EAA is selling Rifle Barrel Inserts for the IZH43, IZH43K, IZH43KH, or MP213 shotguns. Has anyone try them? The Calibers are 45-70, .308 WIN, .222, .223.
If they have adjustments like the high end double gun ones for using sub calibers they should work okay. If not then it will be a crap shoot on where the POA is. I would also be interested if anyone has tried them.
I have used the shorter ones that MCA makes and they were okay for plinking but I wouldn't trust them for hunting.
