Finally an amazing bcg - Aero Precision AR15 5.56mm Bolt Carrier Group

I love Aero especially after ordering this nib bcg. It is the first bcg I've owned that actually feels like it is great quality. The nib is really nicely polished, Surprisingly a lot of manufactures don't do this. and there are no lathe or machining marks on any of the surfaces. it truly feels like the peek of low friction and natural lubricity. I will be replacing all my other nitride and phosphate bcgs with the aero nib . prob one of the best upgrades that can be done for reliability and longevity.
