The purpose of fixing the Weaver bar is to create a guide of this type on smoothbore guns having a ventilated bar, the width of which does not exceed 8 mm.
Device Description
The design of this device is quite compact, and also very light. In addition, it allows you to "squeeze" it into the ventilated strip. This is a very important point, since it remains possible to view through an open sight. Another rather important point that arises when installing the Weaver bar is that the collimator sight will also be mounted very low. Here it is necessary to pay attention to the following fact. This model is designed to install a sight, the weight of which does not exceed 400 grams. It is not recommended to mount heavier devices, because of their weight, the bar is likely to break when fired.
Bracket bracket device
The transition bracket, which is used to attach the collimator sight, consists of two parts that are inserted into the internal rectangular grooves of the vented bar. They are inserted on the left and on the right side, after which they are pulled together by four screws of type M2. The brackets of the Weaver strap are firmly pressed against the side surfaces. This design and installation method allows you to aim with a mechanical sight or front sight, without removing the device itself. However, this is only possible if no additional weapon sight is installed.
In order to avoid the displacement of the Viver’s bar, which occur during firing due to recoil of the weapon, there are special rectangular type towers in the lower part of the structure. There are also several holes for additional bolts of type M3. Using these fasteners, you can finally fix the brackets after installing all the necessary parts.
Features and characteristics of the device
The main purpose of this design is to mount collimator sights on the vented bar of smooth-bore weapons. The width of this strap can be in the range of 7-8 mm. The height of the ventilation hole for a successful installation should not exceed 1.5 mm, and its width - not less than 23 mm. The main material for the manufacture of brackets is steel.
If we talk about the characteristics of this device, then they are as follows:
- the length of the Weaver strap is 110 mm;
- weight of a small design within 70 grams;
- device dimensions 110x21x9 mm;
- steel 45 is used as the main material;
- chemical oxidation or black burnishing is used to cover this item.
AK device
The cover of the receiver with the Weaver strap on the AK / AKM is used to install not only collimator sights, but also optical. It uses modernized models that allow you to not remove the native mechanical sights. The biggest advantage and difference from the Chinese counterparts of this device is that it does not play, and also does not shift with a large shot.
Additional positive qualities include ergonomics, low weight, and strength. The total weight of the device is only 120 grams, while the standard model has a weight of 80 grams. It is worth agreeing that the difference of 40 grams is not significant. In addition, the installation of such a bar solves the most important task and at the same time eliminates the biggest problem of carbines made on the basis of AK - this is placing the sight at a comfortable distance from the eye.
These covers are entirely milled from solid billets of an aircraft aluminum alloy model D16T. The use of this material provides high strength, accuracy and low weight. Here it is worth highlighting that the installation of this device will not interfere with the cleaning of weapons. One of the pretty nice features is the so-called zero return. In other words, after removal and reinstallation, no second sighting is required.
Weaver tail plank
Here it is worth saying right away that this bar itself is an improved version of the dovetail. The difference between them lies in the design, which is more complex in Weaver. In addition to the fact that this type of bar can be screwed along the entire length of the sight, it also has an additional stop, which can be used as a basis for adjusting the unsteadiness. In this case, the mounting of the optical sight will be as reliable as possible.
By itself, this bar is considered quite complex in design, but at the same time its installation is very simple. In addition to attaching optics and a collimator, you can also install a laser pointer or tactical flashlight. Another distinctive feature was the fact that it is possible to install not only on rifles, but also on pistols or even on sports crossbows. In addition, it becomes possible to quickly change the optical device, which plays a rather important role during hunting.
