Most Helpful Negative Review Fostech AR 15 Bolt Carrier Group Nickel Boron
See my previous revue. Received my returned/exchanged BCG yesterday. The quality is much better than the first one, no tool marks and no dings.

damaged gas key

by Small pen15, Verified Owner from LA, United States Written on December 1, 2024
Went to install the bolt carrier and found it was getting hung up on the gas tube. Upon inspection I found that the gas key was deformed and had scratches around the rim. I swapped the fostech out with 2 other carriers I had and they worked fine. Now I need to figure out how to change the gas key and stake the screws…other than that issue, the carrier, bolt and other small parts look great. The nickel finish is smooth
Pros:
  • good finish
Cons:
  • Damage from thhe factory
Best Used for:
  • Sending freedom down range
Would recommend: No

bolt carrier awsome

by ernie, Verified Owner from CA, United States Written on September 6, 2023
This bolt has a great finish on it. Super easy to clean. Fit well for my ar15 build. Runs really smooth inside the ar15. The bolt carrier came in goos packaging and came in light oil. This company is pretty good.

by Nate, Verified Owner from AR, United States Written on August 7, 2023
I haven’t used it yet but looks ok. There are some tool marks on certain spots but won’t hinder the form and function of the BCG. Other than that I don’t foresee any issues. The gas key looks staked properly.
Pros:
  • Looks nice
Cons:
  • None
Best Used for:
  • Pew pew

by Davis, Verified Owner from NC, United States Written on December 6, 2022

Fostech BCG, Nickel boron.

by Mark, from TX, United States Written on August 26, 2021
I bought the nickel boron one. It is great. I had bought one before and it worked excellent, clean and smooth. The second one I just bought is just as great. I think this one is going to be the BCG for all my builds.

Also, I like the stainless "color" as it is easier to see when it is dirty and keep it clean.
Pros:
  • Smooth and clean
Cons:
  • None
Best Used for:
  • anything
Would recommend: Yes

Ni boron bolt

by Thomas Castellano, Verified Owner from GA, United States Written on July 9, 2021
I got the boron bolt. It looks pretty but I can't get tell you how it shoots. It won't feed the rounds for some reason. The one round I got chambered... The firing pin didn't hit.. no pew. I broke the thing down and rebuilt it. I should have returned it but I'm impatient and like to do things on my own. I'll update if it shoots.
Pros:
  • It looks nice.
Cons:
  • Won't feed ammo
  • Won't fire
Best Used for:
  • Paperweight
  • Heavy fishing sinker
Would recommend: No
