Building a 6mm arc.

18in proof barrel. Looking at bolts (AR15). Is cmc gonna be ok? Recommendations out there?

Can’t find much. Looking for durability/reliability. Will probably be using a geiselle upper receiver if it matters.

JP is usually the defacto answer.  Pretty sure Proof recommends them for use with their ARC/Grendel barrels.  

I’m specifically talking about the bolt here, not necessarily the entire BCG.  I’ve only ever used JP bolts with regular phosphated FA carriers with my Proof barrels.  All have functioned flawlessly.

Some people use the Rexus bolt.

Or VSeven.

I can't remember the name of this place, but they have the JP in stock

This place has 1 JP in stock.

Maybe try here?

I just don't think you're trying hard enough.

Call Kelly Sanders of Sanders Armory in Florida. great products that he stands behind. www.sandersarmoryusa.com . I've used his bolts with no issue and also Odin Gunworks in the 6.5 G/ 6mm ARC and .22 ARC. Faxon in Ohio has good bolts.

65outfitters makes a pretty good 6.5Grendel bolt, that will work on 6mm ARC.

Recoil Off: RCA Ti BCG and Unrivaled Deadblow Comp Buffer Review


You’ll have to pair it with an AGB, but I’m using the RCA Ti BCG along with their bolt.
