Overall the bolt is awesome!! Im using 1 wth another bolt carrier and it's been great! I also have the full Sagrs NIb bcg running in my suppressed 13.9p/weld. I will be buying more of these bolts to replace my other bolts and keep them as extras. Only reason I didn't pick 5stars was cuz my first bolt that arrived had extractor issues, HOWEVER my customer service experience was exceptional and my new bolt was sent out almost immediately.. This is the ONLY bcg and bolts I will be buying in the future..

I used the NIB-X Coated Relia-Bolt in my first .300BLK build. I found it to be excellent in all categories! The fit is perfect, the finish is super lubricious and easy to clean, and most importantly the function is flawless! I plan to upgrade all my ARs to the Sharps Relia-bolt! If they made a Nib-X coated full BCG in 6.5 Grendel type 2, that would be going in my current builds! Hint hint.

Very good bolt. Never fails I’ll be ordering again from this company. It came in on time to.

My bolt carrier group has run flawlessly 1500 rounds

Meets all the qualifications that they claim. Very happy with performance.
