DM9 bolt not moving completely

[Plexo]

every about 4th or 5th shot, the bolt doesn't move all the way. The LPR seems jacked up pretty high, possibly higher then i would like to have it set at... but i think its helping, if i lower it the bolt moves but never makes it...

The HPR is set with a Dwell of 22 to shoot at 290-300 The dwell, IMO should only help this situation so i dont know about turning it down.

i had it on 20 on sunday and it was fine (i compensated the increased dwell with a reduced HPR incase you were worried i'd mis-calculated my FPS)

try stripping and cleaning/ re lubing the LPR and the HPR as well as the bolt assembly

then reset the board to the default and reset the LPR settings, this vid should help:

hope this helps

before you try any of that, make sure you change the battery over... twice.
