i will do the same…

From what i heard, some of the improvements Tony does to the guns he tunes, are precisely to eliminate that problem. He does the “valve oring mod” wich is making an inner cut on the front part of the valve to install an oring between the valve and the valve stem, and he replaces the breech oring with D90 viton ones, thats why you havent noticed this.

mhh, speaking of tony, i think ill drop him a line, to see if he can sell me the front part of the valve with the oring mod.

I replaced the ones in my gun with viton durex 90 ones. The breech does seem to fit a little tigher on the top hat when i close it.
But i still feel a light blast of air from that area when i fire. I guess now i need an “oring mod” for the valve.
This sort of thing is what pisses me off about AF guns. ¿why can AF do these things at the factory? 👿

Is this a common issue? I have an Talon Tuned Talon SS(.22) and had a Talon SS(.177) and Talon Tuned Talon(.20) and never noticed/experienced issues from the breech o rings…
