Thanks for your responses.
The gun was made in 1996. This last jam--empty lodged between bolt and receiver and facing forward--using Remington .223 ammo. Not 5.56.
Gun was not very dirty at all except for usual burnt powder residue in gas piston area. Have it cleaned and back together.
This gun has some kind of adjustment screw at front of gas piston area. It's out in the open requiring no disassembly to adjust it. What's the reason for this screw? I would guess to increase or decrease the amount of gas that works the action. Maybe this needs adjusting. How do you adjust this properly? This is located right above hole for sling swivel.
