Bought A Used Kmp9, Fixing Her Up.
Posted 17 November 2011 - 07:37 PM
Overall the gun functions great. Noticed a couple of quirks though. Namely every so often when I push the bolt back into battery(occasionally it won't return into battery), sometimes pushing it forward causes the gun to discharge. Normal? Timing messed up? Another seperate occasion, I pulled the trigger and nothing happened, then probablly 10 seconds later it fired without the trigger being depressed. Again timing issue?
Hoping that these problems will dry up once I stretch out that spring.
In the mean time, the only problem that I can't seem to fix. The magazine likes to jam, no bb's I have will feed. These are quality ones at that. Excel .25s, airsoft elite .25s, and excel .20s are what i've tried none work, somewhere along the line in the stack they'll stop up. I ran some 1000 grit sand paper inside the channel to smooth out an imperfection. Too no avail. Any ideas to fix this? I'd rather not waste some 5000 bb's.

Stretched it out, no matter how slowly I let the bolt go back into battery, the trigger can still be engaged, scratch that problem!
I'll keep that in mind about the ksc's. The follower locks and releases easily, and does not hang up anywhere. Though it looks kind of worn, no deformations, or major dings.

Taken from my "amazing camera", i'll try and see if anything can be done about the quality. Unless you can see what you need to see..?

I'm barely getting one. Presently, following KWA's instructions to fill the mag until gas over flows. I haven't detected any leaks in the magazine, and the seal on it looks good. Its been cleaned and lubricated properly and chrono'd at around 380fps last I checked. What would be the parts that would affect gas efficiency in such a dramatic way?
About the only thing that I could think of would be that the loading nozzle appears slightly malformed. Having a raised edge on the upper part of the nozzle. Though the difference in dimension from that and a brand new nozzle are hardly noticeable. I wouldn't have thought that it would have made much of a difference.

Also, what brand is it? I have had many issues with Power Green gas. It's the one you need to screw on an adapter for. I won't use it anymore and the store I tech for won't carry it anymore.

Will attempt too, have to check the local airsoft store. In the meantime, I had a second fresh can of propane laying around and popped it on. Was able to get through a magazine and a half before it died down. Temperature around here is about 52 degrees F if thats any indication on how it may be doing?

Huh really? Thats great I guess. though alot of the reports I saw where saying that you would get more out of a magazine.
