kwa mp9 with issues please help

smitty564 · June 18th, 2012, 23:36

My somewhat new mp9r started giving me issues after running just a couple mags threw it.

Once you insert mag, pull back and let go of charging handle, it will load one bb into barrel like it should, but then after taking one shot on semi or full auto it will not load a second bb into barrel. Someone told me the loading nozzle is broken but it will load that first bb with no issues. What could this be causing it to fire blank after that one initial bb is loaded?

(The mag is new so it can't be the mag)

Take off the slide and check the loading nozzle to see if its broken, or if the rocket valve somehow came out or loose.

did you release the spring in the mag after you put bb's in it? cause ksc's lock when pulled all the way down.

There is a LOT of things that can go wrong with that gun...

When you fire, are you 100% certain that no BB i loaded on the next cycle?
Also, does the bolt goes all the way forward when returning or you have to cycle it manually to be able to pull the trigger?
Did you check the left side of the bolt for scratches to see if the bolt catch was not scraping/grinding on the bolt?

More info is needed. I had a hell of a ride with mine, I think I got all problems with that gun... By then end it was a crazy nice gun, but needed 4 months of work.
