The Maple Leaf Wonder Hop Up Rubber 75° for VSR-10 & GBB is the perfect bracket for your VSR-10 or GBB airsoft pistol.
As for the VSR-10 & GBB Buckings, Maple Leaf has released this Wonder Bucking alongside the 2 variants Autobot and Decepticon. The main difference from the Autobot and Decepticon fittings is that the Wonder fitting has a small guide rail on the left and right of the bullet, which ensures that the bullet is perfectly centered in the inner barrel.
This bucking is available in 50, 60, 70, 75 and 80°, which says something about the hardness of the rubber. If you play with a lighter ball you can choose the softer bucking, if you play with a heavy ball you can choose a harder bucking. The joule value in combination with the weight of the ball also influences the surface.
If you are using a heavy bullet (e.g. 0.40g) and your VSR has a joule value of around 2.3, you should choose a slightly harder bucking so that the bucking life is longer.
Due to the heavy weight and hard impact, a soft hanger will wear out more quickly.
If you look at the number of degrees in which Maple Leaf fittings are available, you could say that 50 and 60° fittings are perfect for GBB pistols and the 70° fittings and above are perfect for the VSR-10. (Exception: GBB rifles).
