BCA bolt carrier group
Received item in relatively short amount of time especially since the package had to travel cross country. BCG is good quality and finish is nice, especially for the price.

Great part of my latest build
All you need to convert your ar15 to ar45 is a new barrel & bolt.

The Bear Creek Arsenal bolt carrier group seems to be of good quality craftsmanship. For the price, I had to try it.
