I have used maple leaf bucking since it apear on the market. Amazing product and amazing design. My experience with this type of hop up bucking exceed all my expectations. Recently I have upgraded an airsoft sniper gun. The cheapest I found on the market. So first thing I replace the hop up bucking with Maple Leaf autobot 70d . Then a 6.04 inner barrel, an 90° piston and a spring guide with bearing. Spring was the original one and vendor state that crono supose to be 420 fps to 430fps. To my surprise the output at crono was 3.5 joule. With 0.45 bb. That exceed with far more then any field limits almost 1.3 joule over the limit. Now I learn over the years how to upgrade an airsoft sniper rifle, but I never beleive that I need to learn to downgrade one. And for me now that is the biggest challenge. If not the fps increase, then the range is super ok and stable. Minor deviation left or right that is given by imperfection of bb's interior( air pokets). Rage was around 116 meters. But that range was not lobbed . Straight line of site with power zoom 10x on my scope and a small ballistic trajectory. All the times bb was in my scope image and never leaves the scope width or highest. When I shot normaly I keep the crosshair on the same point until the bb lands in order to take corection for the next shot. Although it was a bit hard to follow and see the bb at the distance over 90m but on a black target color was fine. Stability and consistency given by Maple leaf autobot bucking is amazing. In my opinion is the best bucking on the market.
