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!

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
