Ratings & Reviews

Outstanding BCG; works flawlessly; matches Aero Precision FDE upper/lower set reasonably well. BCM's quality and Primary Arms's customer service are a great combination.

Put this in an all black AR and it just look awesome. Functions perfectly. Yet another quality product from BCM.
FDE finish wearing rapidly.
by Vincent -
Highly impressed at first but already seeing a lot of wear on the finish. After only 100 rounds I'm disappointed.
Good to go

We all know BCM is well known because of their BCG's. If you've worked in an industry that has stringent QC, you understand why it's important and BCM is particularly good at it. Function is perfect as expected. The IonBond coating is..meh. I would've grabbed a regular phosphate BCM BCG if I had handled this one prior to getting it.
BCM, the gold standard of commercial AR’s

BCM has been the golden standard! Love this BCG. Hasn’t given me a single issue yet! Just be mindful the “FDE” is more of a bronze, which I like better actually. 5 stars!

I recently purchased this bolt and have not yet fired it. I took it out of the packaging to mock up my new build this weekend and examined this bolt. The outside of the bolt is machined perfectly, however the inner portion looks like it was machined with a dull bit. It is rough to the touch with a divot in the material aswell. This is not really what I was expecting from a BCM bolt.
