Ten thousand rounds and the thing hasn't broken or run full auto due to a peened forward firing pin yet? Lord Have Mercy.
If it was bedded -- it ain't anymore. Rick is probably correct in stating that this rifle has been shot so much that the torque from the receiver has mashed the wood -- thus creating the 'canted upper receiver' effect. I haven't seen this happen though.
Short cycling on a 14 can be due to a number of things. Rack grade 14s break the roll pin securing the oprod guide to the barrel -- thus jamming the oprod to degrees. Failure to clean out the gas piston and plug is another cause. Failure to ensure the gas plug locking nut is tightened to the barrel then unturned until the gas plug can be screwed in. Loose gas plug is another cause. At times guys will inadvertently turn the gas cut off to close and thus no gas gets into the gas piston. I have seen 14s lose the gas cut off locking pin and lose the gas cut off itself -- causing short cycles or no cycles. Hmmm, let me think here. Bent oprod and weak oprod spring are two more, particularly after ten thousand rounds of 'any ammo'. Oh yes, loose gas tube assembly is another one.
Ten thousand rounds? Barrel is gone. Indicators of a shot out barrel? Poor accuracy. This isn't rocket science here. I bet you are getting good velocity though as you are probably missing about four inches of rifling. Soon you will have a paradox barrel.
My advice to Spartan is to have the entire rifle totally rebuilt. I mean every single thing and probably a new bolt as well.
