New Atp - Air Cylinder Is Sticking
Posted 22 May 2012 - 09:08 AM
My brand new ATP seems to have a very slow-moving air cylinder. Unlike all my other KWA handguns, where that cylinder nozzle will stick in the chamber until the slide pulls far enough back to release it, on the ATP it doesn't stick in there at all. I've lubed the rails where that plastic ram slides, but it just feels too tight.
The gun DOES fire, but I don't have a way to test the velocity to know whether the fps is being greatly compromised. I would have to assume that if that air cylinder pulls back from the chamber immediately, then it's not allowing the full charge of air to propel the BB, nor is it likely recoiling to the fullest.

how many times did you shoot it so far?

The oil supplied is the proper silicone oil to be used to maintain the KWA. It is a little thick but you are not supposed to use much oil anyways.
On the other hand, the silicone oil spray cans sold at most stores are likely to swell KWAs rubber seals and cause issues.

As for firing the gun, I've run about ten-mags through, and it does seem to shoot and function alright. Like I already mentioned, I don't know if the muzzle velocity is being compromised because I don't have one of those radar deals. But, I can get through a mag of BB's without the gas running out, and it seems to hit the target from about the same distance as I can with one of my trusted MK-series pistols.
The biggest thing I notice, is that it really tends to shoot left. But my rear sight is a hair left, and I didn't have luck moving it to the center as the glue is stronger than I would have thought (FAIL on that move, KWA). I'll need to strip the slide bare, and soak the thing in hot water to break that bond. Ugh.
