Flat hop represents an innovative thinking in creating the spin of the BB, which is simply based on a longer contact surface between the BB and the hop-up bucking. The term flat hop is usually used in reference to the hop-up bucking, from which the nub that gives the BB its spin has been filed smooth. Thus we achieve aforementioned longer contact surface.
ECS aka Extended Contact Surface
The benefits of the longer contact surface can be maximized by using a compatible ECS contact patch and a tensioner. A properly installed Flat hop is, at its best, consisted of three separate parts, of which each one differs from the standard hop-up solutions in airsoft guns.

Why is the longer contact surface better?
Accuracy: longer contact surface offers a more even spin, which has a smaller variation between the shots. Small variables, like the unevenness of the BBs and the tightness of the gun affect less than when using a standard hop-up bucking. The accuracy means an increase to the more effective range. Often the maximum range of the gun also increases due to the longer contact surface, especially when used with a special contact patch.
Thanks to the longer contact surface, the nub that gives the spin to the BB doesn’t have to go so deep into the barrel when adjusting the hop-up. In other words, the obstacle (ECS contact patch) pushed into the barrel creates the spin more along the natural direction of the propagation of the BB, unlike the standard hop-up buckings, in which the nub touches the round on a shorter distance, if you look it from the side. Thus, the trajectory of the BB inside the barrel stays as straight as possible. This also reduces its wobbling inside the barrel and during flight. This also attributes to better accuracy and longer range.
The longer contact surface and the smaller obstacle in the barrel also increase the tolerance towards the BB quality variations. This means that the respective quality variations of the BBs affect the gun’s accuracy less.
ECS Contact Patch
ECS contact patch further improves the benefits of the longer contact surface. A better air tightness is achieved thanks to the separate contact patch, because the hop-up bucking can only be chosen by keeping an eye on for the seal of the mechanism of the hop-up. The contact patch is only working for the spin of the BB. The ECS contact patch also endures wear better than the Flat hop used as a nub, because the contact patch is thicker and doesn’t stretch as much while adjusting the hop-up.
A contact patch that is designed along the barrel’s wall, centers the BB before the shot and further balances the variation of the spin’s direction between shots. Without the ECS contact patch, the nub that creates the spin, is normally more straight, which means that the BB doesn’t necessarily end up in the middle of the barrel even when discharging. The varying level of performance between the BBs is enhanced especially with poor quality inner barrels and those with big diameters as well as poor quality BBs.
The material of the ECS contact patch has been chosen by keeping an eye on accuracy and durability. The life span of the contact patch is considerably longer than just with the thin Flat hop. ECS contact patch is also better suitable for colder circumstances than the standard hop-up buckings, because the contact patch won’t freeze like its predecessor. The effect is enhanced especially with heavier BBs and high upgrade levels.
About the installation
The ECS contact patch that is exactly the size of the inner barrel’s window ensures a smoothest and most effective trajectory for the BB, because the spin stays as steady as possible. We recommend reserving enough time for modifying the contact patch before final installation. Note also, that the ECS contact patch should be cut to size according to the measurement of the inner barrel window. The both sides of the contact patch should be filed that they follow the barrel’s inner and outer surface – thus you can achieve the best result.
We recommend an even 6 mm peg to help with the installation, with which the ECS contact patch is possible to be adjusted and installed to fit your barrel.
Tradesoft Flat hop ECS contact patch is suitable to be used in basically any spring, gas and electric-powered gun, with a hop-up mechanism. Some hop-up windows might need to be modified to be more rectangular, so that the installation of the contact patch is easier.
The length of the ECS contact patch is around 6 mm (hop-up windows are normally under 5 mm long). This ECS contact patch fits normal-length inner barrel windows for guns of all powers. For maximum accuracy and range we recommend the longer 10 mm ECS contact patch.
