Hey im pretty new here. i have had my minimag for 10 yrs it has level 7 with level 10 bolt and i only use compressed air through it, i was reading that if you change the old on/off assembly with an rt on/off assembly it will dramatically lighten the trigger pull as well as not changing the intergrity of the valve system. Im not sure exactly what the rt on/off is and how i go about obtaining one and installing it. Any help would much appreciated. thank you
