AR15 Upper Receiver Action Block

[Andy]

Does anyone in the Portland area sell the upper receiver blocks?

I'd like the change out my muzzle brake and would probably end up spending the same amount to have someone else do it.

Thanks,
Andy

To change all the muzzle brakes on my AR Barrels I made my own barrel clamp. Two pieces of red oak clamped together and drilled right down the part line with the first drill size under the barrel diameter. Clamped it in my vise and got the job done. My biggest issue was with the "Armorers Tool". For some reason they make them too thick to fit between the crush washer and the shoulder of the "brake" or flash supressor. Have had to grind every one I've had to fit.
