This is a Griffin Armament Bushwhacker 36 using their AK taper mount mounts to the barrel's face well before it his the gas block. Since its a 36 caliber suppressor I have some built in wiggle room, but I'd rather be safe than sorry.
When I first installed everything the alignment rod cleared but clearly was off center towards the 4 o clock position. Reading some advice here, I gave the barrel face and threads a good cleaning as this was a used AK.
It's definitely improved, but should I look at something like a sharpening stone?
Pics 1 & 2 are after cleaning, 3 is the first check and 4 is the muzzle device from the side.
