Bear Creek Arsenal 6.5 Grendel Type II Bolt Carrier Group
The Bear Creek Arsenal 6.5 Grendel Type II Bolt Carrier Group has been magnetic particle inspected for quality assurance against defects. Perfect for your next 6.5 Grendel build.
Safety Note: Choosing 6.5 Grendel comes with an added complication. There are “Type I” and “Type II” bolt/barrel specifications out there, and you CAN NOT mix and match parts for each of them without risk of damage and/or injury. Type II is by far the most popular configuration, but pay attention to what you are buying! A Type I bolt won’t chamber rounds in a Type II barrel at all. Even worse, a Type II bolt mated to a Type I barrel will create excessive headspace and result in a rifle that is dangerous to fire.

I bought 3 of these. None of them will extract a spent round. When I put a different BCG in my gun it works just fine. I tried putting a different extractor spring on but still does not work, I guess thats what I get for trying too save a few bucks.
Check the staking!!

Everything was well done except the staking, which was barely visible. One of the two bolts loosened without any resistance at all. Fortunately I found this while doing the initial disassembling and cleaning of the BCG.
<br>Best to check this carefully before using for the first time.
