36mm Scope Ring Mounts

The size 36 mm main tube is the second widest main tube diameter in use on modern rifle scopes. It is only used by Zeiss and Hensold for their massive, lowlight hunting rifle scopes and the last generation of Hensoldt tactical scopes. The rifle scope is mounted to the rifle with the help of two 36 mm mounting rings. When fastening the screws one must take absolute caution not to over tighten the screw. Doing so can result in marks and scratches on the rifle scope exterior or even worse in malfunctioned rifle scope due to structural compromises. The most force to be used when tightening the screw should not exceed 2.2 Nm.

The manufacturers who provide 36 mm mount rings are:

Even though it was an very unusual step for Zeiss to introduce scopes with tube diameter which no one else ever produced, producers of munts followed incredibly fast. 3 years after introduction of Zeiss Victory V8 scopes, there is more than 10 manufacturers of mounts that produce anything from mono-block mounts, individual rings, pivot mounts, custom mounting solutions.

36mm ring mounts have all possible forms, from very elegant hunting mounts with 15mm wide rings to tactical mono-block mounts with 30mm and more wide rings.

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, than 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 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 are becoming so popular in the 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 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

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.

Since 36mm mounts are mainly produced by premium mounts producers and are usually expensive, lapping is almost never needed. Due to this reason there is also almost no lapping tools available on the market for 36mm mounts. It is however a good idea to use a ribbon cut from latex/rubber gloves on the lower contact surface in the rings, when mounting 36mm scopes.

A Merkel Suhl Tilt-up mount is a mounting system found on Merkel repeating rifles KR1 and on their break barrel rifles like the single shot K3/K4 and at combination rifles B3/B4. This mounting solution offers great flexibility since the same mounts are used on such different types of rifles and on the other hand, it offers 100% repeatability. Other advantages are:

lightweight, small and elegant mounts,
low height of mounting, including for the scopes with rails,
very easy and straight forward handling of the mount.

This mounting system has 4 mounting grows directly on the barrel and a cross section for the recoil stopper at the top of the barrel. Mounting of riflescopes directly on the barrel offers an advantage that it is possible to change the barrel and the scope together. Merkel KR1 is a prime example where a user can have multiple barrels with multiple scopes for one rifle only. Additionally since Merkel Suhl Tilt-Up mounts offer 100% repeatability, the user can have multiple scopes on each of the barrels. This type of mounts offer true versatility.

Even though Merkel Tilt-up mounting system has 4 groves and one recoil slot, most of the mounts for red dot sights clamp only to two groves and not all four. Nevertheless these mounts also fit on all rifles with this mounting system and also provide 100% repeatability.

Merkel Suhl Tilt-Up mount is used on the following rifles:

Merkel KR1,
Merkel B3/B4,
Merkel K3/K4.
