Begadi PRO 50° "VSR5" R-Hop Bucking / Rubber (Air Sealed, for approx. 5mm barrel window) -green-
The VSR series are newly developed R-Hop Buckings/Rubbers from Begadi, designed in Germany!
These are specially designed for modern spring pressure weapons and HopUp Units and have some special features to increase the range and reduce the dispersion:
Patch:
Our patch of the VSR5 and VSR7 bucking has a radius of 2.9mm (5.8mm diameter). This is therefore slightly smaller 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 runaway to the side. This patch is an R-hop and is particularly well suited for heavy BBs.
Alignment:
To prevent the bucking from twisting on the barrel, the patch rests directly on the barrel window on the left and right sides.
Seal:
Our VSR Buckings feature a 5.95mm diameter at the rear, this provides a very good seal to common cylinder heads (nozzles). For classic VSR systems we recommend to use cylinderheads which have no steps at the nozzle. (See last picture below)
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 for 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 too soft a rubber is chosen here, wear will increase!
Marking/Hardness:
To be able to distinguish our buckings, the respective version is directly marked. The rubber compound (hardness) is reflected in the color: 60° blue - 70° black. Thus, it is immediately apparent which version it is.
Versions 5mm or 7mm (running window):
Another special feature are the two available lengths of the inner patch. The respective number indicates the required length of the barrel window, standard = VSR5, for barrels with a large window the VSR7 can also be used.
Our Buckings are compatible to all VSR and Hybrid barrels with and without barrel bridge. Please note the length of the barrel window.
- 5mm version: These Buckings are compatible to all standard barrels with a HopUp window of 4,8 - 5,2mm. For particularly heavy BBs with a lot of energy (0.45g+ at 2.5J+) we recommend rather to reach for the 7mm version + tuning barrel, because 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, PPS FX7, TNT...). Due to the 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 the 7mm combination only from 0.45g + BBs at min. 2.5J to use.
Tensioner:
Our buckings are compatible with all common tensioners and levers. For best results we recommend to use FlatHop Tenioner or Lever.
Shooting in:
Like all other available buckings on the market, ours need to be shot in. A constant HopUp effect is achieved after 200 - 400 shots. (Depending on energy and bullet weight)
Avoid setting too much hop for the first 2 magazines, as the patch needs to settle in.
Compatibility:
We have tested our buckings in different systems, in this table we would like to provide you a short overview of compatibility.
Please note that there are many different VSR parts and systems on the market and it is not possible for us to test them all. If you have any further information here, we would be happy to receive an email.
