THIS IS MY VERY FIRST GUN I USED FOR DEER HUNTING. ITS A SEARS AND ROEBUCK. I'M NOT SURE THE MANUFACTURE IS. ITS A MODEL # 200. MOD. THE BARREL HAS BEEN CUT DOWN BY A MACHINE SHOP AND DRILLED AND TAPPED FOR THE BB SIGHT ON THE END. THE BARREL MEASURES 20" APPROX. THIS IS THE WAY I'VE ALWAYS HUNTED WITH IT. IT CAN ALSO BE USED FOR A TACTICAL OR TRUNK GUN WITH SOME MORE MODIFACATIONS. WHAT EVER YOUR USE IS. VERY NICE AND CLEAN. IT HAS NOT BEEN DRILLED FOR A SCOPE. THANKS EMAIL WITH QUESTIONS.
