Nickel Boron Bolt
This is the second one of these I have bought for a rifle build. I have used this BCG in two day fighting rifle classes with both brass & steel cases. The BCG did not disappoint. With more then a few thousand rounds cycled, I have not had any issues. And yes, I do lube the bolt.

Nickel Boron BCG
All the places I usually get AR parts from were completely out of BCG’s and then I found Surplus Ammo. I have never heard anything about them, yet they had BCG’s in stock for decent prices. I tried out ordering the nickel boron BCG with a 223 bolt and waited to be disappointed. I received it in about a week and tried it out, and I was surprised that this was a quality part. The gas key was properly staked, fit was excellent, functioned flawlessly, and the finish makes cleaning a breeze. I will be recommending surplus Ammo to anyone I can.

BCG
Shipping was slow but I think I ordered during the move. Haven’t used in my build yet. Overall product looks good. Will update more after my build.
Merry Christmas -
This is a good product for the price.
First try for a NICKEL BORON BCG with the bolt not coated. It works great. I recommend it.
