Sean, I’m new here and looking to get information about the XCR in 6.5 Grendel. Have you been able to get your 6.5 Grendel XCR running reliably?
I do have experience running 6.5 Grendel in an AR15 and M16. They run 100% using Elander mags in semi and full auto. I’v had a few failures using the Unimags running 6.5 Grendel (which run 100% on full auto in 7.62x39). The 6.5 Grendel upper is setup with an Adams Arms piston system, so it may not represent how it would run with direct gas. I’d definitely try the Elanders if you’re still having issues.
Sorry....never saw this post. Just linked you to this thread regarding porting.
B/c of the shortage of ammo and too many car projects, I haven't been back out to test with the new ELander and warrantied ASC mags....or my Unimags.
It's on the list of things "to do"...just haven't gotten to it yet.
