I don't know too much about much... but the 0 carrier sounds really tight. Possibly too tight to vent properly on a misfed ball?
All I got for now.
Helios body, rtp rail, xvalve, rpg intelli w splinter blade, apocalypse reg, ive got the lvlx set up with red spring 0 carrier, no shims, the rt on/off
Need more info..
Twist lock body? or? What size on/off pin? What other parts?
