M16A1 US Colt made, free part set without barrel and bolt.
Used condition as pictured.
Butt stock and handguard can have typical cracks/tores. Lock-out release of the charging handle may be missing.
It is not allowed to mount demilled barrel, nor demilled bolt head into the receiver, because then you would have a complete decoration gun, which then would require EU licence demilisation certificate and stamping.
