The Madbull Hard Blue hopup bucking is made from soft 60 degree rubber which allow them to be installed more easily and more easy to adjust properly. The softer material provides a better grip and will cause less FPS drop than traditional harder hopup buckings. The bucking is the part that contacts the BB as it passes through the hopup chamber and produces friction on the top of the BB which causes backspin which allows the BB to be more stable in flight and increase the range by producing lift. Hopup buckings are a wear and tear part and should be replaced as often as possible and every time you replace your inner barrel. Installed a used bucking and result in small tears which will eventually lead to other issues. Properly maintaining and replacing worn parts will keep your AEG operational for a very long time.

Warning: We at AirRattle.com recommend all upgrade / repair parts are installed by a professional as additional upgrades and/or custom fitting may be required. It is the responsibility of the customer to ensure the part is compatible with their gun prior to purchase. We are not responsible for any damage caused during or after installation and are installed at customer�s discretion.

4 of 5 Good Hop-up Bucking March 6, 2014
Reviewer: Mark B. from Hampton, VA United States  
I have used these hop-up buckings in the past & have always had good results from them. I would recommend them for any AEG that is shooting no more than 400 fps.
