I had that problem . My POI was always to the right , iron , red-dot , scope all rifles . My problem was canting the rifle .I was shooting about 3/4 MOA to the right . I would shoot sub MOA groups but always to the right . Every time I pick up any rifle and put it up to my cheek the cross hairs look canted . My natural/comfortable stance/hold makes the rifle cant . I re leveled all my scopes and have been really making an effort not to cant my rifle . I'm shooting better now .
Why do I carry a 45 ? because they don't make a 46
