General features

There is more than one way to mount a rifle scope, but the most widespread is the option with rings. It has numerous advantages, for starters, it's affordable and available in the biggest number of versions. A lot of today's riflescopes need a 30mm scope mount - because they feature a 30mm 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 tubes are the most common one in today’s world, the range of 30mm mounts is the widest among all mounting options. 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 mounts are however in most cases much wider (up to 32mm) and thus more robust and bigger. With very wide rings the pressure on the scope tube is better to 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 riflescope 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.

Is lapping of the rings really needed?

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.

When the ring is constructed from two near half circles - so if the circle of the ring is split in half, roughly in the ratio 50:50 and such rings are mounted on two separate mounting bases, then lapping is recommended. If lapping is not performed, the very small offsetting can be present when all the different pieces of the mount come together and when both rings are mounted on two separated bases. If the mounting of two high-quality rings is done on a single-piece base, then lapping is not needed. This is one of the reasons that Picatinny rails style are becoming so popular in recent years.

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 occur due to this reason are 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 of the top of the ring then lapping is not required as the design is plastic enough to bend slightly and adjust its shape to the scope tube. The same applies to ½-1/2 rings mounted on the single-piece base.

It may be a good idea to take into 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 monoblock mounts and all mounts are 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.

Suhl Claw mounts were the most common form of detachable/repeatable mounts on European rifles before the modern pivot mounts emerged on the market. This type of mounts were mainly used in central Europe and especially dominated in Germany and Austria. Hence, for this reason such mounts are called German Claw mounts in the English speaking lands, whereas in central Europe the same mounts are usually just referred to as Suhl mounts. Suhl mounts are compromised from the front ring which embraces the objective bell and the rear ring that is located on the central tube of the scope. The prime reason for such popularity was the extraordinary repeatability and reliability, which is still remarkable by today’s standards. There are however some drawbacks with this type of mounting solution and due to this reasons their popularity rapidly declined in the last 2 decades. These are:

  • High price (Suhl Claw mount is the most expensive mount among all and a price of 1000 EUR or more for a single mount is quite ordinary. All such mounts are custom made by gunsmiths and their installation involves by far the most work input among all mounts.),
  • Front mounting base often has to be installed on the barrel (Almost all modern rifle scopes with 50 or 56mm objective lens and eye-relief of 80mm or more need the front ring around the objective bell, which means that the front base of the mount is placed on the barrel. This interferes with the free floating barrels and reduces accuracy.),
  • Sample to sample variation (The quality of the German Claw mount depends on the skill and knowledge of the gunsmith that installed it or even made it from scratch. That means that there are very big differences in quality from mount to mount.).
