Your bolt carrier group is one of the most critical parts of your build. Don't buy an imitation. Spike's Tactical AR-15/M16 Nickel Boron Bolt Carrier Group. These complete bolt carrier groups come magnetic particle inspected and high pressure tested. The carrier is made from 8620 steel and the bolt from 9310 tool steel. The gas key is properly staked, the extractor spring has been upgraded with an O-ring for increased tension, and all surfaces are coated with nickel boron. Nickel boron is much easier to clean and can help your firearm run more reliably when heavily fouled or with little lubrication. 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.

Revised for - DID NOT CYCLE

by

Hello everyone recently I wrote a review for this bolt because I received a bad one and it would not cycle and broke pieces of my AR15. Today I write a review revitalizing that one and letting you all know that I got a good one it functions and works fantastically! The one I received was really clean and looked great I function tested it with snap caps prior to going to the range and all was well. Went to the range and fired 1 shot reloaded then 2 reloaded then 3 reloaded etc. Everything went through flawlessly as well as a rapid fire test. Took the bolt out after shooting and all was well cleaned it back up oiled it up and it was good as new. This bolt is a great buy assuming you get one that works going to give it 4 stars because it came pretty and this one worked only 4 not 5 because my first one did not function. Good Job Spikes Tactical!
