Hi guys, just wondering what you guys would run as a tappet with 13:1ratio, lonex hi torque and 11.1v lipo. Was running fine with a standard lonex m4 aluminium nozzel then started "mis feeding" then wouldn't feed at all.. turns out the first contact point of the tappet was worn hence not retracting the nozzel fully. It was a new build with a new tappet fully shimmed and running fine at 350 fps and 22 rps for bout 1000rnds 0.2. Best tappet available for a v2 m4?
