WIP: Upgrading Your Tokyo Marui Glock

[Kimbo]

My new TM Glock 17 wasn't cycling properly so I took it apart and found that the front screw post on the frame had exploded. After some reading I found out that this was pretty common. Crap.

In the picture you can see the 3 individual pieces of the screw post that busted off.

I went to home depot and got some #6x32 blind anchors and some #6x32 countersunk machine screws and tried a DIY frame fix. I cut out the remaining part of the post and roughed up the area with a file. I drilled out the existing front rail hole to accommodate the larger #6 screw, threaded the the blind anchor on and covered the thread hole with a tiny piece of tape so the JB weld wouldn't get in the hole. I put a bit of JB weld into the old post socket, just enough to hit the bottom of the anchor and set the rails into the frame and let set. I backed out the screw the next day then filled the remaining cavity with more JB weld. This is what it looked like after drying.

I trimmed the material off of the sides and where I got it a bit too high and reassembled. It was pretty quick to to and costs less than $15.

I have about 400 rounds through it and it seems to be working fine. I'm going to get a Guarder frame anyway, but I thought I'd be interesting to see how long it will work with this mod before it fails.

So I'm thinking if its something to do with high flow valves since the WE come stock with them. Note that I will only be listing the parts I have changed in the gun. With my previous parts my gun works completely fine.

Parts I recently Modified:

Guns Modify CNC BBU
Action 8MM bearing Hammer Set
Guarder 150% Hammer Spring
Ready Fighter SAI Flat Trigger Paired with WE trigger Bar (My stock TM trigger bar was Threadlocked to my Guns Modify Trigger)

Phil,

THE two bolded components are a red flag for me.
I would swap out some internal stock components to see which one is causing what.

I know for a fact that the GunsModify BBU can act a bit wonky with aftermarket parts. Specifically piston heads. lol.

But yeah. I think that bearing and BBU combo might not be acting correctly.
So just swap a stock BBU to test the functionality of your Action 8mm bearing. Then swap to the stock bearing, to check and see if the Gomodify BBU is acting correctly. That's what I would do....

OR

THere's isn't not enough blowback to lock you hammer to sear hooks. That means that your gun is essentially short stroking.

Improve your piston head seal. Increase the hammer spring tension. And if neccessary, downgrade your recoil spring tension...

This increases your gun's capacity for blowback operation. Good seals + less resistance during the rearward stroke gets you a charged hammer (theoratically)...

There might be something else at play that I'm overlooking but I would start there....

Thanks E!!! ill check that out!!!

Airsoft Surgeon Nozzle broke on me. Trying the Guns Modify nozzle, seems good, however it will not work with the AS Piston Head. The Airsoft Surgeon nozzles appear to be out of stock everywhere...

EDIT:

While the Gunsmodify Nozzle fits well with the stock TM piston head, it works even better with the Airsoft Surgeon piston head once an O-Ring Swap is made. Using the next smallest O-Ring out of a pack of 10 I bought at Canadian Tire, the perfect fitment is achieved with the AS Piston head- Not wobbly, but not too tight either. Snug would be a good way to describe it. Recoil seems to have improved slightly, I doubt this will increase FPS but I'll chrony tomorrow to see if it has.

TL;DR- Smaller O-Ring + AS Piston Head + Gunsmodify Nozzle = Win

I was dicking around with my g18c, and the slide got stuck. In the end I forced it off, but I ended up snapping my hammer in half.

I can't find a tm g18c hammer for now, would a g17 hammer work in its place?

Unless someone can sell me one, in which case, please pm me.

Thanks!

[e-luder]

No. They are incompatible. You need a G18c specific hammer.

[Animalmother]

Since the guide was posted. What can I do to make my glock 18c more reliable? I know the frame, what else? I don't use full auto anymore. I also have been using duster gas as I'm afraid to use green gas. Metal slide+guarder frame? Spring with buffer? I already have a guarder mag catch and hammer spring.

What a great thread! Thanks! Have anyone out there seen original TM Glock 17 hop-up chambers for sale in an Asia webshop?

I can only find aluminum ones, and I prefer the original heavy one or steel/copper ones. My current one cracked off the bottom lip that locks in the barrel.

There's a whole bunch of over seas retailers that carry the stock hop unit.
I'm looking at one right now.

I don't think they ever made steel/copper ones though....

Can someone tell me where I can purchase the PGC slide and barrel for the marui g26? I can not find it anywhere and my plastic stock barrel cracked :/

I believe they're discontinued.

Thanks, that could be why. Any idea where I can get a Shooter’s Design g26 marui slide and barrel?

[apilar]

If you find one over seas be careful of the importing rules. I have a feeling there is a restriction on importing barrels/slides that are less than 5 inches...

Happy hunting

[Dino7777]

Not much help I know, but I recently looked around for an upgrade of my G26 slide, and after much searching in the Asia shops I could only find Guarder ones, so I went with that. Not cheap compared to G17 slides.

Here it is with the stock slide.

[N.G.]

I ordered a Guarder frame & Prime G34 slide for my G18c. Was able to transfer all parts with no issues, except for the stock blow back unit. I filed the BBU a bit where I thought it was hitting. It looks like the BBU is all the way in, but, it covers the slide grooves. You can see this in the first picture below. I am starting to think they sent me a slide for another model glock. Any help will be greatly appreciated. Thoughts?
