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 (-50C to 230C/ -58F to 446F). 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.

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.

"I don't understand why more brick and mortar retailers are not pushing this product!
An amazing alternative to R-Hop modification to your barrel. Shoots laser beam straight, bb flight path now looks exactly like what you see on youtube r-hop videos.
Be very careful during installation, don't be afraid to use some lube to avoid tearing the bucking and then clean up the bucking after installation.
Drops right in, fit my madbull python v2 on a VFC SCAR-L, great air seal even with the funky proprietary hop up chamber.
Also fit my VFC 6.03 barrel with a rounded hop window just fine, again installed with the SCAR proprietary hop up chamber.

"I use this in three of my guns - P* Rifle 650mm, P* Rifle 450mm, and AEG rifle 650mm

There is not a bucking/spacer combo that will give you any better range - guaranteed. I've used everything from prommy soft to G&G green, and this gives you the best performance you can get with a straight drop in bucking - it performs as well as my spring VSR10 that has been r-hopped.
One thing to watch out for is the over-hop. Even on zero hop, some of my guns get a little too much hop, but there is no denying the absolutely monstrous range this bucking gives.

"This bucking setup works amazing I replaced my promy purple and flat hop nub in my prowin with this and I was not disappointed this is in my polarstar and I would definitely recommend this I was suprised how well it worked.
