Maple Leaf Glock hop unit and inner barrel set. Suitable for WE & TM this set is designed for the G17/G18C Series pistols and includes a 97mm 6.02 precision barrel, Monster 75 Deg hop rubber, hop unit, hop arm, I key and adjustment wheel.
This is the latest version and is suitable for WE GEN 3, 4 and GEN5.
Fitting note: It is very important to ensure that the hop rubber is fitted correctly to the inner barrel. When fitted, place a BB into the hop rubber and if fitted correctly it will not fall through. Check this again when fitting the hop arm, then the I key and finally the side plate. If the hop rubber is not fitted correctly then the BB will fall through unless maximum pressure is applied via the adjustment wheel. This is not a fault, it is a fitting issue. If not confident then consult with a local Airsoft Technician.
