Maple Leaf 6.01mm Crazy Jet Inner Barrel w/ Hop Up set for Marui/ WE 1911 GBB (113mm)
Suitable For Tokyo Marui /WE 1911 Series Airsoft Gas Blow Back 
Designed a barrel where the end is wider compared to the rest of the barrel.
At the end of the barrel the air will pass the BB and come out first and when the BB comes out of the barrel, the air stream pulls the BB in a so called jet stream.
This will have less resistance on the BB and will NOT decrease the velocity but increases Accuracy instead !
Included is the Maple Leaf hop-up which is touted to be one of the best aftermarket hop up chambers and bucking combos!

Diameter: 6.01mm
Length: 113mm
