This thing does exactly what its supposed to do . I have used it in my 5.56 and my 300 Black Out and has greatly reduce the gas in my face. Shooting both calibers with a Dead Air Nomad and the inside of my lower would be filthy until I started using this bolt carrier. This with a silencer central gas defeating charging handle everything is good ! So good I bought three.

This BCG works as advertised, but the selector began free spinning after a short time. I contacted the company, left a message, sent a Facebook message and email. I got a response via messenger but it took them a month to get me a new selector. When I got it, I swapped them out and the tolerances are much tighter now. I haven’t tested it out since but I imagine there won’t be issues.

Got this instead of the Gemtech, because you can adjust it inside the gun, and it has 4 different positions witch I like also, don’t have many rounds through it but it seems to work fine so far that’s why I couldn’t give it five stars because I just don’t know yet, but I seems to be high quality and at a reasonable price
The guy who loaded a 300blk in his 5.56 –
I bought this product about a year ago and I've put a couple hundred rounds through it since then. Not only has it worked flawlessly but it also eliminated the unpleasant over-gassing problems, improved reliability, and it slightly reduced felt recoil. The best part? When a 300blk cartridge found it's way into my magazine loaded with 5.56, the bolt was destroyed but the lower receiver survived and I was completely un-injured. I will be buying a replacement here soon.Works exceptionally well for 5.56 and 300blk but I don't recommend it for shooting 300blk in a 5.56

If you’re using a suppressor with your AR-15 thus us a MUST to have. It will reduce to totally eliminate back gas and tremendously reduce overall recoil which will greatly increase target acquisition on second shot!Highly recommended!

So far works as intended for 300 blackout no issues yet the adjustable feature is easy to use and is great for suppressors and subsonic ammo, shipped fast, and was well packaged will go to the range for further testing soon.
