Help my Auto mag classic is sick

[jzirkle1]

I have a 68 auto mag classic with 14 inch dye barrel. I have a bench mark expansion chamber installed also. The marker ran just fine with a 20 oz anti syphone tank. Very accrute and reliable. I decided to add a Centerflag hyper frame and the gun started to hiss and spitt and chop balls. I sent the gun and new grip back to centereflag. They said my rail was bent and that was causing the problem. I thought they fixed it but I gased it up shot it about 50 times. Worked fine. I went to a turneyment and never even got to shoot one game with it. SO I tore it back apart and put the old single trigger frame back on it and still have the same trouble. I am either going to fix it or sell the damn thing. I Hyper frame grip is new
I know if it isnt broke dont fix it. I should have listened

if the rail is bent......why not buy a new one?

I am not sure that the rail is bent.It worked fine before I put the other Grip on so why would the rail be bent. Doesnt make sence unless some one can give me an explaination.

Pt spacer

I have a hyper also on my mag and had similar problems, it most likely is the pt spacer, cuz thats what was wrong with mine. You probably need a shorter one.
