Full Version: Cyma Cm032 Dmr Upgrade
Airsoft Forum > AirSoft Replicas, Tech Talk and Advice > Upgrades & Modifications
Toketsu
Alright, I'm planning on buying a CYMA cm032 in the near future and I'm planning on upgrading it to DMR specs. I've been researching for about 30+ hours by now and I think I have a decent idea of what I need for what I want to do. I know there's a lot of other threads out there containing information on upgrades just like this and I've read through most of them. I tend to be rather stubborn when it comes to things like this and I want to make sure what I'm doing is 100% correct. It would be a waste if I spent all this money on something that didn't work. Anyway, here's a list of what I have so far:

CYMA cm032 upgrade parts:

-Prometheus Version 3 Spring Guide with Ball Bearings http://www.airsoftgi.com/product_info.php?...roducts_id=3619
-Prometheus Nozzle for TM M14 http://www.airsoftgi.com/product_info.php?...products_id=606
-Guarder SP110 spring http://www.airsoftgi.com/product_info.php?...roducts_id=1071
-Prometheus Precision Inner Barrel for TM M14 http://www.airsoftgi.com/product_info.php?...roducts_id=2131
-Prometheus Hop Up Bucking (Soft Type) http://www.airsoftgi.com/product_info.php?...roducts_id=4693
-Systema Duracon piston head with bearings http://www.airsoftgi.com/product_info.php?...products_id=973
-G&P Polycarb Piston (White Color) http://www.airsoftgi.com/product_info.php?...roducts_id=1636
-TM EG1000 Short Motor http://www.airsoftextreme.com/store/index....roducts_id=2431
-Custom 9.6v 4/5sc battery with deans connectors
-MOSFET

From what I've read so far, these parts are needed for fps, accuracy, and durability. I know a SP110 spring might sound kind of weak for a DMR, but I value range and accuracy over FPS. FPS just gets the bb to its target faster in my opinion. The FPS limit for AEGs where I play is 400 FPS, which is also why I'm only upgrading to that limit. I want my gun to be durable and not crap out on me after buying a whole bunch of parts to upgrade it.

It might be overkill for just shooting up to 400 fps, but that's my question. Are there any parts that I might have to include, or any that I don't need? Any suggestions to what I should or shouldn't get are greatly appreciated!

-Prometheus Version 3 Spring Guide with Ball Bearings http://www.airsoftgi.com/product_info.php?...roducts_id=3619 Good choice I don't know if it will work or not though. Can some clearify this?
-Prometheus Nozzle for TM M14 http://www.airsoftgi.com/product_info.php?...products_id=606 Good choice
-Guarder SP110 spring http://www.airsoftgi.com/product_info.php?...roducts_id=1071 This spring(depending on how good your compression is) will put you over 400.
-Prometheus Precision Inner Barrel for TM M14 http://www.airsoftgi.com/product_info.php?...roducts_id=2131 Great choice.
-Prometheus Hop Up Bucking (Soft Type) http://www.airsoftgi.com/product_info.php?...roducts_id=4693 Get a Systema bucking along with a SCS from Edgi Custom, that's one of the best combinations.
-Systema Duracon piston head with bearings http://www.airsoftgi.com/product_info.php?...products_id=973 Having bearings is not really needed since you have a bearing spring guide, but still a good choice.
-G&P Polycarb Piston (White Color) http://www.airsoftgi.com/product_info.php?...roducts_id=1636 Good choice.
-TM EG1000 Short Motor http://www.airsoftextreme.com/store/index....roducts_id=2431 Good choice but for a shorter trigger response I would go with the ICS Turbo 3000
-Custom 9.6v 4/5sc battery with deans connectors Get Elite cells off of cheaperbatterypacks.com
-MOSFET Go to extreme-fire.com and look at their selelction.

You may not want to replace the stock TM hopup bucking. If you do, definitely make it a Systema. In either case, you want the SCS nub.

