Maple Leaf Autobot Hop Up Rubber 50° for VSR-10 & GBB

The Maple Leaf Autobot Hop Up Rubber 50° for VSR-10 & GBB is specially designed for use in a GBB (Gas BlowBack) replica or VSR-10 Sniper rifle.

The Autobot Bucking from Maple Leaf has a specially shaped contact patch that allows you to get more distance with the bb but leave a little more accuracy. If you want more accuracy and less distance, you need the Decepticon bucking.

The number of degrees says something about the hardness of the rubber. 50 Degrees is the softest and 80 degrees the hardest. The different degrees of hardness can be used in different ways in your AEG.
It makes no sense to use the hardest bucking when it is around freezing point because the cold makes a bucking stiffer and therefore harder to adjust. It is precisely in cold temperatures that you want a softer bucking.

The hardness of the bucking is also linked to the weight of the bb you are playing with. You can easily use a 0.30gr bb on a 50 degree bucking but this will probably result in it needing to be replaced sooner than when using this weight on a 70 degree bucking.

In the end, it comes down to personal preference.
