Spikes is always a good option by Flyingmark, Verified Owner, September 19, 2023
I’ve run about 3,000 rounds through the lightened (10.5 oz) BcG and I’m not showing an access of wear and tear. The only real downside to this thing is that the holes they used to lighten it are a pain to clean. Let’s just get this out of the way as ...

Nice Bolt Carrier Group by kentw218, Verified Owner, February 18, 2025
Product arrived quick and seems to be very high quality. The picture makes it look like its stainless or has a brushed finish, but the BCG is black. Just in case anyone was a little confused by the picture.

It definitely has a 9310 bolt not a c158 but I don't care. by Willie Springs, Verified Owner, July 29, 2021
Great fast service like always from Optics planet. The Spikes BCG looks great. Some people are upset because they were expecting a C158 bolt and I can understand that since they're supposed to be mil spec. But it doesn't matter to me. 9310 when heat ...
