This curious little module vexes even the most technically proficient minds amongst Airsofters it seems but as it is a PDI solution it is bound to do good things and given time and testing we shall see what the Airsoft community makes of it.
This is a hop-up chamber modification for the venerable Tokyo Marui VSR-10. Although a very understated weapon out of the box, the TM VSR-10 can be upgraded to epic proportions giving it the reputation as one of the most effective platforms for Airsoft sniper rifles.
This module effectively manifests in two ways. First of, it removes the VSR-10s compatibility with VSR-10 inner barrels instead making use of Tokyo Marui AEG barrels. This gives the user many more options of barrel lengths and types. Secondly, the hop-up unit uses a completely new kind of system which claims superior shot-to-shot constancy and much more sensitive adjustment.
Exactly how it works is not exactly known just yet but this hop-up unit is adjustable with not one but two adjustment bars allowing the user to fine tune the setting with far more sensitive, smaller increments then on normal hop-ups. The improved bucking also has holding ledges which claims to ensure a much better seal against the inner barrel for yet further improved performance.
This module comes with the hop-up chamber, chamber packing, tapered cylinder head, o-rings and screws; a complete set to drop into your VSR-10 and AEG inner barrel combination.
