VMP-1 Outer Barrel

A replacement for the original System 7 outer barrel and hop-up which allows the fitting of standard AEG inner barrels and hop-up rubbers. System 7 parts are hard to come by these days and this allows you to upgrade and uprate your inner barrel with the hop-up rubber of your choice.

Features a novel rotary adjustable hop system and a selection of different strength nubs so you can hop whatever weight of BB you need to.  Alternately there is a TDC version, adjustable by hex key, but to adjust it in-situ you need to drill through the bolt and upper receiver.

Printed from super tough Black ABS like engineering resin from Resione, it can take a beating and is still strong enough that you can sand and buff out the marks afterwards. 

Available as just the outer barrel with rotary hop system for you to fit your own choice of hop-up rubber and inner barrel, or as a full kit prefitted with a Unicorn 138mm AEG Barrel and a 4uantum Friction Pro AEG bucking, pre-assembled and ready to drop in.