I'd be cautious with the Systema piston head. I've heard bad things about them breaking, although the Duracon ones are better than the Area 1000s. Also, no one, ever, needs bearings on both the piston head and spring guide, and using a non-bearing piston head will reduce the reciprocating mass, thus increasing rate of fire and FPS slightly (very slightly) and decreasing impact strain on the gearbox. Go with a Guarder or G&P Explosive non-bearing piston head.

If you're looking to save some money, spring guides are one place where it's safe to do so. As long as it's metal and has bearings, it doesn't have to be a top brand. Area 1000 or some other cheap bearing spring guide will be just fine.

The Prometheus nozzle is a good choice; the Guarder nozzles are at least as good, and some say better. They have an internal oring that helps compression.

Good choice on the piston. The Supercore or G&G SNC pistons are even better, but much more expensive and not really needed for 400fps.

The TM motor is perfectly fine, and reputed to be one of the more battery-efficient motors out there. A more powerful motor would, however, give a faster trigger response.

The Prometheus barrel is an excellent choice. EdGI Custom or PDI would be even better.

Again, for MOSFETs, www.extreme-fire.com is your best bet.

I realize you may not want to go the lipo route, but for the cost of one upgraded 9.6v 2200mAh 4/5 SC battery pack from cheapbatterypacks.com ($50.40), you can get an Esky balancing lipo charger with power adapter ($16 on ebay, item 320368022390), two GE Power 7.4v 15C 3000mAh lipo batteries ($15 + $9 shipping on eBay- item 270366510214), and some Deans connectors (search eBay, they're dirt cheap) to replace the current connectors on your gun and the Esky charger and the weird RC connectors on the lipos.

Thanks for the information! Where could I find a SCS nub and a G&P or Guarder Explosive non-bearing piston head? Also, do you or does anyone know of a decent break down guide for installing the bucking and nub on this particular hopup or something close?

You can get a SCS at Edgi Custom they don't have them listed, you have to e-mail or call them about it. You can get the piston head at Ehobbyasia

You might consider ordering these parts off of Ehobbyasia.com, it's usually a lot cheaper. (and they have all of these parts)

Not sure if the spring guide will work. I think you might need a V7 one. As mentioned, you don't need the expensive ones. An element spring guide will work fine. (ehobby)

I'd go Guarder because they have an O ring. If you decide to stick with the promy, barrel, and bucking, the Promy nozzle would probably work the best. (

Systema buckings plus H nubs or SCS' work very well with Promy/Edgi barrels. (works great with my edgi. I always hear it works great in promy barrels as well)

Piston- Good choice. I would replace the piston just to have peace of mind. If you have the cash, then I would upgrade the piston.

Guarder SP110 springs usually settle in at 380 fps or so. You can get 400 fps, but it takes really good compression.

Good choice on the barrel.

You don't need bearings on both sides, it's overkill. I use a G&P explosive piston head (non-bearing) and it works great.

I've always heard EG1000 motors are very reliable and perform great. Good choice.

IDK about the battery, but Cheapbatterypacks.com is a great place.

Mosfet is always a good idea.

Only thing I would add is a #14 O ring from home depot. Soak it in silicone for like a day, then stretch around the cylinder, and heat it with a lighter for like 10 seconds. (try to not let the fire touch the O ring)

Thanks for the advice! Couple of questions though, if I decide to go for an Edgi barrel, which barrel length should I get? I see 499mm and 509mm barrels. I know that the m14 uses a 500mm and possibly a 520mm, so I want to make sure I pick the right one. Also, if I decide to switch from a SP110 spring to an SP120, would I have add anymore parts to keep the durability or would the set up I have now be able to handle it?

And about your #14 O ring trick, would you happen to have a diagram or maybe a picture of some sort that shows where exactly on the cylinder I place the O ring?

Don't go lipo...... Too finicky. Go to cheapbatterypacks.com and make a battery.

You need a V7 spring guide, V3 won't work to my knowledge.

I'll stick with my original battery plan then. As for the spring guide, from all that I've read about the cm032 I believe CYMA uses a clone version 7 gearbox which is nearly Tokyo Marui compatible. However, I read that the clone gearbox uses a version 3 spring guide instead of a version 7 spring guide. I'll do some more research to be 100% sure.

