Range Report/Gemtech Mock Silencer

[NUTTBALL763]

Well I finally got to shoot my 15-22 today which I bought back in January. I put about 300 rounds through it and only had one shell get caught up. I was using Federal Ammo 36 grain. I also had placed a Gemtech Outback Mock Silencer on it since I have the threaded barrel. Now with this thing on my rounds were about 2 or more inches off my zero. However when I removed it, I was keeping a group at 50 yards within a half dollar. I had several others try it with the same effect. Has anyone else experienced this with the Gemtech?

If you groups r just moving that is normal anytime you have a mass on the barrel it will change the zero slightly... but if you r shooting larger groups its design flaw in the suppressor the whole is to small... but point of impact change is normal..

Sounds like POI change from barrel spring which is normal when you add mass to then end of a hollow tube it's going to bow, no matter how rigid it is. You have to figure, even if it's a very small amount of bow, it's still going to change POI.
