Took a chance on this bcg & glad I did. Very well machined. No tooling marks, swirls or burrs. Has a real slick profile to it. The nitride treatment is highly polished & looks like glass. After 300 rounds I wiped it off with some clp & it looks like new. Gas key is properly staked. Been 100% reliable. Hard to beat for under $120.

I used the ALPHA premium bolt carrier group on my latest build and it appears to be beautifully made. Great fit and finish. Can't beat this BCG at this price anywhere. As always OPTICSPLANET has great service even during the current pandemic panic.

Bought this bcg on a friend’s recommendation and glad I did. Ran in multiple ar’s flawless. The machining is top notch. The nitride treatment is as smooth as glass. Super easy to clean. I’ve always ran with “high end” name brand bolt carrier groups in the past but now I’ll stick with these. Highly recommend

Very impressed on the finish and quality of the BCG. Smooth action and easy to clean. Ran about 500 rounds and not even a mark on the bolt face or lugs and extractor. Spits out brass as well as steel ammo with no issues at all.

Glad i bought this. Super good quality and finish. Alpha Shooting Sports v2 bcg is very reliable and property inspected. Very satisfied. This bolt carrier group is as good as any Aero, Daniel Defense or any high end bcg without the over exaggerated price. Ill be buying this bcg for my next build.Full size direct impingement too. rated full auto M16 or for AR15 is a plus.
