Classic Army UMC (HK UMP) Thread [Please Read 1st Post]
 

Hi, I've recently (May 2010) purchased a Classic Army UMC.

I would just like to compile some helpful information concerning this AEG (for Past/Present/Future Users);

• a short list of PROs and CONs.

• some helpful links to stores/parts.

• reviews.

...anything informative really. Anyone with detailed information about flaws, mods or warnings is more than welcome to post valuable information.
I do not want this to become a discussion thread that will end up talking about how an M4 or an AK is better.

• PROs & CONs

- With your battery inserted, sometimes it gets in the way of the cocking handle; so if you need to access your hop-up on the fly.. well you may be caught shaking your AEG around like a retard with a disgruntled face.

- I would be careful if you like to crawl on the ground with this AEG, as the long mags could probably easily get caught in branches and although it feels solid, I'm not one to test HOW solid things are.
And it's just awkward to crawl with it anyways.. it's made for you to run and kneel.

- You're supposed to be able to clip the stock in the folded position, but you have to exert so much force to lift it on the clip, I would be VERY concerned about the hinge eventually breaking or cracking. This for now seems to be the only most serious flaw I've encountered, could probably be remedied with shortening the clip that holds the stock folded.

- Limited battery space. While I haven't looked for a compatible 9.6V (I like the rate of fire of a 8.4V), the compartment is barely much bigger than an 8.4V AK-style battery. This may be of concern to some who would like to use huge 2000+ mAh batteries or higher rates of fire. I'd jsut recommend carrying 2 1400/1600mAh batteries.

• Are G&G UMG and/or STAR UMP Mags compatible with the Classic Army UMC?

G&G High cap Mags work flawlessly, they are exactly the same as the Classic Army mags, do not pay attention to websites that say the opposite.

G&G also have 50-/100-round mags, which I recommend, because the 400+round high-caps are hell'a'noisy when you run around!

• Where can I find Tightbore Barrels and Extended barrels? Suppressors? If not by Classic Army, what other brands have good compatible parts?

While I haven't found anywhere that stores a interesting array of Classic Army parts, I would recommend looking at www.airsoftgi.com and www.redwolfairsoft.com as they seem to have some of the G&G UMG parts as well.



Remember to please keep your comments informative and to the point, thank you.

Does anyone know if umarex ump mags fit the classic army umc?

the umarex UMP is made by Ares and uses proprietary mags. the Classic Army UMP is a clone of the G&G version. so any G&G UMP mags, you can use with your CA UMP. but the Ares/umarex mags won't fit the CA/G&G UMP.

i have also tested this out at my friend's store with a CA UMP and Umarex UMP, the mags are not interchangeable. i own a CA UMP myself, and i wish they made mags that has the dummy rounds for the CA UMP too ;).

Thanks for the info, I almost ordered one, found a site that sells ca mags for a decent price. airsofthelper.com , anyone use them before?

Another question, does the umc use the same internals as the g36? I know it's a version 3 but are the nozzle, tappet plate and selector plate the same as g36?
Thanks

I know its been a few months, but did you end up purchasing the UMC mags from airsoft helper? And if so, did you receive them? I've read mixed reviews on the site and I am hesitant to order anything as I have been scammed before. I have a UMG myself and I don't want to have to buy 10 mags at 20-25$ a piece to get 500 rds, when I could buy 5. This is absurd for an AEG. Does anyone know if the Umarex mags can be modded to fit? Maybe cut off those fins?

Thank for your post

Hey how do I take off the flash hider so I can put a suppressor on to cover an extended inner barrel?

Do you think there will ever be a drum mag for the ca umc ?

I have my doubts about ca making drum mags. If g&g makes a drum to fit it, that would be your best route.
