There is more than one way to mount a rifle scope, but the most wide spread is the option with rings. It has numerous advantages, for starters its affordable and available in the biggest number of versions. A lot of todays rifle scopes have a 30 mm main tube diameter. This means that in order for you to connect your rifle scope to the firearm you need the 30 mm rings for mounting. The most important thing when mounting a rifle scope with rings is to be aware of the appropriate force needed to fasten the rings. Go over the limit and the structural integrity of the rifle scope will be compromised. Rings can also leave a visible mark if not tighten accordingly. The amount of torque should not exceed 2.2 Nm.
Since the rifle scopes with 30mm tube are the most common one is today’s world, the range of 30mm mounts is the widest among all mounting solutions. Even on our webpage, this category of mounts is the biggest. There is almost no firearm in existence that would not have at least some sort of mounts for 30mm scopes.
Rings for the 30mm scope tubes on hunting rifles are usually 15mm wide and thus slick and elegant. Tactical mount are however in most cases much wider (up to 32mm) and thus more robust and bigger. With very wide rings the pressure on scope tube is better disperse and a better and more secure fit is achieved. Wide tactical rings also leave fewer marks on the scope tube. On the other hand bulky tactical rings don’t really look appropriate on elegant hunting rifles.
While many mounts meant for hunting rifles are still made from steel, almost all tactical mounts are made from aluminum. High quality European mount producers use high quality aluminum alloys which are equally strong as steel but much light at the same time.
Hunting mounts with 30mm rings usually have 1/3 – 2/3 arrangement of the rings and tactical mounts usually have ½ - ½ arrangement.
The 30 mm rings are available from: MAK, Kozap, EAW, INNOmount, Recknagel, Rusan, Dentler, Henneberger, Contessa, Leupold, Vortex, Sako, Hawke and Madritsch
Lapping is a process that is essentially lining two mounting rings perfectly to one-a-another. It is done with special cylinders that grind off the excess metal.
In the worst case scenario the axis that runs through the center of the rear ring does not completely match the axis that runs through the center of the front ring. For this reason the scope, if mounted into such rings is under unwanted structural stress. The most obvious problems that occurs due to this reason is less than perfect optical performance, tracking problems, the side focus mechanism can stop working and the point of impact groups can be dispersed.
If the ring is designed in the fashion of 1/3 base of the ring and 2/3 the top of the ring than lapping is not required as the design is plastic enough to bend slightly and adjust its shape to the scope tube. The same applies for ½-1/2 rings mounted on single piece base.
It may be a good idea to take in consideration to choose the 1/3 : 2/3 rings as they do not require additional lapping to be fitted properly. Or use a single piece mounting base.
Lapping is also not required with mono block mounts and all mounts made from one piece of material and alignment of both rings is usually perfect. It is also not required with high quality European mounts, since their tolerances are minimal.
