TEKNO Posted July 22, 2010 Report Share Posted July 22, 2010 Any one know any tricks to stop the god dam spring in the blow back unit from getting crushed? Just got new internals, and rebuilt the blow back unit, 1st set of springs last 60 rounds, 2nd set last about 100rnds before getting crushed. HAve the KSC version with ready fighter nozzle. Thanks Quote Link to post Share on other sites
bbstriker Posted July 22, 2010 Report Share Posted July 22, 2010 (edited) I had the same problem with the Ready fighter nozzle. The issue seems to be with the springs on the nozzle slipping off. If you cut a small groove on each plastic bit that the spring attaches to on the nozzle, then the spring loop is latched (under tension) onto the nozzle bit-the problem should go away. It's worked for me. Good luck. Edited July 22, 2010 by bbstriker Quote Link to post Share on other sites
3vi1-D4n Posted July 22, 2010 Report Share Posted July 22, 2010 Super glue/locktite, or as BBstriker said, cut a small notch. Similar issues on some blowback pistols, I usually just super glue the spring onto the blowback chamber.. Quote Link to post Share on other sites
TEKNO Posted July 23, 2010 Report Share Posted July 23, 2010 cheers chap - nothes cut - will glue it just for double safty =] Quote Link to post Share on other sites
TEKNO Posted July 26, 2010 Report Share Posted July 26, 2010 Oh my ghey - its happened again - W.T. Actual F is going on. 4 sets of springs crushed in as many days. I give up. Is the KWA version any easier on the springs - i love this gun to bits (more than my PTW!!) when it works but this is ridiculas =/ Should maybe have stopped running it on green, but needed to to get any decent power out of it @ the temperates in Ireland - aint exactly warm =] Quote Link to post Share on other sites
kruck Posted August 5, 2010 Report Share Posted August 5, 2010 Turns out I ordered the wrong size. The stock screw is M4x10, I ordered a load of now useless M3x16. Ah well, I received the M4x16 today and that has resolved that issue. Unfortunately it has started misfeeding again. Time for a new hop up rubber methinks, at least I'll be able to take it apart this time... Quote Link to post Share on other sites

My KWA springs snapped after around 500 rnds. Quote Link to post Share on other sites
TEKNO Posted August 6, 2010 Report Share Posted August 6, 2010 it was the ready fighter springs i was using - there were glued in place on the nozzle - and still mamanged to kill them selves =[ Quote Link to post Share on other sites
aznriptide859 Posted August 6, 2010 Report Share Posted August 6, 2010 Hmmm...I found with my RF nozzle my MP7 wouldn't feed at all. I'm still using my KWA stock nozzle...maybe you should pick one of those up instead lol. Quote Link to post Share on other sites
TEKNO Posted August 7, 2010 Report Share Posted August 7, 2010 There is still 1 spring attached - and its going like the clappers, i wonder how long it'll last - RoF went up too =] Quote Link to post Share on other sites
kullwarrior Posted August 12, 2010 Report Share Posted August 12, 2010 How strong would the KSC Mp7 Taiwan be when you have the Shooter Design Rocket valve install? I'm wondering because my gov't think if the gun doesn't shoot hot enough it's dangerous (<430fps on 0.2g), if it's too hot it's dangerous too. (500fps+ & 5.7J+) Quote Link to post Share on other sites
kolumbo69 Posted August 13, 2010 Report Share Posted August 13, 2010 Is RA tech selling the npas kit again for the Mp7 or is it stil on the back burner? Quote Link to post Share on other sites
GingaNinga Posted August 13, 2010 Report Share Posted August 13, 2010 (edited) My MP7 was delivered, without issue, to my door about a month ago. I have been playing with it the past few weeks and my testing on HFC gas has had me right on the 1 Joule limit. With .2 BB I am shooting around 97-98m/s. I have yet to break 100 m/s so it is compliant. This has also been in very hot and humid weather as it is summer time here in Japan. I am hoping that these numbers will drop a touch as it starts to cool down. With .25 BBs the gun is hitting between 85-90 m/s. I had a single 100 m/s shot as well, so with .25 BBs I end up breaking the 1 Joule law here in Japan. I am going to have to get an RA-tech NPAS I guess As with everyone's reports, this thing is a blast to shoot, and is very well built. I was able to buy 3 Japanese KSC 40 round magazines and a three mag pouch, so I am set. I was going to try it this weekend, but I think I will hold off until I get the NPAS so that I don't have any legal issues to deal with. Here is the mag pouch...

