Most Helpful Positive Review Best Lightweight BCG Design
I'm very impressed with this BCG it weighed about 8.5 oz on my scale. The nitride finish looks great, no blemishes. This BCG also completely covers the ejection port door. Many lightweight BCG designs contain skeletonizations that could easily allow debris into the action. Not this one.
Most Helpful Negative Review Would be nice if staked properly
The BCG works fine and has a nice coating, but Faxon refuses to properly stake their gas keys. I bought one which Faxon replaced under warranty due to almost non-existent staking. The next one they sent, which they inspected prior to shipping, wasn’t much better. I bought the Faxon because it was...

Great lightweight BCG

by Mixmasterm10, Verified Owner from CO, United States Written on December 25, 2025
I bought the first one with little knowledge of quality and durability. I’ve used it in my gamer gun for many competitions with absolutely no issues. I bought my second one to duplicate my gamer set-up and use it in conjunction with Unrivaled competition buffer system. I’m extremely happy with the product!!

Very disappointing

by Tokey, Verified Owner from LA, United States Written on October 17, 2025
Bought this bcg and a ultradyne adjustable gas block. Will not stay open after last round no matter how I adjust gas. Put in 2 other bcg's and they stay open after last round just fine.

fit and finish

by THop, Verified Owner from OH, United States Written on April 6, 2025
Haven't yet been out to operate with this item, so can not give input on its functionality. But, given other Faxon items that I've purchased in the past, i anticipate it will at least meet my expectations.

I can input, that the machining of this item, along with the finish & bolt movement, are well done.

Anxious to put it through its paces.

Helped reduced felt recoil

by Mario, Verified Owner from TX, United States Written on March 16, 2025
I ran this bolt carrier with an H2 buffer (JP SCS) and a non adjustable gas block. This set up helped reduce almost all the recoil as the system had regulated all the mass. You will have to adjust the spring to increase the latency so you’re not slamming the bolt back but otherwise, great set up. Also no problems with ejections since I have already put about 1,500 rounds of Winchester targets through it.
Pros:
  • good all round
  • light but solid
Cons:
  • Coating wears off fast
Would recommend: Yes

Fantastic BCG

by SteelCity65, Verified Owner from VA, United States Written on October 12, 2024
I was looking for a lightweight BCG for a pistol build, and this is the one you want! A lot of other options do not have compatibility with forward assist, but this one does, and it works. I have put a few hundred rounds through it so far, and it just wipes clean. It is also keeping up with binary fire. Strongly recommend.
Pros:
  • Lightweight
  • durable
  • Easy to clean
  • Full auto rated
  • forward assist capable
Cons:
  • None
Would recommend: Yes

Great BCG for 300BLK

by Psidon, Verified Owner from NM, United States Written on September 7, 2024
Was having issues getting my 8" Aero to cycle with subs, even suppressed. This BCG made all the difference. Zero FTEs or FTLs with numerous brands of ammo.
Best Used for:
  • ar pistol
  • Subsonic 300BLK
Would recommend: Yes

Perfect for lightweight build

by Isaac Kim, Verified Owner from CA, United States Written on April 11, 2024
Shot 500 rds through with my aero build. Haven’t had any issues. Looks great with quality and precision. Shaves off a smidge for a light weight build for a good price.

Nice and light

by Saplg8, Verified Owner from AZ, United States Written on October 12, 2023
I've put about 300 rounds through it. So I'm not sure if I can give you an accurate review. But it has not malfunctioned once.
Like it so far
