Excellent performance.

by Ethan C., Gear Expert from IL, United States Written on March 26, 2018
I used this bolt carrier group in a 9.5" barrel AR pistol build with a Faxon 9mm SAAMI barrel, it ran flawlessly and cycled quickly and smoothly. This was Colt-SMG 9mm build rather than a Glock magazine build, however this will work for Glock magazine 9mm builds as well. I used a 9mm carbine buffer with a JP Enterprises .308 buffer spring, recoil was negligible allowing for extremely rapid repeated shots, all placed within an inch at 75 feet (the max distance possible at the range I was at) using flip up iron sights. I'm a left-hand shooter and even without a 9mm ejection port dust cover, casings did not hit me, they were ejected straight to the side. Very happy with this bolt carrier group.
Most Helpful Positive Review Very nice!
Faxon always makes quality products. I've began using all of their BCG's and barrels. I highly recommend any of their products. Shipping on this BCG was fast as they did have it in stock. Review must be 200 characters.......seriously.
Most Helpful Negative Review Incomplete assembly
It appears the roll pin at the rear of the bolt carrier was not installed . I would expect this from a Harley Davidson factory but not from faxon . Maybe it fell out in the mail packaging was very poorly done .

by HG, Verified Owner from AZ, United States Written on October 22, 2025

Thanks O.P. for the great pricing and quick shipping.

  • None

Pros:
  • easy to install
  • Removable Weight
Cons:
  • None
Best Used for:
  • AR9
Would recommend: Yes

Faxon Gen 2 9mm. Awesome

by Oscar, Verified Owner from AZ, United States Written on April 14, 2024
My set up is Aero 8.3" 9mm upper, PSA 556 lower, Armaspec 9mm captured spring, and Endomags. Ive had absolutely zero failures and the last round bolt open worked every time. The nitride Faxon bcg is very easy to clean. I highly recommend the Faxon Gen 2 PCC BCG.

Runs Great!

by Elusive, Verified Owner from OR, United States Written on April 13, 2024
Running this in my Aero EPC-9 build. Saw that the EPC was having some cycling issues, went with the Faxon bolt and a 8.1 oz buffer. Runs great! No malfunctions so far, roughly 1000 rounds. This is my second Faxon bolt. Never had any issues, great product as always
