These were the standard commercial Winchester Model 1200 shotguns produced during the late 1960s and early-mid 1970s that were purchased and adapted for the military with a trench type bayonet lug/heat shield and U.S. marked. By the time most of these were delivered to the U.S. Military, the Vietnam War was nearing its end, and very few are believed to have made it overseas to Southeast Asia. Some of these remained in service and saw use in Grenada, Panama, the Persian Gulf, Somalia, Iraq and Afghanistan. Most were destroyed after their military service, leading to their scarcity today, with sparse government records of contract deliveries. The barrel is equipped with a six hole pattern heat shield with the bayonet lug adapter marked with part number "11686389" on the front end, secured to the barrel with three screws. The bayonet lug on this shotgun is sized for use with a M1917 bayonet, which remained in service through the time this gun would have been in use. The barrel is marked as cylinder choke and with 2 3/4 inch chamber, with "U.S." above the standard markings, and the frame is "US" marked on the bottom below the serial number. Blue/black anodized alloy frame, trigger housing and loading gate, blued magazine tube, parkerized steel barrel, heat shield/bayonet adapter and bolt. Fitted with an extended forearm and pistol grip stock with a Winchester branded hard rubber buttplate. 14 inch length of pull.

Exceptionally fine, retains 98% plus arsenal parkerized finish on the barrel, heat shield/bayonet adapter and bolt, 99% original matte blue/black anodized finish on the receiver, trigger guard and loading gate, 85% original blue finish on the magazine tube with some light cycling wear, numerous scattered small dings on the bolt, and some light handling marks. Wood is also excellent with a few scattered mild dents and scratches and crisp defined edges. Mechanically excellent. This high condition example of a desirable Vietnam era U.S. marked Winchester Model 1200 trench shotgun is the missing piece to any advanced U.S. Military firearms collection!
