High quality silicone hop rubber designed to replace the current hop rubber in your AEG. 
This particular hop rubber is made to be compatible with all standard AEG type barrels and hop units. The contact patch in a hop rubber is the part that actually contacts the BB and applies the back spin, the contact patch on the Maple Leaf Monster hop rubber range are designed with a wide flat diamond shaped contact patch meaning they apply a uniform amount of pressure across the top of the BB and also assists in keeping the BB true and central in the barrel. 
** Please note, whilst Macaron's are one of the most popular hop rubbers on the market, they will not simply "drop" into every AEG.  Please research compatiblity.  No returns can be made for hop rubbers which have been fitted.
