I replaced the Leupold Mark 4 that came with the rifle with a NF 5.5-22X 56mm. I have the elevation dialed all the way down and the gun is still high at 100yds(3-4in) and even worse at 200yds (at least 6MOA hold under). I did not move anything when I changed up the scopes. Any suggestions? Am I missing something? I included two pics so you see how it is mounted.

| Looks like its your rings. Look at the gap below the two adjustment screws on the rear ring versus the front ring. Your scope is severly pointed down . Which would mean your barrel is pointed up in relation to your scope. You should be good at about 1200 yards!Cant comment on why it worked before. |

Good call Whitetainut. Unless he has some kind of device that is suppose to give him a 30 MOA rise for the purpose a long range shooting. I also would move the front rings closer to the front of the scope. With the rings close together and if that is a device to raise the rear of the scope up. Then with the rings close together it will be more than 30 MOA. So, all you did was remove the caps of the rings and dropped in the new scope? Maybe the old scope had more elevation adjustment than the new scope. Also did you lap in the scope rings? If not, I suspect you are really toqueing the front of the tube (in front of the elevation and windage adjustments). Please get back with us and let us know what you found. |

You have the adjustable Barrett rings. Don't reverse them, adjust them so they are both sitting on an even plane, then rezero your scope out. Barrett explained to me that the "rule of thumb" adjustment is to use a dime as a thickness gauge when adjusting the rings.

The hieght adjustable rings that are on the rifle look like they are adjusted too far up in the rear. Add back about 10-15 minutes of adjustment. Loosen the adjustable nuts on the side of each rig. Remove the bolt and buttplate from the rifle. Sandbag rifle and sight down the bore at something 100m away. Slowly lift the rear of the scope till you are pretty close on target. Tighten side bolts on the rings to about 45 in lbs. You're done. The adjustable rings are made for that reason. |
