The Maple Leaf Wonder Hop Up Rubber 80° for VSR-10 & GBB is the perfect bucking to use in your VSR-10 or GBB airsoft pistol.
As far as VSR-10 & GBB buckings are concerned, Maple Leaf has introduced this Wonder bucking on the market alongside the 2 variants Autobot and Decepticon. The main difference between this and the Autobot and Decepticon bucking is that the Wonder bucking has a small guide rail to the left and right of the bb, which ensures the bb is perfectly centred 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 bb you can choose the softer bucking, if you play with a heavy bb you can choose a harder bucking. Also, the Joule value in combination with the weight of the bb affects the bucking.
If you choose a heavy bb (e.g. 0.40gr) and your VSR shoots around 2.3 Joule, you may want to choose a slightly stiffer bucking so that the life of the bucking is longer.
Due to the high weight and hard impact value when using a soft bucking, it will wear out faster.
Looking at the number of degrees in which Maple Leaf buckings are available, you could say that 50 and 60° buckings are perfect for GBB pistols and the buckings from 70° are perfect for the VSR-10. (Exception on GBB rifles).
