I've had my M2 for a couple of years and it's been a great 3 gun shotgun. It has served me well with few if any malfunctions.
Today while I was practicing my shotgun speed reloads (with dummy rounds) my M2 started randomly locking the shell lifter as if the cartridge drop lever had been depressed.
I'm just loading dummy rounds into the tube. The bolt is closed.
When I start loading dummy rounds sometimes after the first round is loaded, sometimes after the third, etc., there is a "click" and shell lifter is locked. To remedy I hit the bolt release button and resume reloading.
Details:
CRUMs welded lifter
recently cleaned the bolt (wiped down, but not oiled)
Any ideas?
Thanks in advance.
PS - I posted this on another forum but thought I'd try here too
