Maple Leaf Glock hop unit with Crazy Jet inner barrel.
Suitable for WE VFC & TM this set is designed for the G17/G18C Series pistols and includes a 97mm 6.04 Crazy Jet inner barrel, hop rubber, hop unit, hop arm, I key and adjustment wheel.
Interesting concept which uses a gap towards the end of the inner barrel which allows some gas to pass the BB and then accelerate in front creating a cushion of moving gas for the BB to travel within.
In theory this should then create an improvement in range and accuracy.

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.
