Introduced in 1967, the M16A1 (aka the Model 603) would be the standard issue rifle for the United States Army and Marine Corps until the 1980s. Developed from end-user feedback on the M16, the M16A1 introduced the "fenced" magazine catch to reduce the risk of accidentally ejecting the magazine during handling or movement, the forward assist upper receiver and bolt to help close a bolt that is obstructed by fouling or residue, and other minor adjustments. Post front and two-leaf peep rear sights, with an A1 flash hider on the "C MP CHROME BORE" marked barrel , triangular handguard, checkered pistol grip and fixed buttstock. The upper receiver has the A1 pattern low profile casing deflector and an oval shaped forward assist, and the lower has a fenced magazine catch and right handed "SAFE"/"SEMI"/"AUTO" selector. A "C" marked full auto bolt carrier is installed, with a "MP C" marked bolt head, both matte black finished. "VALLEY VIEW POLICE" has been carved into both sides of the buttstock, and an inventory tag for the Village of Valley View has been applied to the left side of the receiver; a suburb of Cleveland, Ohio, Valley View was incorporated in 1919 and had a population of 2034 at the 2010 Census. Four extra magazines are included along with manuals and other documents.

Excellent, with 97% plus original matte gray finish, showing some light handling marks and edge wear overall. Aside from the hand markings, the stock is also in excellent condition. Mechanically excellent.
