Hey guys, Ive been lurking around for almost a year but just now decided to set up an account. Recently I purchased a S&W M&P 15 along with a 3-9x40 Weaver scope. Since I have installed the scope, I have had hell getting the gun sighted in. At 40yds, I couldnt hit the paper at first. Today I finally had it hit center but with the next shot, it would hit as high as 3-4in. The scope(or rifle for all I know) is wanting to shoot high and right and I have tweaked the adjustments so much that Im in a world of pissed off. So with all you can gather from that, would you say is the issue? Gun, scope or shooter? Other than continuing to be patient with it, Im at a loss. I appreciate any help I get.
