Digicon Target Contender advice

[R34V3R]

Hello to all, I have recently come into possession a Digicon Target Contender (13 inch model) and i absolutely love it, its been my holy grail gun for as long as i can remember (or maybe since the last time i watched Hard Target). My only issue with it is the lack of a hop in it. For such a powerful piece (pushing 490 on green gas and .2's) the lack of range is annoying me, .36's and .43's extend the range but its barely getting past 150 feet before a the bb just nosedives for the deck (target shooting its great, but with having permission to run it as a sniper pistol i could ideally do with the range being extended).

 

Now KM Head still do an 8 inch tightbore with an SCS adjustable hop for the Target, but seeing as i cant read japanese and google translate is a pile of ****, is there a way i could "create" my own hop mod for it. I know its a bit of an ask but if anyone can help would be muchly appreciated. I can get pics done and up if referrence is needed.

Sounds like he did a fairly easy conversion.

ive seen that article, but it doesnt say how or what he did other than fit a "hop up barrel", im looking for some ideas as to how to go about it, other than slapping a barrel with a hop window in there and hop for the best.
