I have a Smith and wesson m&p 15-22 with a leupold vx2 3-9 rimfire scope mounted on a burris p.e.p.r mount. My elevation and windage knobs maxed out and I'm still about 3in off both ways. This happened to me originally with a cheap bushnell scope and I thought maybe the problem was the scope. I got this leupold scope and I have the same problem. I unmounted the mount and backed it up on the rail to test it out and same issue. Is it possible this mount is too high for my 22lr? Still wouldn't explain the windage issue though. Maybe the mount is a lemon? I had also sent the gun in for warranty work for malfunctions and they did replace my barrel along with a couple other things. Could it be when they replaced the barrel they didn't align it properly? I could use some serious help figuring this out. I have the same mount for my 223 and had zero issues zeroing it. Any ideas??
