For sale is a Stevens 620 12 gauge shotgun built up to resemble a trench gun by cutting down the barrel and attaching a heat shield/bayonet lug. NOT an original and appropriately priced as such. I bought the gun already converted, don't know who originally did it, but it looks well done. Fired ~20 rounds through it myself, fires and ejects as it should. $400, price is firm. Must go through FFL, buyer pays transfer fees.
