Made with 28,30,and 32" barrels. 6-shot capacity. Odd take-down design. Suggested price in 1929 was $39.99.
Considering this is a gun designed by John M. Browning,it is a pretty good designed shotgun.
I bought one several years ago,and have really enjoyed it.It was made in the mid 1930's,and is in great condition.It's a Westernfield (Montgomery Wards)with a factory Poly Choke.
The takedown action is a work of engineering genius,it's a cam lock design,and works very well.
The earlier designed 520's have a double humpback receiver,and the later ones are a single humpback.
If you dry fire one of these guns,you have to put forward pressure on the forearm handle before you try to pump the action.There is a recoil activated bolt safety cam that lets the bolt be cycled after firing,but it stays in position blocking bolt movement if dry fired.
Top shotgun is my 520-
