sharps bolt carrier group January 18, 2018
Reviewer: Joseph Boniface from Wayne, NJ United States  
great bolt carrier, i was one of the first to order the first batch of relia-bolts, never had an issue, and was pleased with the lifetime warranty. knew i had to have the balanced bolt carrier, very smooth and very easy to clean. the S-7 tool steel is bonus, for the price of a decent milspec bolt carrier why not get this one?
