Your bolt carrier group is one of the most critical parts of your build. Don't buy an imitation. This is the same BCG Spike’s uses on their builds. These complete bolt carrier groups come magnetic particle inspected and high pressure tested. The carrier is made from 8620 steel and the bolt from no. 158 carpenter steel or 9310 depending on supply. The gas key is properly staked, the extractor spring has been upgraded with an O-ring for increased tension, and all surfaces are MIL-SPEC heavy phosphate coated or internally chrome lined. The Spike's Tactical Spider Logo is engraved on the right side of the carrier to show through the ejection port. Assembled BCG weighs 11.6 oz.

Overloaded Ordering System

by

The Spikes products speak for themselves... Good Stuff. I want to comment on the Customer Service. When I clicked on the "BUY" button things went haywire. I did not know if my purchase went through or not. Seasonal overloaded... The folks at Primary Arms followed up in a business like manner and followed through on getting my order straightened out. The customer Service is what makes me a return customer. Merry Christmas 2013.Hobo

Spike's Tactial FA BCG: Good BCG

by

The Spike's Tactical full auto BCG seems to be a good-to-go product. Overall quality seems good--both cosmetically and construction-wise. No problems with sizing: it gauged (go/nogo) with no issues when installed. I expect it to shoot well.

Awesome experience as always!

by

These guys are simply the best! I have purchase quite a few items from them and always get a shipment confirmation from them usually within hours. That's service that is hard to come by these days. When looking for purchases I always check Primary Arms 1st! Other vendors should take note.

great deal!!

This bcg has all the specs you will find in ones costing much more. This is a fantastic value and you're not settling for a second rate part. All this plus Primary Arms incredible service made this impossible to pass up!
