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.

Got this on the cyber Monday sale what can you say the price was great. The machining and finish on this thing is very impressive. I have two M4 clones and will use this for a back-up or for my next build.

Great product!

Great experience with Primary Arms. I bought this part along with many others to complete my first build and it all went together easily. I have about 300 rounds through the rifle already with no issues. Will definitely buy from them again.