Crimson Posted August 19, 2010 Report Share Posted August 19, 2010 Made by Ghost Gear, the clothing division of Laylax. The pouches i had made are better designed than that i had pouches just like that but the wall of the mag stoper on the mag kept geting caught on the mag pouch, I think the way mine are designed are the best, you dont even need to secure them too Guys have you seen this : http://shop.ehobbyasia.com/dytac-mp7-qd-silencer-with-tri-lug-flashider-black.html Too bad its not in stock would have bought it in a flash !

aznriptide859 Posted August 19, 2010 Report Share Posted August 19, 2010 I'm guessing it's out of stock during that huge DYTAC sale they had. Quote Link to post Share on other sites
kruck Posted August 19, 2010 Report Share Posted August 19, 2010 Cause of the bolt jams discovered. The four little screws on the bolt, sometimes would come loose and jam against the rails, solution was just to rack the bolt till it came free. Making sure they're in tight, add a little loctite if needed and it's all sorted. Just waiting for some more propane to arrive and I'll do some thorough testing, make sure I don't need a(nother) new hop rubber. Can't wait to skirmish this again, it has been far too long (I've had to use AEGs three times in woodland!! ). I have a little headcam footage of my last skirmish with it in woodland, camera stops recording after a couple of minutes of contact but it recorded the first few kills of a massive streak I've actually had more problems this past 2 months with AEGs than I've had total with the MP7 Quote Link to post Share on other sites
aznriptide859 Posted August 19, 2010 Report Share Posted August 19, 2010 Word...besides the original return springs snapping, I've never had an issue with the gun in the past 8 months I've owned it XD. Quote Link to post Share on other sites
GingaNinga Posted August 21, 2010 Report Share Posted August 21, 2010 @Crimson, Sorry, I don't recall seeing your pouches. Are they here in the thread? Really don't want to read all 70 pages again. Can you point me to them? Thanks. Quote Link to post Share on other sites
gerryg Posted August 23, 2010 Report Share Posted August 23, 2010 Hi folks, long time reader, first time poster here! I've run into a problem with my TW KSC, I was running the mp7 stock (apart from npas, which I'm not impressed with to be honest) but I stupidly added the hard kick to the gun. It worked away fine for a shoot and after that I noticed that the bolt was finding it hard to cycle but mostly wasn't releasing. Having looked at the bottom of the bolt, there was evidence of unnatural wear on the left hand side. When I took out the innards it seems as if the the hammer release mech on the left hand side isn't releasing in sync with the right side. It will release with a small amount of force and I'm guessing that the mech is slightly bent? Have any of you have had similar issues with the mp7? Many thanks!!

Crimson Posted August 23, 2010 Report Share Posted August 23, 2010 I have never had any problems at all what so ever with my mp7 (knocks on wood) @Crimson, Sorry, I don't recall seeing your pouches. Are they here in the thread? Really don't want to read all 70 pages again. Can you point me to them? Thanks. yeah they are there somewhere Its quicker to just take new pictures: Quote Link to post Share on other sites
gerryg Posted August 28, 2010 Report Share Posted August 28, 2010 Ok, further to my previous post, I figured out what was catching the bolt. The hard rubber pad that sits on the butt plate had come loose and was sitting just above the pistol grip. Needless to say it's well and truly bonded now but I'd image the regular applications of silicone oil might have loosened it in the 1st place? Anyhow, now that's sorted, does anyone know if anywhere has the 40rd mags in stock? Quote Link to post Share on other sites
jdizzle921 Posted August 31, 2010 Report Share Posted August 31, 2010 Just picked one of these up from a buddy a few days ago and the thing is a blast to shoot. Probably one of, if not the best gas gun I've owned in terms of functionality and overall skirmishing ability. Never before have I had a GBB that could fire 177 "Playable" (IE: Enough FPS/Range to tag someone while playing) shots on one magazine fill. I was able to get through about 50 pages or so and aside from a NPAS and some of the Rocket valves, are there any other upgrades some of you gentlemen have found helpful in your MP7?
