Duckling Posted August 21, 2009 Report Share Posted August 21, 2009 can we get some info with regards to the circumstances? type of gas, temperature...etc? Standart GreenGas. 19C Guarder 0.28g BB's. Wanted to fire off my 100 rounds of magazines, for the first time, and got to round 90... Firing bursts of 10-20 rounds. Link to post Share on other sites
Utty Posted August 22, 2009 Report Share Posted August 22, 2009 That's KSC ownership for ya. They claim that there KWA Mp7A1 is not the same as the KSC Mp7A1. And therefore they say, there cylinder do not fit my gun. Nice to find a company that don't have a clue to the product they are selling... They're full of it. Some time ago I also contacted KWA USA for a replacement barrel lock for my woeful M9 FMV, and sure enough I got a reply IN ALL CAPS: SURE THING BRO WELL SEND IT TO YA WE TAKE CREDIT CARD (not their actual wording, lol). Soo where do I go to make the credit card transfer? No reply. Link to post Share on other sites
infected Posted August 22, 2009 Report Share Posted August 22, 2009 Fyi, if you're trying to order parts for your KSC from KWA do the following. 1. Call, don't email. 2. Tell them you need KWA Part #____ for a KWA "insert model here". Use the KWA terminology not the KSC. Also, use the KWA part number (if they are different than the KSC). 3. Pay over the phone with your credit card. Done. I've ordered parts from them over the phone several times for my USP (prior to the system7/ns2 systems), with no problems.

Duckling Posted August 24, 2009 Report Share Posted August 24, 2009 I've ordered parts from them over the phone several times for my USP (prior to the system7/ns2 systems), with no problems. The problem with KWA-USA this time, were that they first clamid that the KSC and KWA Mp7A1 did not use the same parts. ... later they admitted that they did not have the parts in stock yet.

greg Posted August 24, 2009 Report Share Posted August 24, 2009 Looks like this is a common fault. I've heared of two (one first & the other second hand) & seen one with the exact same fault. I'm praying mine doesn't go this way. So disappointing because this is an otherwise very impressive bit of kit. Greg. Link to post Share on other sites

Korppi Posted August 24, 2009 Report Share Posted August 24, 2009 Well is there space for a buffer? Have shot excess of 5K out of bone stock old KSC M11 on propane before bolt giving up. Link to post Share on other sites
galactica Posted August 24, 2009 Report Share Posted August 24, 2009 5k doesn't sound like all that many rounds, really... this is looking very upsetting. 134a only then, is it? until some aftermarket cylinders arrive. Link to post Share on other sites

Korppi Posted August 24, 2009 Report Share Posted August 24, 2009 The m11 bolt is held together with screws and that is where it breaks, the screwholes. I haven't looked on to the mp7 bolt, maybe it can survive longer with buffer. I wouldn't dream of using m11 w/o one. Link to post Share on other sites

I haven't looked on to the mp7 bolt, maybe it can survive longer with buffer. I wouldn't dream of using m11 w/o one. The design of the mp7 looks *really* close to the mp5k they put out. I'm not surprised the nozzle died, as thats one of the first things you need to replace on the mp5k to make it work on green. Link to post Share on other sites
(V)atrix Posted August 24, 2009 Report Share Posted August 24, 2009 The design of the mp7 looks *really* close to the mp5k they put out. When did KSC put out an MP5k?! Link to post Share on other sites
Rob15 Posted August 24, 2009 Report Share Posted August 24, 2009 They didn't, i'm assuming he means the Maruzen MP5k, in which case it looks nothing like it (apart from the generic loading nozzle overall shape) and the loading nozzle in my Vz61 which is identical to the MP5k hasn't had any issues on green.

Duckling Posted August 24, 2009 Report Share Posted August 24, 2009 Well is there space for a buffer? The new Mp7A1 have a rubber buffer that stops the bolt. When did KSC put out an MP5k?! Never. The only Mp5K GBB is the Maruzen one, and that have the same gasssystem as the old Maruzen M11. It have no reassemblens to the workings of the KSC Mp7A1. The Mp5k GBB fires from an open bolt (The Real Steel don't). It has no cylinder valve. The hammer is a fixed part of the bolt. ... and is ######, but fun. IMHO. Link to post Share on other sites
Korppi Posted August 28, 2009 Report Share Posted August 28, 2009 The new Mp7A1 have a rubber buffer that stops the bolt. Ok, pad of rubber is good for rs but for a toy I use foam rubber which works quite differently than solid rubber. The pads in my macs are about an inch thick. How thick is the mp7 buffer?

MCXL Posted August 28, 2009 Report Share Posted August 28, 2009 The buffer is not the issue man, that would protect the rear of the bolt which is fine, the part that is breaking is the NOZZLE. That's on the FRONT of the bolt. From what I have seen it looks like its due to poor casting tolerances, so some nozzles are weaker then others and will burst. I'm sure that the nozzle will be made by aftermarket men, in fact if its presented to RA tech as something thats causing people problems I' m sure they will make one.

hendrix Posted August 28, 2009 Report Share Posted August 28, 2009 the higher prices are because of the import and export tariffs, thats it. Link to post Share on other sites
Korppi Posted August 28, 2009 Report Share Posted August 28, 2009 Oh I see there was a picture too. Ye, damage like that can't be helped. Gunsnguys have been pretty quick on the replacements but if the part is fundementally pos ratech or similar needs to step up :\ Link to post Share on other sites
galactica Posted August 30, 2009 Report Share Posted August 30, 2009 Interestingly, KWA USA are saying on their forum that their gun is reinforced for green gas where the KSC is not. Those interested might want to follow the review thread in the reviews section. Link to post Share on other sites
