BIOVAL BBB DImplex - Golfball Style BB

From PopularAirsoft.com

Official Press Release:

Hi,

Here are the latest tests we have run with the BBB DIMPLEX. I have also included the drawings of our first prototype. I have eliminated all the technical references from the drawings.

The tests were executed at the 100m underground rifle shooting range in Sarganz, Switzerland. So wind was not a factor. We used a stock Tokyo Marui VSR-10 Pro Sniper Version with a 6.1mm tight bore high performance Teflon coated barrel. Manufacturer specifications of this gun are MOA of 4cm from 10 meter range and maximum range is 50 meters without upgrades. The new barrel gave us slightly better performance than the stock.

The rifle was bolted to a bench rest so that it could not move at all. We used a barrel laser (it replaces the bolt assembly) to zero the rifle precisely in the centre of our target. Exactly 100 shots were fired for each of the 3 tests for a total of 300 shots of BBB 0.20g and 300 shots of the BBBDIMPLEX.

The 1st test was to check for an accuracy difference between normal BBB 0.20g and the BBBDIMPLEX. A paper target was placed at 10 meters and changed after every 10 shots were fired. The rifle was laser zeroed after every change of target. The results represent the average distance measured from the center of the target (where the laser dot landed) of every group of 10 shots fired. We achieved the TM stock specifications of the rifle using normal BBB 0.20g and improved that considerably using the BBBDIMPLEX.

The 2nd and 3rd test was designed to check for a distance difference between normal BBB 0.20g and the BBBDIMPLEX. One group of 200 shots (100 BBB 0.20g and 100 BBBDIMPLEX) fired without Hop Up and the other group of 100 shots fired with Hop Up(100 BBB 0.20g and 100 BBBDIMPLEX). Measurements were taken after every group of ten shots and then averaged out. Therefore, the results represent the average maximum distance each of the bbs travelled for every group of 10 fired. Again the TM stock specifications were achieved with the BBB 0.20g and a considerable improvement was noticed with the BBBDIMPLEX.We are working to refine our design, material and weight of the BBBDIMPLEX to achieve optimal results. Stand by ...

"SORBOTHANE, a proprietary visco-elastic polymer material that exhibits properties of both liquids (viscous solutions) and solids (elastic materials). It is polyether-based, polyurethane material or a combination of the properties of rubber, silicone, and polymers. It can absorb shock, and isolate vibration from an unusual high amount of energy from a spring. While many materials exhibit one of these characteristics, Sorbothane combines all of them in a stable material with a long fatigue life." - ARS(Japan)

Japanese engineers designed the SORBO pads that were used specifically for Airsoft, and wasn't really known until a few airsoft enthusiasts tried to test and proved the benefits of the "small wonder"... the result was exceptional. The SORBO pad has proven its worth. Its damping characteristics and cheap price can be a substitute for the silent piston heads (for the "silent operators"), and it eliminates the need for reinforced gearboxes when using High rated springs...

"To measure performance I used the Audacity audio recording program and a boom microphone. To compare the performance difference I recorded the sound of my AEG before installation. Being careful not to confound the results, I left the microphone in the same place from the initial recording and placed the AEG where I could easily replace once the installation was complete. Now since I do not have a video camera, I could not leave a microphone out in the yard to record the noise coming from the front of the AEG. This would simulate the noise heard by a target player. My recordings are from the left side of my AEG and are taken from within 24” of the gearbox... The performance of the sorbo pad was effective. I noticed a deeper tone in the piston head on cylinder head impact."
