It's worth the money for the flat side carrier. - TRYBE Defense Milspec Complete 6.5 Grendel Bolt Carrier Group (BCG) (Type 2 Bolt Face)

The bolt that came with this carrier is out of spec and will lead to jams. One of the lugs on the bolt was not lining up with the lugs on my barrel and started to cause jams, double feeds, and improper ejections. I how ever did match it with the JP Bolt and It performs like a Amazingly now. I would still recommend this carrier for the price but throw away the bolt. The bolt is a peace of junk and get yourself a JP bolt to replace it. I hope this helps anyone looking for this as a cheap addition to their budget build. I took away two stars for the junky bolt. If it was just the carrier it would get a five star rating.
