GEN-2 9MM BOLT CARRIER GROUP FOR GLOCK® & COLT® STYLE LOWER Reviews & Ratings

Purpose-built for 9mm AR-15 pistol caliber carbines, Faxon Firearm’s Generation 2 PCC blow-back carriers keep the features of their well-loved first BCG with modern improvements. Faxon maintain the dual COLT/GLOCK compatible geometry, user-removable weight and full-auto compatibility while adding new and welcome features. Faxon maintain a "ramped" bottom so any common trigger can be used - ideal for competitive shooters and plinkers alike.

The extractor has been upgraded to an AR-15 pivoted and sprung option. For ease of disassembly, a standard firing pin cotter pin is used, and to ensure long-life, the carrier key is separate from the charging surface ensuring that the carrier stands up to any vigorous action - no sheared keys! A stronger firing pin rounds out the new changes.

Nice bolt

I put this in a Spikes upper with Faxon barrel. Several hundred rounds through it now with no problems. It functions well and locks back on an empty mag.

Runs Great!

Got a Faxon 9mm BCG and 8 barrel for an EPC9 build. Everything went together flawlessly. Ive named it Mikey, because itll eat anything! 115s to 147 flat nose, flex tips, suppressed/ unsuppressed, it doesnt matter. BCG runs fine with a milspec trigger and slide locks back on last round using Glock mags. Barrel is more accurate at 25 yds. than my red dot & eyes. Highly recommend.

Runs well

An excellent and beautiful bolt carrier

I used this 9mm bolt carrier assembly in a 8 pistol build. Its on a pistol lower using a PCC-weight buffer, with a Stern Defense Glock magwell adapter, and a Fostech Echo II Sport trigger. It's a wonderfully fun setup with optional meme mode, and I absolutely run the hell out of the Echo trigger if I use it, which requires a quality, full-auto BC. I have had nothing but reliable function from this Faxon BC, in both semi-auto and Echo. FDE coating is slick and easily cleanable, and shows no signs of abnormal wear. I own a few various Faxon components and they all seem to be of very high quality.

Solved Extraction Problems, Great Produc

This solved extraction problems that I was encountering in both of my 9mm Ar-15 pistol builds. The Faxon bolt is superior in every way that matters to the Colt 9mm bolt that I was using, previously.

BCG Purchase

Appears to be in good working order and will hopefully work with the rest of the components in my AR 9 build.

Logo change.

First I would like to commend brownells on there exceptional shipping and handling times during the holiday season. Second I would like to make it aware for the future customers that these BCGs no longer include any faxon markings, labels or emblems as well as no serial or identification number. I found this out first hand and have confirmed this information through brownells customer service firearms team. The BCG is now simply marked with a laser cut picture depicting a brownells ram. Third the BCG came nicely packaged but suffered some light marring at some point. I will try to capture this in the photographs.
