I know this will be pretty petty to some, if so Please forgive me. I'm pretty anal when it comes to irreversable modifications to a new gun. I don't want to do something Ill regret later. I just bought a Gamo Coyote for hunting. I want to install some sling swivels on it. My dilemma is, do i put 1 or 2 on the front. I may want to use a bipod later, IDK. If I install 2 front studs what spacing do i use? Is there a standard or rule of thumb for the spacing?
