BD Bore Up Cylinder And Cylinder Head Set For V2 Gearbox M4 M16

 

Suitable For AEG Version 2 Gearbox

Material: Stainless Steel

Weight: 55.00g

 

Increased bore size means greater air capacity and volume for propelling the BB forward.

This is a highly recommended upgrade for AEGs with lengthened barrels since you will 

need additional volume of air to propel the BB out of the longer barrel - to avoid back-pressure. 

 

These bore-up cylinders actually have the same external dimensions as a stock cylinder 

so they will fit into a standard gearbox.
