Hello,
new to the forum but hoping for some advice, I recently picked up a M2000 the previous owner was having trouble with and i'm hoping to get it working again but every time I release the bolt it will only come ahead about half way and hangs up, I can reach in and manually push the lifter down then it will come ahead all the way, I have had it apart several times cleaning any burrs and checking everything I can think of but just cant tell were it is hanging up between the trigger assembly and the bottom of the bolt, has this ever been a issue brought up?. Thanks in advance.
