Original Colt M16A1 buttstock with rear sling swivel, buttplate and door assembly *Condition Very Good*.
These buttstocks have the storage compartment.
They may show minor dings from handling and the buttplates typically have a minor non structural crack from age.
They do not have the top buttcap screw.
The earlier M16A1 buttstocks are 1 inch shorter than the current M16A2 buttstocks.
This is a factory part removed from Colt M16A1 export rifles.
