Tru-Hop High Performance Bucking (Gen 2)
The Tru-HopTM is a high quality, high performance, all weather hop-up bucking designed to significantly boost range and accuracy. This hop-up bucking is installed like any other hop-up bucking on the market and requires zero† modification for its use. Additionally, this bucking will give consistent high performance results in a very wide temperature range (-50°C to 230°C/ -58°F to 446°F). This means that you can expect the same range and accuracy regardless if you are playing in cold snow or out in a hot desert environment. Lastly, the material used in this hop-up bucking was chosen from an extensive list of options and was identified as the best choice due to multiple physical properties; one of which is the very high durability that allows the Tru-HopTM to withstand hundreds of thousands of rounds.

The Science Behind Tru-Hop
The secret to the performance boost lies with the concave contact patch inside of the Tru-HopTM bucking. This contact patch was actually designed from scratch and then tuned through numerous redesigns and experiments. The end result is a shape that maximizes performance and is backed by hours of testing, logging, and re-testing. One of the design goals of the internal contact patch was to maximize the amount of surface area that contacts the BB. This design has two main advantages. The first advantage comes from the increased amount of friction over the top of the BB due to a larger amount of material making contact with the surface. This friction allows the user to over-hop virtually any weight BB with minimal pressure from the hop-up arm. The second advantage is related to the first and will be more pronounced in a typical AEG (automatic electric gun). What happens here is that there is very little loss in muzzle FPS from increasing the hop-up. In other words, you can set your hop-up to the optimum setting for your desired flight path and still retain the full muzzle energy you get at zero hop-up. The loss in FPS an average AEG typically experiences with increasing hop-up pressure comes from the stock bucking nub temporarily retaining the BB while air pressure is built up during firing. During this time, some air is leaked at the bucking-nozzle interface which leads to less kinetic energy at ideal hop-up. In contrast, the Tru-HopTM bucking allows the BB to pass more freely during firing since little hop-up pressure is required. The air losses at the nozzle-bucking interface are therefore reduced and thus more energy is retained during firing. This all translates to farther range at your optimal flight path.
The second major design goal of the concave contact patch was to boost the accuracy of the airsoft gun. It was noticed that the shape of the concave patch changes as hop-up is applied. The final design had to compensate for this change in shape so that proper concavity can be maintained at the optimal hop-up setting. Hours of trial-and-error testing was put into tuning this feature alone so that the compatibility of the bucking was maximized across numerous BB brands. Other features of the bucking were thoroughly studied as well. Simply put, every aspect of this bucking has been designed and tested to yield the maximum amount of performance from an airsoft gun.
