How to Choose Mounts For Your Rifle Scope and Rifle

The excellent news is that except your rifle is an uncommon or classic kind then choosing the proper scope mounts is straightforward. On this article you may study how you can shortly decide what kind you want.

So the, you’ve got a brand new rifle and need to get a pleasant telescopic rifle scope that can assist you shoot higher? And make it look very cool too 🙂

Choosing a rifle scope generally is a difficult course of in itself and I will not cowl it on this article besides briefly now: If you might be capturing in regular daybreak to nightfall kind gentle at ranges not more than say 300 yards/metres then get a Three-9×40 or related variable magnification scope. Three-9 = it ranges between Three and 9x magnification and the 40 bit means it has a 40mm vast lens on the finish. It is a superb basic function mixture and there are choices for many budgets from low cost to army.

Now what you want to be able to repair the scope to the rifle are mounts. This shouldn’t be difficult however to avoid wasting time, trouble and value in returning incorrect mounts to the vendor it is good to get it proper first time.

There are 2 issues it’s good to know:

1) What mounts are want on your scope by way of (a) peak and (b) ring diameter.

2) What kind of rifles scope receiver grooves you’ve got.

In lots of circumstances it’s possible you’ll discover scope and mount packages offered collectively, in these circumstances you possibly can make certain that they are going to be right for the scope however you continue to have to make certain that they are going to be OK on your rifle earlier than you go forward. If not then you definately’ll have to ask the vendor if they will swap for an additional kind.

What mounts are want on your scope

Scope mounts are available Three predominant heights. By peak I imply how excessive they may elevate the scope off the rifle. There are Three predominant heights:


  • Low – For scopes with upto 32mm lenses
  • Medium – For scopes with upto 42mm lenses
  • Excessive – For scopes with 40-56mm lenses


There are additionally things like extremely excessive however you are unlikely to wish these except you’ve got a specialised requirement.

The dimensions of lens rule is an efficient basic information but in addition carry your rifle into consideration. If it has say a bolt motion then it is best to go for a excessive mount even with a smaller lens scope.

Scope Tube Diameter is the second consideration when matching mounts to scope.

Most scopes have a 25mm (1 inch) physique tube and you will find that almost all mounts are for these scopes. If not then they may specify that they’re for a distinct diameter physique – you may discover some with 30mm tubes. So ensure what your scopes physique tube diameter is the select your mounts to match.

What kind of rifles scope receiver grooves you’ve got

By this I imply the place the place the scope mounts will connect on high of the rifle.

Generally known as the scope base or rail, grooves or receiver.

There are 2 predominant varieties: Commonplace and Weaver (additionally typically referred to as Picatinny or Tactical)

In flip mounts are generally known as Commonplace or Weaver mounts.

Commonplace –


  • 2 grooved traces working entrance to again alongside the highest of the rifle physique
  •  Between 9 and 13mm aside.

Weaver/Picatinny/Tactical – 


  • The grooves are 20-22mm aside
  • The bottom is usually extra of a stable block design with horizontal “slats” throughout it (some mounts have arrestor blocks of their bases that give an additional diploma of lock by mating with these grooves)


Commonplace bases are because the title suggests quite common. They’re the normal as of late for air rifle and paintball weapons and lots of decrease powered pistols.

Weaver bases are to be discovered on increased energy increased recoil rifles, particularly army, searching and shotguns. They’re additionally discovered on many airsoft bulk small pistol primers rifles the place the replication could be very correct.

Your mount selection components mix then…Examples

Your have an air rifle with a normal base and are getting a Three-9×40 scope with a 25mm tube = Commonplace Medium or Excessive mounts.

Looking rifle with 20mm weaver base  and also you’re getting a 6-24×50 scope with 30mm tube = Excessive 30mm Weaver mounts.

1 or 2 piece?

It is a additional division, I add this for completeness. In the event you’re new then I would say go for two piece as your first kind.

1 piece is the place the entire mount physique is a single molded unit. This sort could be very robust and stable however might not be an possibility when you’ve got a bolt motion or high journal rifle.

2 piece – Merely 2 mounts that you simply place on the rifle base rail. Not fairly the rigidity of the 1 piece however extra versatile by way of positioning and skill to “work round” obstructions. Cheaper too.
