Perfect fit to my 300 Blackout build. Solid craftsmanship. Would definitely buy again for any other AR build!

I have 2. Never a hiccup. DLC makes for easy cleaning and helps make everything slide smoothly. Highly recommend.

This is a great quality product. I now have two of them.

I was very happy with the first unit. I did buy a second one. Great quality.

This is the second bolt carrier group I purchased and have been very pleased with the finish and quality of the product. Highly recommended
