Have a surplus M1 carbine, last time out fired it empty, removed mag, opened bolt, let bolt close on empty chamber. Now the bolt won't open. Any advice before I start taking things apart? - dan

The forum consensus is to take a deadblow mallet to the operating rod handle if the gun is verified to have no bullet in the chamber
I do not own one an M1 Carbine and this is not my advice, just what I read
