Hey does anyone have one of these and have this problem? my ion leaks down the barrel with the uni blot and orange bolt stop in but it doesnt with the stock bolt/fire bolt and stock bolt stop. i have replaced the orings on the both the bolt and the stop does anyone know what is wrong?
One trick is to lower the input pressure - then slowly increase it while chrono-ing. You'll probably find you can lower the input pressure and still get a decent FPS out of it.
This 'may' stop it leaking down the bolt - as it cured my problem with a QEV install.
It could also be, that teh o-rings on teh stem of teh bolt, at teh back, arent broken in and isnt sealing correctly in teh back of the bolt tube bit thingy...try firing it a few times as well.
