It is a very recurring question in our day-to-day operations. Which mount is best for my rifle and scope combination?
With this simple explanation from Sportsmatch UK, we are going to clear up many doubts, and we hope you find it very useful.
We base this on the basic concepts of rail width, scope tube diameter, and mount height.
In this case, we will illustrate it with examples from one of our favorite brands for this purpose.
Which carbine or rifle mount do I need?
Whenever possible, a one-piece mount is recommended. Certain carbine models, including many bolt-action riflesdo not readily allow the use of this mount. Two-piece SportsMachs can be used for these rifles. They are extremely robust and reliable and like all SportsMach BSM products are guaranteed for life.
Rail Width
About 95 % of air rifles and rimfire rifles (.22 cal.) have 9.5-11-5 mm rail widths.
BSM SportsMach offers a wide range including fully adjustable versions that even feature lateral adjustment for rail centring.
They also offer wider dovetailed rings such as the 13mm series to suit the latest BSA carbines.
There are versions that fit Tikka rifles and CZ527 rifles, as well as the 17mm version that fits cz550 rifles. Some confusion may occur as some rifle and carbine manufacturers state the width of the dovetail at the widest point, but BSM measures at the narrowest point.
Tube diameter
The most common size is 1"" inch ( 25.4 mm) but of course 30 mm Visor versions are very common. Before the choice of the mount we will always take into account the characteristics of the scope. Very important is the diameter of the tube and the outer diameter of the lens of the rifle scope. These two parameters are essential for the correct choice of the mount.
Mounting height
As you will see we declare a "dimension up to lens diameter". Due to rifle carbine and scope scope designs varying enormously, this can only be used as a guide.
If you are unsure of what height is appropriate we suggest checking using the following diagram. The A dimension is shown next to each product in the product images below.
The way we establish that the lens space is sufficient is deduced from half the outer diameter of the lens and half the diameter of the viewfinder tube and the result is the minimum height we require.
- Following this simple table you will be able to choose your mount.
