This Bolt carrier group was a great purchase and affordable for the results. It’s constructed beautifully and is super heavy duty. The BCG operates smoothly and to boot is super good looking in my new 300 BLK.

I have over 400 rounds with it and yea…. flawlessly cycled every time. Just put this in my RRA Lar-15. The stock BCG was smooth already. This is smoother and seems faster? Cleaning was a snap. Most the crud just wiped off, with the remaining just a bit of elbow grease. Gotta say, it looks great in there. Saved the hammer for another build so no review on that. RRA 2 stage trigger. Love it.

This is a semi bolt. I used it in my RRA LAR ar15 which has a very nice full BCG. This bolt, as it should, has less felt recoil and seems a bit faster. I didn't use the hammer as the RRA came with a pretty good 2 stage. Where this bolt shines (pun intended) is maintenance. Clean up is a perverbeal snap. Most all of it (after 400 flawless rounds) whipped off. Some scraping here and there.

This has been a flawless BCG for me. The fit and finish is great and I have had no problems at the range. There have been zero FTF's. I purchased another for my next build. Easy to clean. Great product.
