Most Helpful Positive Review Failzero bcg
Absolutely love this bolt. Optics planet gave me an amazing deal on this and got it to me in a timely manor. A little bit about myself, I worked 2 years in the armory at 29 palms while I was in the marine corps. So I feel like you can trust my advice when I say definitely pull the trigger on this bc...

Most Helpful Negative Review fail zero bold carrier
Shot nicely didn’t notice much of a difference. After about 40 rounds of shooting suppressed, the fail zero bcg is stained. Normal of course but after scrubbing and cleaning for 20 min it is still stained. Not a big deal but if your buying this for the look keep that in mind.

First Impressions

by Tangy, Verified Owner from CA, United States Written on January 18, 2024
One of the nicest BCG I've held with it's amazing finish. Not sure if this is by design but I can't do the flick the BCP down test like we do in the military. It feels like a click when you do it manually or it could possibly need some breaking in. Can't wait to try this out at the range and will update this review once that happens.

BCG review

by Nate, from MO, United States Written on January 24, 2020
This BCG is slick. If you have a forward assist like me, it will not be function able. other than that, this bolt is lighter and smoother than your average bcg. Although i have only sent around 4 to 500 rounds through it i can say that it is an improvement over the standard bolt. Cleanup is a breeze as well. No heat stains or early wear and tear.

Great BCG; fit and looks

by GJ, from OR, United States Written on January 16, 2020
I’ve not been able to shoot this yet as my build is not complete, but fit and finish are excellent. It’s very well made, the coating looks great and even and it fits perfectly in my upper. The coating feels very slick and after an initial clean-and-lube the carrier is almost hard to hold on to! Only reason for not giving 5 stars is because I have not shot it it so I can’t comment on its performance.

Best bcg in the game

by Robert Segura, from TX, United States Written on August 29, 2019
Fail zero has one of the best coatings on the market. Running with an h2 buffer, sprinco blue spring, and a superlative arms adjustable gas block in a 10.5 sbr. Runs like a champ. Had the Ar size bcg in Munich past build and wanted this one to tune the gas system for a softer shooting gun.
Pros:
  • Slick
Cons:
  • None
Best Used for:
  • Duty rifle
Would recommend: Yes
