RT Pro Choking problems

[SoYo-MoFo]

I have an RT pro with a lvl 10 kit and ULE body. Recently, it has been getting some problems. When you try to rapid fire, the sear ping goes all the way out, but when you pull the trigger, the gun chokes and the bolt only moves halfway. You have to wait for the sear pin to click all the way out before you can fire the next shot. Here are some of the things i tried, but to no avail:

I tried changing the spring to a smaller one, to reduce the tension, but that did not work.

I tried changing the carrier to a larger one to see if it was the bolt getting stuck, but that did not work (i also thoroughly lubricated the gun before use). Oddly enough, the gun works with a no.2, 1.5, and .5 carrier, but the no.1 carrier leaks.

I pulled the sear pin further back in, to ensure that the trigger wasnt blocking it from coming all the way back out, but the sear pin does not fully click after every shot.

My guess was that the on/off assembly is getting stuck and unable to come out. I took it out and it seems a little bit sticky, so i lubricated it but it still had the same problem.

Any help or suggestions would be appreciated. thank you.

cant figure it out

I can't seem to figure out whether it is the level 10 or simply my valve. I swapped out every combination of parts from my level 10; i changed out all the shims, going from 0 to 3 shims, but that didnt help. i went through 5 different carriers, checking carefully for any o-ring damage, but that didnt help. I tried 4 different spring sizes, but that didnt help either. The gun is unable to fully cycle and the sear pin gets stuck. I am convinced it is my on/off assembly, but i don't know whats wrong with it or how to fix it. Please, any help would be great.

what's your velocity at?

Have you tried oiling the valve?

Yes, of course i thoroughly lubricated the valve. I am shooting at a normal 260-280, its just the gun likes to choke and not cycle fully.

oh, i fixed mine now. I oiled on/off pin, make sure YOU OIL THE REG ASSEMBLY, and i oiled lx carrier oring, and added 1 shim, and i was good to go

Have you checked the tank? It might be having the problem. Try putting it on another gun and see if you get the same shootdown. I had a similar problem and it turned out to be a bad spring pack in my flatline.
