Hey everyone,
I recently got my Sandman S and am using it on a couple of different rifles using their keymount brake on both rifles. On my 224 Grendel (AR15 platform) the POI shift with suppressor is what I would say is very normal, a .3 mil shift. But on my AR10 (.308), the shift is 8 mils right and 3 mils up. With that much change I figured there must be something else going on, like maybe scope or scope mount...but the optics are all good.
Anyhow, I put the Area 419 brake back on which I've had on the rifle since I built it, rezeroed, and the rifle shot as expected. Then I put the keymount brake on again, rezeroed, and the rifle shot as expected. But as soon as I put on the Sandman, the POI shift is huge and it's not consistent either. It's not like it prints 1/2 MOA groups at 8 mils right and 3 mils up. It won't shoot even a 3 MOA group. No evidence of a baffle strike. Everything looks normal.
The AR10 has a Lothar Walther KA profile 20" barrel and it's been a consistent 1/2 MOA shooter ever since I assembled the rifle. Could I have a bad keymount brake?
Thanks in advance for your help.
