s85sss Posted January 9, 2010 Report Share Posted January 9, 2010 I'm getting 1.63J from my KSC Japan version, using a old KSC Glock 17 rocket valve, RF cylinder and RF #24 springs, and 0.3g BBs. Â do you have any malfunctions/issues running this kit? does it works flawless? Quote Link to post Share on other sites

kruck Posted January 10, 2010 Report Share Posted January 10, 2010 I just ordered KWA MP7 from ehobby Apart from WGCshop, where can I get the NPAS from? Â Quote Link to post Share on other sites
kdogg Posted January 10, 2010 Report Share Posted January 10, 2010 (edited) I was just talking to someone as an unnamed US based custom barrel company recently, they are about to release a KWA/KSC MP7 tight bore. It's a company everyone will recognize but they haven't officially mentioned it yet. Â Very soon though. Â Btw s85sss, the US Post Office just raised there prices to $13.50! Better change your signature! Edited January 10, 2010 by kdogg Quote Link to post Share on other sites
galactica Posted January 10, 2010 Report Share Posted January 10, 2010 Can you talk to them about doing an extended tb as well as a stock length? That'd be lovely. Ta. Quote Link to post Share on other sites

It's a company everyone will recognize but they haven't officially mentioned it yet. Great, keep us informed when this goes public. Â As Galactica says, if you have any influence, please encourage them to do one around 250mm. I doubt I would bother buying a stock length one but I'd definitely have a 250, especially if they did it as a kit, with silencer adapter. Â Â Greg. Quote Link to post Share on other sites
david pithers Posted January 12, 2010 Report Share Posted January 12, 2010 Just got my KWA MP7 through and extremly chuffed with the quality. Just a couple of questions though. I ordered a second mag with it, and im not sure which one it is but one of them keeps firing after ejecting all the bb's. One will lock back like it is supposed too. The other does not. Im guessing its the extra mag i ordered, although have no way of telling as they are visually identical. Also how do these puppies work with 134a? I managed to get a magfull off a mate and tried it and it seemed to run out of puff pretty quick. But that might have been the dodgy mag if thats the one i gassed  any help appreciated Quote Link to post Share on other sites
galactica Posted January 12, 2010 Report Share Posted January 12, 2010 examine the BB follower in each mag - it's the follower that makes lock-back happen. There's a post on the KWS USA forums about this. Quote Link to post Share on other sites
aznriptide859 Posted January 12, 2010 Report Share Posted January 12, 2010 Do you press the loading button after each time you load it? Quote Link to post Share on other sites
david pithers Posted January 12, 2010 Report Share Posted January 12, 2010 Thanks for mention about the KWA USA forum, but that seems to apply to mags that have been abused by letting the mag loader slide up and hit the top. This is a brand new mag, and i cant visually see a difference between the one that works and the one that does not. One thing i did notice is that when thumbing out the bb's, every now and then the bb's would not move up like there was no tension. I would have to slide the loader down slightly then back up and it would work. Again not sure if that was the locking mag or not. Have oiled em both for good measure. I reckon i press the button right, as one works consistently locking. Also when empty the bolt will lock when pulled back on both. Mysterious Quote Link to post Share on other sites
-l- Posted January 13, 2010 Report Share Posted January 13, 2010 Just a quick heads up, aluminum alloy bolt carrier is on the way. Produce by the same company who made the steel bolt carrier. Quote Link to post Share on other sites

Mysterious As Galactica rightly says, there is a notch on the bb follower that controls the lockback. Â Take the follower & spring out of the mag. It drops out of the bottom. Â Thoroughly clean the bb channel. You will be amazed how much poo comes out of that area, even on a 'brand-new' mag. Â While you have it out, you can check the bb follower to make sure it's ok. Â Earlier, you asked if they are ok on 134a. I ran mine on 134a back in September & it was ok but you may have problems in the lower temperatures. Fine on green of course, unless you have the ksc jap version, in which case you will eventually blow the nozzle & have to replace it with the ready fighter reinforced unit.

greg Posted January 15, 2010 Report Share Posted January 15, 2010 (edited) EUREKA! Â Finally got the barrel sorted. Â The TN barrel from WGC, for the M93R Auto, is in & running. Â Bonus was, that the barrel was 200mm (not 178mm as expected), 40mm longer than the original, falling just short of the end of the flash hider. Â Gun chronoes 395, .2g, @ 19C, which is about 30 up on the original barrel. Shot to shot consistency seems better, I think the hop rubber's seal is tighter but that's just conjecture. Â I can't see any improvement on the accuracy, which was great anyway. Possibly a bit better, definitely no worse, approx 12" groups at 50M. I can't be arsed to do proper side by sides with targets & that. Â The barrel did need slight modification, 3 bits of filing. About an hour in the shed to get it just right. Drop out the original, you'll work it out. Â So, if you are impatient for a tight bore, order one of these & get filing. Â Â Greg.

AirSoftNJ Posted January 16, 2010 Report Share Posted January 16, 2010 (edited) Nice Greg!  Let me Ask you Why Didnt you Just use a PDI 7 Inch Hi Capa Barrel? All the Specs are the Same as the TN Correct? Since it Basically a GBB in a Different Body    But I tried getting the outer barrel/inner barrel out. Can you Describe How to?  I tried Removing all the Rails and BCG and Undid the Pin to the Left of the Bolt Release and it only wiggled a little bit. All I see Now is Removing the Small (.5 Torx) Screw From the Bolt Catch  Can you Explain Greg if I am going in the right direction etc.  Thanks So Much  EDIT:  O Btw I think I found a Guide Correct Me if I am wrong  http://www.redwolfairsoft.com/redwolf/airs...il?reviewID=234 Edited January 16, 2010 by AirSoftNJ Quote Link to post Share on other sites
AirSoftNJ Posted January 16, 2010 Report Share Posted January 16, 2010 Also I think I may have Found a Hi-Flow Valve for the MP7, Â http://www.dentrinityshop.com/pr_details.jsp?pid=8330 Â I tool out my Old Valve and It Compared it to this one and They Look Pretty Much identical, Ill Gonna Gve it a Shot and Try it Out Quote Link to post Share on other sites
aznriptide859 Posted January 17, 2010 Report Share Posted January 17, 2010 Most KSC/KWA valves are interchangeable, but I HIGHLY doubt that is the case w/ the MP7. Quote Link to post Share on other sites

Kretschmer Posted January 17, 2010 Report Share Posted January 17, 2010 Thoroughly clean the bb channel. You will be amazed how much poo comes out of that area, even on a 'brand-new' mag.  Specially on a brand new mag... whole lotta poo.    Also my EdGi 6.00 stock length is coming already. I´ll let you know in a tenday.    Quote Link to post Share on other sites

axl Posted January 21, 2010 Report Share Posted January 21, 2010 I could use some help here guys. Are NovatCombat and XFire still the only choices for silencer adapters for the KSC MP7? Â Cheers, Axl Quote Link to post Share on other sites
