Used and For Sale at The Firearm Files we have a Vintage Mossberg 500E .410 Gauge Pump Action Shotgun! This shotgun dates back to 1975 Production, by searching the serial number which is G703353.

Sellers Notes on Condition: This shotgun is in great Condition, we rate it at 97%. The finish is all original, original blued barrel, Black Receiver, original butt pad, and we do not see any cracks in the stock. There are a few scratches on the stock, please look over our detailed pictures before purchasing. The bore looks pristine, I dont see any rusting or pitting on the gun. The manual safety sits on the receiver top, so it is an ambi operating safety. This is a hard to find gun like you see it with the Engraved Receiver!
