Begadi PRO 70° "MAG7" AEG R-Hop Bucking / Rubber (Air Sealed, for approx. 7mm barrel window) -black-
Other interesting articles:
The MAG series are newly developed R-Hop Buckings/Rubbers from Begadi, designed in Germany!
These are specially designed for modern AEG/S-AEG weapons and HopUp units and have some special features to increase the range and reduce the dispersion:
Patch:
Our patch of the MAG5 and MAG7 bucking has a radius of 2.9mm (5.8mm diameter). This is therefore slightly less than the BB itself and thus ensures accurate centering of the BB in the barrel. Likewise, the BB is guided straight during firing to prevent runaways to the side. This patch is an R-hop and is particularly suitable for heavy BBs.
Alignment:
To prevent the bucking from twisting on the barrel,
the patch lies on the left and right directly on the barrel window.
Seal & Comparison:
This is where the difference in the available HopUp rubbers lies. Especially with HPA systems, it often happens that the installed Nozzle cannot be changed and is therefore not compatible with every rubber. This is where our SHP and MHP series comes into play.
Our existing FLY and MAG rubbers have a slightly larger seal, making them compatible with flat nozzles. (e.g. Begadi PRO Nozzle with double O-ring).
However, some manufacturers use a pointed Nozzle in their guns, if this is the case, the Nozzle had to be changed or adjusted in length. In the SHP and MHP series, the seal was made smaller, so now pointed nozzles no longer need to be changed.
Notice: For a flat or round Nozzle we still recommend the FLY or MAG series, for pointed Nozzles the SHP or MHP series should be used.
Durability and Wear:
All of our Begadi PRO Buckings are made from a very tough and durable rubber compound. This keeps the set HopUp effect constant over a long time and wears out much slower than conventional rubbers.
You also don't have to worry about the rubber cracking on the patch during disassembly or maintenance. However, you should exercise some caution when pulling it off. Please note the correct choice of hardness for your weapon (energy and bullet weight). If a too soft rubber is selected here, the wear increases!
Marking/Hardness:
To be able to distinguish our buckings, the respective version is directly marked. The rubber compound (hardness) is reflected in the color: 50° green - 60° blue - 70° black.
Thus, it is immediately apparent which version it is.
Versions 5mm or 7mm:
Another special feature are the two available lengths of the inner patch. The respective number indicates the required length of the barrel window.
- 5mm version: These Buckings are compatible with all standard barrels with a HopUp window of 4.8 - 5.2mm. For particularly heavy BBs (0.40g+) we recommend rather to reach for the 7mm version + tuning barrel, since here less pressure of the Tensioner is needed
- 7mm version: This is a special version which is only suitable for tuning barrels with a 6.8 - 7mm window. (DaVinci 70, TNT...). Due to the significantly longer patch, a much stronger Magnus effect is created here and is especially suitable for heavy BBs very well. Please note that it can come with light BBs rather to an overhop! We recommend using the 7mm combination only from 0.40g+ BBs.
Tensioner:
We have also developed matching tensioners for our Buckings, these are exactly matched. If our tensioners are not compatible with your HopUp unit, please use Flat Hop tensioners.
Recommendation:
- Begadi PRO 70° HopUp Tensioner (D=3mm) -5mm- for barrels with standard (approx. 5mm) barrel window
- Begadi PRO 70° HopUp Tensioner (D=3mm) -6mm- for barrels with large (approx. 7mm) barrel window
- Begadi PRO 70° HopUp Tensioner (D=2,5mm) -5mm- for barrels with standard (approx. 5mm) barrel window
- Begadi PRO 70° HopUp Tensioner (D=2,5mm) -6mm- for barrels with large (approx. 7mm) barrel window
Shooting in:
Like all other available buckings on the market, ours must be shot in. A constant HopUp effect is achieved after approx. 200 - 400 shots. (Depending on energy and bullet weight)
Avoid setting too much hop with the first 2 magazines, as the patch must first work its way in.
MAG/MHP or FLY/SHP version:
Our FLY and SHP is more like a flat hop, offering very good centering and a low spread circle with good range. In comparison, our MAG and MHP is an R-Hop bucking and produces a stronger HopUp effect. The range of the MAG and MHP version is thus slightly higher, but the spread circle can be somewhat larger here, accordingly, the MAG and MHP should only be used with heavy BBs.
Special case Begadi Sport M14 / Cyma M14:
The M14 from Cyma uses a significantly shorter bucking. Our normal FLY5, FLY7, MAG5, MAG7 can be used here, but the rubber must be cut off at the front (towards the muzzle) by 2 - 3mm. If you do not want to do this yourself, we already offer a ready-cut version here. - Art. 26021016

Compatibility:
In the following table we would like to give you a short exemplary overview for which HopUp Unit we recommend which Bucking. Please note that there may be differences depending on the manufacturer and weapon!
In most cases, only the nozzle length must be adjusted here. Unfortunately, we cannot cover all weapons on the market, since the barrel used, the tappet plate, the sector gear and the shell also have an influence on the required nozzle length.
The buckings marked with green are compatible with the original nozzle length, marked with white means that the nozzle length must be adapted (changed).
