The Maple Leaf Crazy Jet features a unique construction that creates a cushion of air surrounding the BB as it shoots out of the barrel. Thus, the system reduces barrel friction and inner barrel movement affecting the trajectory of the BB. Additionally, this allows the BB to consistently have a hop up spin for better stability and accuracy. However, FPS and distance may remain similar or differ from the stock AEG inner barrel that is previously installed on your rifle. Overall, the Maple Leaf Crazy Jet is a great choice for your Tokyo Marui VSR-10, JG BAR-10, FN-SPR, VFC M40A3 and other airsoft bolt action sniper rifles ready to hit your one perfect shot on your target.
