No issues, always my bolt to use when troubleshooting builds because it has never had a single issue. O-ring comes installed since that isn’t in the description. The best machining I’ve seen on any BCG and really any AR parts for that matter. Carbon just wipes off with a cloth, no scrubbing or chiseling that hard carbon we have all experienced. I guess it has to do with the lubricity of the finish. Feels so smooth it prolly doesn’t need oil. Tho I still give her some of course. The last 3 bcgs I bought were sharps and I’d have a hard time using anything else now.

I have two and they have never failed. About to add a third.

I have installed these in a number of rifles for family,friends,and customers. Never a problem. Don’t hesitate,buy with confidence.

Awesome bcg have 1000s of rounds on one and its had 0 issues. Will be buying another one and probably the only bcg ill ever buy again.

Purchased this SRC DLC BCG for my 8.00" 300BLK AR about a year ago.

I am currently finishing a new build *12.50" 300BLK*. I purchased another Sharps DLC BCG.

That should say everything.

Thanks Sharps Rifle Company.
