I have a slightly older silencer that I bought for a specific build. That guild did not happen so now I am trying to it for general purpose.
It is a .22 can with a steel tube and aluminum mono core baffle that unscrews from the front.
I tried to use it with my dedicated .22 AR CMMG upper (.22lr barrel) and I got baffle strikes. I tried it with another can and 2 different types of ammo with the same results. Bullet impacts were very random. Looking down the barrel from the chamber you could just barely see one side of the silencer. I sent that upper back and they did find an issue and sent me a new upper.
We are visiting family this week and I brought the new upper to try out. I sighted the rifle in and making ~1.5" groups at 50 yards with bulk plinking ammo. I put the can on the gun and my POI shifted just over 1' left and my group opened up to about 8". I removed the baffle stack, but left the tube (heavy part) on the gun. POI and grouping returned.
Now I am suspecting baffle strikes again. Looking down the barrel you could see the baffles and appeared to be even all around. We took the baffle stack out and opened the bore to .28" on a lathe. Now you can not see any of the baffles looking down the barrel. Test fired it again at a pop can at ~20' and still shooting ~1' left, no idea about grouping. There are no obvious spots where the bullet is touching the baffles.
Well now I am baffled. Since I am not home I do not have another can with me to test, no other ammo and no other rifle to test the can on. I am going to try and make time this weekend to do those test, but I another project that is more of a priority.
Any thoughts of why this might be happening or other things to check? I have several cans and thousands of rounds down range with them, this is my first issue..
