Thanks corps! I'll definitely look into switching the inner barrel (even to my stock TM one if needed)
Anyways, a little update. yesterday, i went to HSP - excited to field my new setup (even with the decrease in FPS).
However, I was extremely disappointed with the results. I was getting random fliers that veered drastically to the right ever 5th or 7th shot on semi. On automatic it wasn't any better as the shots veered in every direction.
Corps, was your friend having problems with the above other than just a decrease in FPS?
