CYMA M1 Carbine disassembly

[t0l]

Hi, 

I recently purchased one of those $40 CYMA M1 spring guns, more for the novelty factor than anything else, and I was dismayed to discover that the trigger return spring was broke when it arrived. After some time just working around it by flicking my finger to get the trigger to go back in place, the weapon no longer cocks, and when I shake the weapon I can hear something small rattling around inside. I've since tried to take the whole thing apart, but the safety switch is blocking me from just lifting the whole receiver out of the stock. How do I properly/fully disassemble this so that I can further assess the issue?

EDIT: Meant to post this in the armory. Whoops.

I shifted this over to the proper thread. Typically it is not worth the trouble to disassemble inexpensive springers as upgrades aren't practical and their cost is so low. Generally when they fail it is because an internal plastic piece has broken and replacement pieces simply don't exist.

My suggestion with one of these would have been to immediately get with the retailer for a replacement. Of the 20 plus I have bought I had only one failure and that was after experimenting with a more powerful spring. I had a couple that had brass burrs in the barrels (easy fix) and all needed the barrels cleaned anyway.

Sorry you got a bad one but hopefully it can be replaced. I used my toes up one to try and create an AEG version but with no luck. (Simply too little room to work with)

When I took it apart I didn't take pictures of the process. It (and other springers) are definitely NOT designed with disassembly in mind.

Well, I got my replacement, and everything seems to work just fine. I'm a bit cautious about it, since there's something small rattling in the front handguard, but so far, I think it's not a lemon. This one also doesn't seem to be utterly coated in lubricant, which is also nice.

Thanks for your help.

The handguard is easy enough to remove without risky disassembly nightmares. Most likely there is a small screw rattling around. The handguard itself snaps into place with a tab that slides into a slot behind the hop up opening and a slide tab up at the front.

Hi, sorry for being away. Was busy with college stuff.

I'll open the handguard up and figure out what the problem is, if possible, this weekend, as I'll actually have time to take a breather.

Quick question, though. For the bayonet lug, are the only things holding it to the outer barrel the two little screws, or do I need to dremel it off?

[shiftysgarand]

The bayonet lug is molded into the outer barrel, you must Dremel it off to remove it. Those screws are either there to reinforce it or steady the inner barrel, and they do a pretty poor job at both.

[2nd Bat]

Shifty is spot on. The screws can easily be dremeled through. Once cut away you can file and sand it all to an acceptable shape. If the outer barrel then becomes unacceptably loose you can hold it snug with a wrap of friction tape or some Gen purpose glue. I only had a couple that required any support once the bayonet lug was removed.

Hey, sorry to bump this again. I think the hopup on my gun broke, since it just kinda scrolls freely instead of going through various "clicks" or whatever. Is there a fix for it if it's broken?

[2nd Bat]

Wow. How weird that you have had issues. Again with cheap springers if there is an issue typically they aren't fixable or worth the effort. It's interesting that I have had dozens of these which have been loaned out and subjected to field play with no functional breakage. They just seem to work and work and work. I have had some sites break and some magazines lost but otherwise they have been incredibly robust.

My broken one (heavy duty spring installed finally busted something) has been a parts mule for my other guns. I would suggest you buy a replacement.

[t0l]

Hey, it's me again. I've got some free time, finally, so I can put it into turning my (hop up-less) carbine into a display piece or something. Just got a few questions, this time.

First, how do I take the safety out? It's the only thing blocking me from just pulling the receiver out of the stock, and I can't figure out for the life of me as to how to take this little snap ring thing off the other side without busting it because I don't have the right tool set or something. Would a small snap ring remover make it easier?

Second, how would I take the orange tip off? I'm not sure exactly how it's attached to the barrel, but I'd like to pull it off.

Thanks.

For the safety, use needle nose pliers or a very small flathead screwdriver to pry the clip off perpendicular to the clip aka slide it out of the groove on the safety, don't bend it out. The C clip will spread enough to let it pop off and still go back on later.

The Orange tip can be broken off with pliers or something of the sort. It's brittle plastic and the barrel underneath is the proper shape without it

Hi guys I ordered an original ww2 surplus M1 Carbine stock and one of these CYMA m1 carbines. I want to take the stock off the airsoft gun and replace it with the real Springfield Armory stock. The stock came in the mail already but I have to wait another week for the airsoft m1 carbine to come in. Does anybody know what I will have to do to make the airsoft guts fit into the stock? If you have pictures if you've done it before that would be very helpful because I want to do as little cutting and shaving and fitting to this 1945 stock as possible.

[2nd Bat]

It is going to require some dremel work and precision fitting which is time consuming and often a bit frustrating. Assuming everything fits okay (it should). It should wind up being a great looking little gun.

A lot of time and expense for a cheap little Springer but no doubt a fun little project. Keep us posted on your progress.

hi guys, do you have any idea of the type of hopup bucking? is there something similar amongst the sniper or gas guns?
the original is hard to set up and perhaps i d like to change a barell for a precision one as well....
mine is chronoed to 115m/s and I d like to push it a little further and to bring more consistency into its performance - to be able to hit each shot the same spot...
