Does not run smoothly.

by Seferino Hernandez, Verified Owner from ND, United States Written on November 2, 2025
The BC feels like it’s stuck. I have the right Gas block, gas tube, buffer tube, etc. my rounds would not cycle (eject and reload.) I replaced the bolt carrier for with another one and that solved the issue. I’m upset due to being out $170…..
Pros:
  • None

nemo bcg for the new build

by B from SoCal, from CA, United States Written on November 1, 2024
Absolutely love this for my new build that’s used for both 5.56 and 300blk!
Just got back from the range and it does exactly what I’d expect! It was flawless with both uppers

Nemo BCG for my new build.

by psyk00diver, Verified Owner from OK, United States Written on March 7, 2024
When I saw that Optics Planet was offering a .556 BCG from Nemo Arms, it was a no-brainer to pick one up. Nemo's stuff is always spot on. The finish was perfectly coated. I can't wait to get it out on the range and run it like a scolded dog!
Pros:
  • Coating looks clean and amazing
  • bougie in the good way.
  • perfect upgrade to any mil spec AR 15
Cons:
  • None
Would recommend: Yes
