blobface Posted January 2, 2014 Report Share Posted January 2, 2014 It's definitely pretty tough, I'd say tougher than the G5 mags... especially after 20 rounds. Quote Link to post Share on other sites
calbur20 Posted January 2, 2014 Author Report Share Posted January 2, 2014 Extreme pain in the *albatross* to load bbs in. You'll just have to resign yourself to the fact that you'll be sometimes loading around 20 bbs in the mags once in a while. Quote Link to post Share on other sites
blobface Posted January 2, 2014 Report Share Posted January 2, 2014 Yeah, I just manage to load 26 into my mag as an experiment, and sacairsoftsn00py you owe me a right index finger, I don't think I can use mine for a while. Quote Link to post Share on other sites
Zereck Posted January 2, 2014 Report Share Posted January 2, 2014 A single stack mag is harder to load? How hard are those spring? Especially that GHK mag springs are usually pretty hard and need a while to break in. Quote Link to post Share on other sites
rusTORK Posted January 2, 2014 Report Share Posted January 2, 2014 It can be a bit softer if remove metal spacer from bottom. You can easy detect it by sharking magazine up ad down. 1 Quote Link to post Share on other sites
renegadecow Posted January 3, 2014 Report Share Posted January 3, 2014 They used 0.50mm wire for the spring which is just about as thick as TM uses... for their double stack mags. Single stack VSR-10s for example use 0.30mm wire only. Loading the UMP by hand feels like loading 8 cartridges in a 7 round 1911 magazine. Using the spring from VSR-10 mags will definitely work and fit more bbs, but I didn't find out if it had enough tension to trip the bolt stop. Quote Link to post Share on other sites
blobface Posted January 3, 2014 Report Share Posted January 3, 2014 Just came back from a game, it does work pretty well, although it's hardly fair as a Hong Kong winter is about 20c at the moment. Actually, did you guys get the small speed loader adapter with your UMPs? It's like a 10x10x15mm lid that goes over the mag, I found that with that adapter I was able to load the mags pretty easily, I didn't try it before and resorted to using the normal thing that swings out.

DarkLite Posted January 4, 2014 Report Share Posted January 4, 2014 Can't you guys clip a few coils off the spring? Quote Link to post Share on other sites
steelfallenangel Posted January 30, 2014 Report Share Posted January 30, 2014 I finally got one, got it off Bunnyworkshop and they did it for a pretty good price including the top rail and suppressor, they also offered to fix all the mags for me upon purchasing them... but I am genuinely surprised by the performance, kicks super hard for such a small gun, even with the valve release set forward, wonder how well it'd work in the cold when I get back to the UK though, but all in all, I'm really happy with it so far. I"ve heard good things about that site. But don't really know anyone that has bought from them stateside. I know they're based in china but they carter to a much highly quality product than other ACM company's correct? Quote Link to post Share on other sites
blobface Posted January 30, 2014 Report Share Posted January 30, 2014 (edited) I"ve heard good things about that site. *Off Topic* Bunnyworkshop, based in Hong Kong, they mainly specialise in GBBs and custom work, they've got a mill, lathe, welder and a CNC machine on the pipeline, it's mainly ran by one guy who does most of the custom work, and 2-3 others to help him, they only really sell stuff they're interested in. They do custom kydex holster as well, I had one made for my XDM + Surefire X300, gave them the spec and got the holster in 2 weeks, fits well.

