The sticking live jam was bad news. A rifle that breaks in half every time you cock must be repeatable coming back into battery, crucial when the sights are not on the barrel.Got to wonder how much your new scope might have had to do with the accuracy you found. Did you try out the fixes and bipod with the old scope?
I would not recommend installing a bipod on an np with it's famous (kicks like a mule) recoil !!See post below :http://www.network54.com/Forum/79537/message/1370910438/Anybody+figure+out+a+way+to+mount+a+bipod+on+a+Benjamin+Trail+NP+XL+1100-+nt
