Problem is you can't upgrade the internals, like most guns....pot metal innards are pot metal innards.....

Thats ok I just need a new Hop Up Chamber let me know if you know were I can get one. Thank you.

I'd try to write to Tokyo Model Company. They are pretty good with e-mail, give them the part number, see what they can do for you...

Sorry I forgot yes I Emailed them about an hour ago I hope they respond. Cant even get a reply from where I got it redwolfairsoft

They do exist... for Hi-Capa only, at this time (big surprise there. LOL.)

I've seen it happen to a TM G17 before as well

One major problem I've seen with a couple of them is the original ABS slide cracks at the front sight. Not chips and big gaping holes but hairline cracks from regular use. So who knows it may blow out in the future but that was what metal slides were made for.

This is very frustrating. Red wolf contacted me. He is checking on the part. Until then I will try & find a way to make this weak point on the hop up unit stronger then before. I cut away the break & cleaned it up. Made a new hook out of a thick steel sheet. I drilled a hole in the hop up unit. I will screw the hook down & J&B or epoxy in place.

When griding away at the stuff with my Dremal It seemed to be stronger then pot metal. It is just a very weak spot for the part that broke off. I almost think my new idea may be stronger.

It's still pot metal, even if it may not seem like it to you. Marui just uses a higher aluminum content in their alloy. There's higher nickel content as well, which is why it doesn't oxidize as easily as high zinc alloys.

Glock 18c HopUp repair
 

So I am not getting much help. This is sad because this was the reason I chose to go with a Tokyo Marui in the first place. I have had the pistol for less then a month I contacted Redwolfairsoft & they tell me I will have to pay just to see if they can order the part from Marui. So I have been working on a temp fix until I can get the right part. This new steel part may be stronger then the original part. The peace that broke off is not held on by much at all. Photo's of this are on the 1st page. With the stronger recoil & hammer springs I installed. This is putting more stress on the hopup unit hook that looks the barrel down to the frame. To make it even more stronger & permanent I have it J&B welded clamped in a vise with a pair of vice grips. We will see what happens.

Sorry, never happened to me. Not my fault shit breaks on you? Kinda hard for me to help when I have no idea how that even happened/could happen.

I never said it was anyones fault. Just frustrating you know? Thats why I am working on a fix & posting this stuff in case it happens to anyone else. It would be nice to find a new part tho.

Drilled a hole in the hop up unit then threaded the hole with a screw. I cut the ends off the screw and cut a very small slot in it. Making a grub screw. Nothing can be sticking out the bottom of the hop up. I tested it with this alone & the gun fired perfectly for 75 rounds. Then the slide became ruff to rack. The gun would jam every other shot or so. This is because the barrel is only locked down on one side. I striped the gun to find my hook had bent up a tad bit. So I bent it back & filled the gap in with rosin core solder. Much more solid & should keep it from bending upward.

Hey guys, does anyone know if it's the Glock 17 Guarder frame that can fit unto the 18c or is there another one just for the Glock 18c ?

remember that problem I mentioned earlier about the front sight cracking and blowing out. Well guess what it just happened to me on a brand new G18c, not even 200 rounds in and it just went pop and the whole spring guide flies out...

What's up with that?
