Spikes .308 BCG by WarPoet05, Verified Owner, June 8, 2023
Another solid product from Spike's Tactical. The nickel boron coating is flawless and the gas key is properly staked. All-in-all, the BCG is premium quality. I've put several hundred rounds through it without any issues. Buy with confidence.

Spikes Tactical 308 NB BCG by Mome, May 29, 2020
I purchased the spikes tactical 308 NB BCG for my ar10 built. Very nice quality part. Fits like a glove. I like seeing the spider logo when the dust cover flips open. The bolt is smooth and easy to clean. It is very heavy duty.

Great product by Jamie, Verified Owner, January 3, 2026
Arguably the best BCG out there. Well built no flaws. This BCG just runs with no issues. I have two ar 15s that are spikes tactical and they both run great. The AR 10 is no different will definitely buy again
