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 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.

good for carbine , needs tweak for pistol

by

comes with standard extractor spring (4 coil) and standard o-ring. that would work fine in a carbine or rifle, but for pistol with short barrel (7.5") i was getting failure to extract, so i had to upgrade the extractor spring to a 5 coil spring to fix the issue.