steelfallenangel Posted February 1, 2014 Report Share Posted February 1, 2014 Good to know. If I ever decide to trade in my G&G UMG for the VFC UMP (hopefully after the stock gun is abit better) I know where to get one. Quote Link to post Share on other sites
Hopna Posted April 21, 2014 Report Share Posted April 21, 2014 I'm starting to get interested in this gun, so I have a few questions. 1. First of all, are there any parts that tend to break really fast and need to be upgraded in order to make it skirmishable? 2. Are there any shops in Europe that have upgrades/spares for this gun? I've looked at multiple stores and I can't really find it. 3. Any upgrades that are highly recommended to enhance it's performance? I'd gladly sacrifice some recoil to make it more reliable/efficient. I've already looked on multiple sites, but I can't find that much about the UMP. I guess the MP5 and HK416 are more popular. Thanks in advance. Quote Link to post Share on other sites
rusTORK Posted April 21, 2014 Report Share Posted April 21, 2014 3. Any upgrades that are highly recommended to enhance it's performance? I'd gladly sacrifice some recoil to make it more reliable/efficient. 1st, your should look which seals on your magazine/magazines (look for bottom seal). VFC released enhanced bottom seal for UMP 45. Your may find it on WGC, just type in search bar "VFC UMP". This thing really help a lot! If magazine keep leak from top need disassemble and re-assemble top part of it. There is an o-ring between parts #30 and #34. I am recommend to assemble it by open stand and rotate each screw by 45 degree one by one to find best seal. Don't overtight! Your can't insert it after. 2nd, check your loading muzzle. VFC released muzzle version 2. It's have two o-ring seals instead of one and holes at the back. I am recommend to buy assembled version (it's direct drop-in), just b'coz your only have 1 ring on your default muzzle. 3rd, set recoil on low. I am also installed Azimuth Valve (2.6mm), but not sure i am really should to do it. Your have to be sure, that default one is dead to do so. What i am got at the end: 1. Magazine don't leak at all; 2. 380 FPS with 0,20 g BB and green gas, fast ROF and still hard kick recoil. Quote Link to post Share on other sites
Hopna Posted April 21, 2014 Report Share Posted April 21, 2014 Sounds like it doesn't take that much effort to make it work well. Thanks a lot for the response, as you've really helped me . Quote Link to post Share on other sites
rusTORK Posted April 21, 2014 Report Share Posted April 21, 2014 (edited) Here is small VFC manual about magazine disassembling. Also, your may install new Outer Barrel from Crusader made of steel. Another plus from it - it's have got proper markings! But, it's almost impossible to install small part from inside outer barrel: This part fixing in place inner barrel inside outer barrel. And the problem is - Crusader outer barrel don't have rifling inside for this part! Solution is simple - your need small part of thin rubber hose. Cut it approx 20-30mm and stretch on inner barrel. It will fix inner barrel inside outer barrel best way. Data for rubber hose: Outer diameter of inner barrel: 8.50mm Inner Diameter of Outer Barrel: 10.90mm You may also need to fill markings on Crusader outer barrel with gold color. It will really look cool. Here is original real steel barrel: Same with Bolt: Edited April 21, 2014 by rusTORK 1 Quote Link to post Share on other sites
Hopna Posted April 21, 2014 Report Share Posted April 21, 2014 Ah, nice. That doesn't seem to be that hard at all. It will probably take some weeks before I'll order one, but atleast now I know how to make it work well. Thanks again. Quote Link to post Share on other sites
rusTORK Posted April 21, 2014 Report Share Posted April 21, 2014 Ah, nice. That doesn't seem to be that hard at all. No, not hard at all. Just need patience and proper screw driver (VFC screws are soft). Quote Link to post Share on other sites

emp3ror86 Posted May 20, 2014 Report Share Posted May 20, 2014 I asked VFC about possible CO2 magazine plans. They do not have any, but they said they might consider it. Quote Link to post Share on other sites
rusTORK Posted May 20, 2014 Report Share Posted May 20, 2014 (edited) They usually don't have plans. I am asked them about MP5K, but PDW version (both: ready weapon and a kit). Same respond, no result. Edited May 20, 2014 by rusTORK Quote Link to post Share on other sites
emp3ror86 Posted May 20, 2014 Report Share Posted May 20, 2014 Perhaps if enough people bug them with it they will consider it seriously. Quote Link to post Share on other sites
Horsem4n Posted May 20, 2014 Report Share Posted May 20, 2014 (edited) If I was going to tackle the system, being the ump, I would get a cache of mags for the warm days and build an externally gassed high cap for the cold days. Edited May 20, 2014 by Horsem4n Quote Link to post Share on other sites
