How to mount a rifle scope on a picatinny rail?

Once you get to know the significance and advantages of a Picatinny rail, now let us have a look at the process of mounting a spotting scope on the pic rail at home so that you do not need to call for help from outside.

  1. Open the rings of the Picatinny rail. Remove the upper sides of the rings so that you have only the lower sides.
  2. Now before you start the mounting process, make sure that you mark the ends of the upper and the lower sides. If you do not do it, you might get them mixed up once you are done with the mounting of your scope.
  3. For this, you can simply mark the ends with pieces of tape so that you know later which end goes where at the end.
  4. Now place the rings on the rail just loosely. Do not tighten them at this stage as you might have to adjust the alignment with respect to the scope. Just tighten them to an extent that they do not get off the rail.
  5. You can now place the scope over the rings and check if you have your eye relief just perfect.
  6. Adjust the position of the scope carefully according to the shape and structure of your scope to make sure that it rests on the rail in the right position.
  7. You can make adjustments to the power of your scope to the maximum.
  8. As regards the gap between the rings, you can have a better idea from the manual that comes with the rail because some of them require you to keep the rings closer to the turrets and some do not. So, this largely depends on the specific model of your Picatinny rail.
  9. Now with the help of a torque driver, you start tightening the screws on the rings.
  10. Adjust your torque driver depending upon the rail specifications.
  11. Make sure that the ridge of your ring fits in the rail towards the forward. It is important because when the rifle recoils, the scope thrusts towards the rear.
  12. Bear in mind that you have to position the rings with precision otherwise the alignment will be disturbed.
  13. Avoid having a play in the rings when you tighten them.
  14. You have to be careful when you buy a particular rail because the quality also plays an important role in how perfectly you set up the scope.
  15. Now is the time when you will put the upper sides of the rings right in place over the scope.
  16. Remember you marked the upper sides of the rings when you were dismantling? Now you have to get the right ends together.
  17. You might have to adjust the position of your scope backward or forward as the need may be in order to get the best eye-relief.
  18. Turn the power of your rifle scope to the maximum.
  19. Now set up the scope level by adjusting the vertical crosshair pointed straight down towards the center of the bore.
  20. At the same time keep the magnification of your scope to the minimum.
  21. As the last step, use your torque driver and screw the upper parts of the rings firmly, so that the scope is completely secured and does not move around.

Conclusion:

This concludes a complete guide to the types of mounts for your rifle scope and how you can mount the scope on a picatinny rail. You can now have a better idea of which mount is compatible with your rifle scope and which option you should go for. You can have your favorite mount from your nearest market.
