Alright so I'm trying to figure this out. My retrovalve is leaking out the rear, I bought a new reg piston from Tuna last season and only put maybe 6 cases tops through it. It is leaking out the back again when ever the input is higher then 400-500psi into the gun. I replaced the o-rings on the valve pin, and the reg piston o-ring. The valve piston looks good, lightly oiled everything. Is there anyway to test if the reg piston is bad?
I had my brother over to look at it (AGD tech in his younger years) and we are both stumped
