I don't shoot long range but that does'nt mean I haven't toyed around with the guns

;D
One of the biggest problems with the Sav F-Class stock is the height of the forearm not so much the bags fault.
Raising the center of gravity that high allows all sorts of torque to wreak havoc on the gun and bag setup.
This is the only stock I know that addresses that issue fully and is inlet for the Sav action.

I found one used on this sight and it really tamed the gun. No more bucking around.
If your interested try to find a used one.
Reportedly trying to buy a new one can lead to very long wait times and frustration. Just what I've seen on the web, maybe things have improved.
Is the bag gripping the gun tightly legal in F-Class?
