Hey guys, I've recently purchased a Tokyo Marui mk23 and the hop up seems to be acting up. Using .2 gram bbs I get about 50 feet of range before they seem to fall (on max hop). When I take the slide off to adjust the hop wheel it seems to have worked itself all the way to the other side disengaging the hopup. If you guys could shed any light on this matter it would be greatly appreciated.

Clean it with rubbing alcohol - or better yet, take it apart and clean it with soap and water very thorough.
Also, use at least 0.25 or heavier BBs.
If still not enough hopup, bend that u shaped metal part that presses the hopup rubber.

Thanks for the advice, I tried doing that but it seems that the hop up wants to stay in the off position. I've ordered an ra tech hop up wheel and a maple leaf bucking in order to combat this problem.I've also researched this problem and it appears that the hopup wheel itself needs to be shimmed, I'll try all of these ideas and let you know how it goes.

#2 problem

Well since I was going to make a thread like this for my problem why waste this one I will post my problem. WhenIi filled my magazine up when I got the gun I took about 10 shots then it died all the gas was gone so I thought it was the magazine so I tried to fix it this didn't solve the problem I bought two new ones and those had the same problem when I would turn the barrel facing the ground I could see the propane shooting out the end like a fountain. I think the o-rings are dried out its brand new doesn't have 50 rounds through it should I take it to a tech or do something else what do you guys suggest? :bs:

Thanks,
Jacob

Any help is appreciated thanks guys.

sounds like a leak in your piston oring, or nozzle.
Try some lube around/in the nozzle area.

If its brand new, you might be able to go back to the shop for warrantee.

I cant take it back will cost me $50 to ship it to Japan. I will try to lube the o-ring but it might take me a while to figure out how to disassemble it and be comfortable with it.

It's pretty straight forward this video might help.

Thanks Big Red now let me ask this I know you dont want to answer these kinds of questions but I was just searching and it never showed which part the piston is and the o-ring.


Thanks,
Jacob

 

[Big Red]

I'm not quite sure about the piston/o-ring, I haven't needed to disassemble that (yet) haha. Sorry I couldn't help you Jake.

 

[Jakethetankslayer]

Thats fine you did plenty by trying to help so thats plenty.


Thanks,
Jacob

Update: Today I got the hop up to work! I swapped the stock hopup to the maple leaf monster bucking and added a maple leaf I key.
