The most common mistake new players make when looking to improve their accuracy is to buy an airsoft scope but not take the time to set it up properly. An incorrectly mounted or zeroed scope will do nothing to improve accuracy, and could make your shooting even worse.

In this article, we’re going to be explaining how to properly mount your new scope to your rifle as well as showing you how to zero your scope for optimum accuracy in the field.

Mounting Your Airsoft Scope

Where on the gun you mount, your scope will depend on the scope’s eye relief and the length of your stalk. Approximately 3 - 4 inches should be about right, but this will vary from scope to scope.

Once you’ve decided where you want to mount your scope, take the scope rings and mount the bottom section that fits to the rail on the gun where you want the scope to sit. Tighten the bolts by hand and then set the scope onto the rings.

Lift the gun and look down the scope. You want to find the spot where, when you lean against the gun, you have the perfect eye relief. This will be the distance between your eye and the scope.

Once you’ve found the right spot, try to get the scope rings as far apart from one another as possible. This will ensure maximum stability for your scope.

Close the scope rings by fitting the second half of the rings on top of the scope, sealing it in place. Fit the screws into the top of the scope rings and tighten them enough that the scope can still twist in place.

Look down your scope and make sure the line on the cross is perfectly in line with your rifle. If it’s not, then this will greatly affect your accuracy. Twist the scope until you have it perfectly inline. Once it is, tighten your scope rings fully.

How to Zero Your Airsoft Scope

Once your scope is properly mounted, it’s time to zero it. Before you do this, make sure that the hop up is adjusted so your BB trajectory is as much a straight line as possible. Then, familiarise yourself with the different knobs and dials on your scope, in particular:

  • Windage - This will move your reticle to the left or right.
  • Elevation - This will move your reticle up or down.

The aim of zeroing your rifle scope is to adjust the windage and elevation on your scope to ensure that your point of aim matches your point of impact.

Start firing from 5 yards. When you're satisfied that this is zeroed, move back to the distance you’re likely to be shooting at. It can help to have a friend spot you to see where on the target your gun is hitting.

Continue adjusting and firing until your point of aim and point of impact are perfectly lined up and then, Voila! Your scope is zeroed.
