Thread: AR15 with a Proof Research 6.5 Grendel barrel

I got this Proof Research 6.5 Grendel barrel in from the States last week & had all the bits waiting to put the upper together.



I have a few uppers that go one the one lower & share the suppressor with a couple of rifles I have.



The proper carbon fibre barrel looks great, nice & light too



I took it up the range yesterday for the first time & tried it with some factory Hornady ammo.



I had also chucked some loads together with the 123 Amax & 8208 just under max load at magazine length to try



Looks pretty good to be fair, I hope the 300 Blackout barrel shoots as well

Interesting handguard. XLR Carbon?

No, but it does look a little like one to be fair, I can't recall the brand at the moment sorry.

Faar out it looks like a fantastic setup. 6.5 Grendel really seems to shoot like 6.5 6.5 Creedmoors little brother.

Nope its better/more accurate, but not as grunty

Is it just a matter of a barrel change over or is more involved to swap from a 223 cal to 6.5 grendel on a JP side charging AR?

What barrel length are you running there Greg?

I shot the Grendel I just built today using a case full of CFE. Damn consistent over the chrony, couple of loads had an ES of like 12fps

New bolt head as well and mags. 6.5 G is based on the 7.62x39 which has a larger case head.

Mine has a 24", haven't run it over the chronograph yet. Only just go my 20 MOA mount and need some weather to shoot!

Standard SAAMI chamber or one of the few variations Greg?

Standard off the shelf 6.5 Grendel 1-8 20" .875 Proof Research carbon barrel, a proper carbon fibre wrapped cut rifled barrel

These aren't a cheap barrel but come with barrel extension threaded muzzle etc ready to fit & shoot.

Had a play with some factory ammo I wanted the brass from in the weekend.



Pretty happy considering the time spent shooting the group
