The Scoremaster 511 has a 25" barrel, a one piece hardwood stock, and a blued metal finish.
As the Scoremaster 511 was manufactured before 1968, these rifles do not have serial numbers. A two or three letter date code (indicating manfacture date) is stamped on left side of the barrel next to the receiver.
- 511A (Standard; open sight mounted on the barrel)
- 511P (Peep sight mounted on the rear of the receiver)
- 511SB (Smoothbore for .22 LR shot cartridges)
- 511X (Improved sights)
