How To Zero A Rifle Scope

You just got a new rifle scope, fitted it and let me guess ... for some reason your shots are landing anywhere near the crosshairs?

There are sadly more sharp shooting rifle scope than just plonking the scope on the rifle and shoot forever after as an SAS sniper! You have to "put to zero."


Think about it. It's like a bike wheel. If you tighten the bolts wrong, too on one side for example, wrong turns and rubs the brake shoes. It is like a rifle scope. If it is not fixed properly is not online and even in air rifle, airsoft and paintball short ranges it will launch its accuracy right off. At longer ranges you will miss by a mile (well figuratively anyway!)

What "resets the midst of a reach?

The focus of a hearing or a scope means getting the reticle in position so that when you shoot. Zero point if you like. The point of impact. There is much discussion among shooters in the best way to zero a scope or sight. What I have written below is what I've been sending my buyers ebay range for the past year or so and I received many good comments back about it so I know it's OK!

How to zero a rifle scope

First you need to set a firm foundation scope mounts fitting well.

   1. Put the scope mounts on the rifle first with the upper brackets removed.
   2. Tighten in place using turns of 1 / 2 at the time so they feel solid and level as best as possible, ie, the downward pressure is as equal as possible. Do not tighten completely at this stage as you might want to slide up and down a bit.
   3. Now take the scope and set up open the rifle mounts.
          * Make sure the turrets of the backlash and lift are an up and right (these are the "towers" at the hearing. You use them later to make micro adjustments and adjustments for the wind field )
   4. Then put the top mount brackets and tighten - use partial turns again to reinforce.
          * Do not tighten completely at this stage, you may still need to adjust a little.

Zero range

   1. Lie on your normal shooting position and make sure you can see through the well of the scope ...
          * The distance between your eye and the posterior lens is called Eye Relief scope.
          * Unlike comic you do not use a scope by pressing your eye up against the lens of the scope!
   2. Once it is finished comfortable screw down all the fixtures so that their provision is sound --
          * Take care at this stage to maintain the partial closing laps and one by one to ensure the pressure is equal.

Now it's time to zero the scope for shooting:

   1. Load the rifle
   2. Take your standard apt / lie down shooting position.
          * Prone is the best way if you try to launch the placement positions of kneeling or more and you certainly is harder to make a "real test".
   3. Put some kind of white in the place say 20 yards - or whatever you think your "standard" range will be.
   4. "Using the cross hair of the white center - Take 2-3 shots - where they fell in relation to where you want them? Right, left, up, down - dead (lucky you!)
          * 2-3 shots are the best they will average out the inaccuracy of the shooter and give a feeling "more meaningful" to you how far or near zero is true.

Now it's time to use the turrets of the backlash and lift to get you dead set to zero on. These are the 2 turrets in the upper right of reach. See my website for pictures.

   1. The models vary, you probably screwed a cap off and expose any twisting the coin or a finger grained dial type.
   2. The top turret adjusts up and down. The left and right right one.
   3. If you have your instructions from the scope should have a table with figures to tell what each click adjustment in terms of moving the cross hair in the distance "x", eg, 1 / 8 inch at 100 meters.

The click of the single-lap use and take each time a new draft which now falls to calibrate the shot - basically fit dials up-down from the position of cross hair and left to right.

It's basically trial and error but with the test you get to where you need to be and to have confidence that your shot will go where it says! This may take some time and many shots. Be patient!
