Very well pleased with this product, quality was as expected for a Spikes Tactical item. Received from Buds very quickly, packaging was excellent as was Buds price. I will be making more purchases from Buds in the future.

Recieved the bcg after ordering...the carrier would not even slide into the upper receiver even without the bolt or cam pin ....I contacted spikes...they sent me a shipping label and a brand new bcg

Bought this to complete a 300 Blackout build I was doing and Buds was out of the one I really wanted but this one works just fine. Actually going to purchase another to replace the stock one in my Ruger AR 556.

This is the worst piece I have ever used. Turned my Anderson upper into a single shot. DPMS Bolt works perfect. AR Stoner bolt works without a hitch. Bone stock Ruger bolt not a failure. Spike bolt- Bang Jamb- Bang Jamb- Bang Bang-jamb I contacted Spike no response back. NEVER WILL I EVER purchase any thing with Spikes name on it Ever again!!!! But Buds is the GREATEST over 40 orders not a single issue and shipped promptly Thanks Buds Gunshop Spike GO JUMP IN THE DEEPEST LAKE

I ordered one for my Aeroprecision upper, they are about as good as it gets. I plan on ordering another just for a backup or a possible build.
