After a G&G rotary hop unit or hop unit that feeds in arp9

[steverebo]

I saw something on negaive airsofts video's that i thought was pure genius, my arp9 is my cqb gun but i like to use it outdoors as well so im getting another barrel and hop made up with a 200mm barrel for outdoors and keep the 128mm for cqb.

 

I need a second hop unit for my arp9 but it's a fussy eater and will only feed reliably with the g&g rotary and not the ZCI rotary i have and I cannot find another g&g rotary in stock anywhere so I'm wondering if anyone either has knows anywhere that has some in stock or has a spare that I could purchase or if they know of any other hop units that feed reliably in an arp9

Could reach out to negative airsoft to see if he has any spare he's part with??

Do it right.

 

Swap the nozzle for one that feeds and seals on the zci unit, then build your two barrels on those.

 

Also be aware that those extra 7 centimetres of barrel will dramatically increase the muzzle energy, so your gun may end up being too hot.

I can't seem to get the ZCI to feed reliably on the arp9 if at all.

 

I have taken into consideration the jump in fps and have it tuned to 0.85 to 0.9j on my 128mm barrel which jumps to 1.6 to 1.7j on the 200mm barrel which is perfect for field use

Whilst not the quickest option , have you tried contacting G&G directly ? They will sell spare parts and shipping is reasonable 👍🏼

They actually have a parts website and it's out of stock there as well. Seems to be a very popular product

I meant 1.06 to 1.07j 1.6 would be fun though in an arp9 wonder how long it would last 😅
