 BCG today!

Runs Great In AERO EPC-9

by -

No complaints! Well - a tiny one if I wanna get picky: the fancy logo is 85% hidden by Aero's upper, but I really don't care. I just want to make sure OG LARPers know this may happen.

Fail zero works!

by -

I was having a problem with my rifle tried different weights off of buffers. Tried the coin trick for the spring in the buffer tube. Tried different mags. Seven different makes of mags! Was ready to part the rifle out. Seen the fail zero and ordered one. And that’s what I got zero fails!! Rifle cycles great now and is a blast to shoot. I will buy this product again and if my friends are having any issues tell them about this product! This product means what it says. Thanks for ending my frustration with this rifle!!

Best 9mm BCG

by -

While building an Aero Precision EPC-9 I have installed a Geissele trigger and initially purchased the Aero BCG. The Aero BCG is incompatible with most triggers. This Fail Zero BCG is much nicer, machined out of one piece with a pinned in rear Wright the way it should be made and much different than Aeros poor design. I have also removed the rear weight and installed a Law Tactical folder. I am running an AR Stoner 11oz buffer, KAK Law PCC adapter and a Strike Industries flat wire AR15 carbine spring (not 308). This setup is amazing! Excellent BCG!

If your building an AR9 you know the buffer weight, BCG and ability to use a law folder/geissele triggers are all unicorns, this BCG does it all!
