Best AR-15 Bolt

BCM I believe makes the best bolts and having an extra is a good idea.

Quality product and I wouldn’t hesitate to buy again. PA was prompt with shipping, but FedEx took a couple extra days.
It’s BCM, what’s to be said

Let me start by saying that Primary Arms did a great job promptly shipping out my order, but the problem came dealing with Fed Ex. I ordered on Monday, P.A shipped on Wednesday and it took until the following Tuesday for Fed Ex to deliver. They first said package would be delivered Saturday, then Sunday, the an exception was issued, then it was finally delivered on Tuesday. Not very good considering the cost of shipping IMO.
Great!

Cratering on CCI 400 primers
by Mark -
I'm loading 75 gr heads with 24 gr of TAC. A very common load. The CCI 400 primers were cratering. This didn't happen with other primers like #41. This was happening with my 3 AR bolts. Things being what they are I couldn't walk away from thousands of small rifle primers. Two of my bolts are Rock River and the third was also a name brand. I looked into having a bushing installed on the bolts but again the way things are I didn't want to send my bolts out to have that done and I couldn't find over sized firing pins. For 556 ARs its recommended that the primers should have a wall thickness of .025. CCI 400 are .020. Bottom line is these bolts run the CCI primers with no cratering.
