Cyma Thompson Problem

If it's the stock nozzle, I would certainly not touch it. The problem is elsewhere. Could throw off your seal with the bucking.

I just got in, I'll play around with it this weekend and post back later if I figure anything out. Thanks again guys.

This was actually my gun originally. (didn't know it was having this issue when I sold it)... They are king arm mags, and yes, silicone in the mag and filling thematic few times is a very good idea. Couldn't find the hicap to go with it, so he doesn't have it. That's about all I can add help-wise... Never had any other issues with it, nothing should be broken in it, but I suppose it's possible...

Also everything internal is stock on it.

Thanks for the added info. I actually got a chance to look at it tonight after all. I tried the silicone in the mags but it didn't really do much. I not sure about the filing of the nozzle at least not yet. What I did find is the nozzle seems to stick out just a hair more when fired on semi then on auto. I compared it with the distance the nozzle sticks out on my AK and it is about the same in auto but more in semi. I am wondering if the tappet plate is worn in some way. I saw some for V6 mech and they are not that much so I will probibly order one and it can't hurt to replace it . Holding the gun upside down did nothing as far as improving feed but you never know till you try.

Just a bit of a follow up as I've had some time to play around with the Thompson. I did the silcone as meantioned last night and as of last night it made no diffrence. But I got home to night and popped the same mag in and I guess the airsoft gods decided to be kind because she worked in semi. I put in an unsilconed mag and it still worked but not as good. Now something else I did was misted a little silcone in the feed throat of the hopup so maybe that did something. Anyway it works, so thanks again folks.
