Ar shooting 4" left scope issue?

[savageboy23]

My ar is shooting 4" to the left and my side to side adjustment is all the way to the right. Is this a scope issue? I have a Stag Arms upper and a Ds Arms lower. A friend of mine said its because it's custom built and wasn't guaranteed. I personally think its a scope issue. It was shooting 8" left last weekend but I worked the side to side a little bit thinking that my cross hairs were stuck. Scope is a Nikon Monarch 5x20x44

Bore sight the thing and see where the muzzle is pointed in relation to your scope.......that'll clear things up right away.

What kind of mount or rings are you using?

I had a Nikon m-223 mount. Took it back and exchanged it for a Burris one...problem solved

Did you get the PEPR (or whatever ist called) one?

Yes bow shot that would be the one. I couldn't remember the name in my last post. When I purchased the M-223 mount the salesman never mentioned it would be a pain in my hind end to install correctly. Apparently they are windage adjustable when installed so your suppose to have a bore sight on the barrel?

Thanks for the suggestions everyone

That much off it is one of two issues (Probably) either the mounts are F'd U or its operator headspace......

It was the mounts. Changed them out and I was back on track
