You need a heavier mainspring. Should fix it

Go see Ed at Euless Guns

Also. POI will shift. Anyone that tells you that it doesn't really doesn't understand shooting precision rifles. It all has to do with harmonics. Long light barrels have the greatest POI change. Heavy short barrels are less likely to change. Putting a can on your rifle is similar to putting a brick on top of the muzzel. It changes the harmonics and will almost always shoot low from your previous non-suppressed zero. This is the basic but to really look at why, you have to look at all the variables (barrel length, barrel conture, ammo, length and weight of the can)

I have a trust just for the reason that if something happens to me it's not going to be as much of a PIA for my wife to deal with these items. Also, I'm in South Texas and noboby will give you a CLEO sig. As for cans, I run the AAC 7.62 SDN-6 on fighting rifles. For a precision rifle I would recommend Thunder Beast hands down. You are in Texas, give the guys at Silensor Shop a call. Dave, owner, takes his time to educate is customers. Plus they have the best prices in Texas. I have bought 6 cans from them over the years. Very happy and easy to deal with.