Thanks.

The Prometheus M14 barrel is shorter than the stock CYMA barrel. My friend ordered it for his CYMA M14 and when we got it and compared that to the CYMA barrel we got a little worried we'd lose range from it being so short. I don't have the barrel in front of me but I can measure it later and get a pic with other barrels to compare it. My Prometheus M16 barrel isn't long enough but it is closer to the stock barrel than the one for the M14.

This is just something to keep in mind if you get it. I doubt it would hurt taht bad if you install it. You'll probably get better groupings at range than with the stock barrel.

Hmm..well the prometheus M14 barrel is 500mm, whereas the stock barrel is 520mm. I don't think 20mm will affect the range all that much, but I could be wrong. I was considering buying a Edgi tightbore barrel, but I had no idea which one to choose. Edgi doesn't have a barrel listed for just an M14. Under their AEG barrels there are 6.01mm and 6.03mm barrels.

Under 6.01mm there are two barrels I'm assuming I could choose; 509mm for M16A1/A2/VN, AUG and a 509mm for KWA KM16.

Under 6.03mm barrels I can choose 509mm M16A1/A2/VN, AUG

So, I'm assuming that the 509mm M16A1/A2/VN, AUG version would be compatible with the M14. Either way, both the Prometheus and Edgi barrels are shorter than the stock.

6.01 vs 6.03 is an old, old debate, with no conclusive answer yet. 6.01 is accepted to produce slightly higher velocities. Accuracy is a tossup, but the difference is slight in any case. Perhaps more opinions are in favor of the 6.03, but there are only opinions. If you intend to use Bioval BBs, which are very slightly smaller in diameter, you should probably get the 6.01.

Length-wise, yes, the 509mm M16/AUG barrel will be compatible. Or, you can contact EdGI about making you a custom barrel in whatever length you want. 11mm of length will produce very little difference in accuracy, but on the other hand I don't think EdGI's custom-cut barrels will be much more expensive at all than the production lengths.

If you do decide to get an EdGI barrel, ask them about porting. Ported barrels allow the excess air pressure behind the BB to vent out the side, instead of spurting out after the BB and potentially affecting its trajectory. EdGI's range tests showed a slight but consistent increase in accuracy with the ported barrels, probably not enough to be noticeable under skirmish conditions. However, it's only $5, so you may as well go for it.

The "bull" barrels listed on EdGI's website are thicker and heavier to reduce vibration. For the most part, bull barrel usage is limited to sniper rifles, as they may not fit into most AEGs, and the difference in accuracy will probably not be noticeable over the distances most AEGs are capable of.

Hope this helps,

Mac

Edit: One last thing...I've heard fairly good things about the CYMA M14 hopup, but as the Tokyo Marui M14 hopup unit is considered the best on the planet, you might want to get one of those. They're $30 off ehobbyasia.

Thanks! This information helps a lot. As for the barrel compatibility, I just recently read a couple articles that a 509mm M16/AUG barrel won't work because the barrel clip notch is cut differently and the bucking stabilizer notch is shorter on the M14. Which results in not being able to fit the barrel in the hopup chamber, and having to cut the bucking to length. I've read that Universal cut barrels are compatible with the most AEGs including the M14. So, I'm hoping EdGI uses a barrel cut on their barrels that are compatible with the cm032.

I think eventually I'll contact EdGI about making a custom 6.03mm/500mm barrel and ask them if the barrel cut is compatible, unless I get answer about that before I contact them. I'll also ask them about porting my barrel when the time comes, if I do decide to go this route.

I have plenty of time to do more research. I'm not planning on having this gun for a while since all the cm032's seem to be sold out still for the time being.

Thanks again for the info! Any more suggestions are still appreciated!

Cyma got raided by the Chinese government, airsoft is not allowed in China(Ironic?). Evike.com has them on pre-order if you really want one earlier than everyone else.
