M93r crushed return springs: alternatives?

MultipleParadox · June 7th, 2011, 11:12

Hey guys,
finally received my loading nozzle to fix my KWA M93RII.
Assembled the thing, fired a mag or two, and the return springs crushed and broke :banghead:

I have ordered some at the same time than my nozzle, but they're too long; I'll try to cut them and use them but not sure it's going to work. I was wondering if there could be some kind of alternative to this? Like rubber bands or something?

So basically I'm looking for ideas and stuff

Thanks!

Halp? Anyone?
In all cases I'll try to find some rubberbands small enough and see. Will post my results if I do.

The good news is that KWA usually has the parts. Check with the US branch.

Surebets: Yeah I knew about that but they seems to have some problems stocking parts... It seems to take weeks/months before they stock an item they don't have anymore (I've been waiting for them to have some nozzle for 2 months... finally ordered what I needed from KevinMan.hk).

Thing is his springs (same part # than KWA's) were too long. I cut them and it works, for now.

I did try Rubber bands anyways, just for the heck of it and maybe having a viable solution for the future that would be faster/cheaper than to order more springs. I gave these bands a try, cut them to length and pierced a hole at each extremity so the "posts" on the block/nozzle can get through them. And turns out it worked marvellously well, until one of the bands got out of its post. Probably just a tension/length adjustment and it would have worked better.

I'm not sure if it was just me but I had a feeling that operation was better with the bands, as it has more tension than the springs. Now the question is about knowing if it puts too much stress on the plastic or not.

I'd just need to find a way to make sure they stay in place. I thought about epoxy and what not obviously but that would mean permanent and unremovable if anything goes wrong.

If anyone have some ideas to have them stay in place more efficiently...

Sorry that I have no useful info but KWA/KSC are real bad for that. Went through 3 sets of return springs on my m9 till I finally gave up and sold the piece of shit. "Built to outperform...er break"

I tried the rubber band idea, they end up usually stretching out and fall off the external cylinder and the gas chamber block. Nothing works better than the cylinder return springs.

I have a new set, I ordered 3 sets for my M9 PTP and I've used 2. When I spruce up the internals, I change everything from the hop up to the springs. PM me and I will sell you a pair (BNIB).

You can also order them directly from KWAUSA, just call them and place your order with the sales team. You can explain that you're from Canada and need replacement parts and such and they will help you out. You do need a credit card to complete your order and I also recommend making a replacement parts list and order everything at one time. Hop up, external cylinder, rocket valves, and springs. Most of these usually come in sets like a complete external cylinder set with rocket valve, springs, and pin.

I have to also state that I've had my M9 PTP for 3 years and I've been thru 2 sets of springs (one set is still fine but changed it anyway), 2 hop up rubbers (one rubber still fine but the hop up was acting up so I changed it), and now I need a gas chamber block as one of the arms broke - it still performs flawlessly but I still would like it changed. They are fantastic pistols you just need to give them a little love when they need it and if you don't know what you're doing, there will be a chance for future failure. When you replace the springs make sure to put a small dot of “Super Glue” in the spring posts to prevent them from falling off or misalignment in the slide.

Hope this helped...Sorry for the wall of text...

you can actually use bic lighter springs they use to push the flint buy the full size bic lighters and pull the top top off to expose the spring works for many nozzle recoil springs

These springs are different from what you described.

The springs in reference here are extention springs not compression springs.

These springs offer resistance to the blow back mechanism and return the external cylinder back to the gas chamber block.

They work in the opposite direction of a compression spring like the one in a Bic lighter.
