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
