The market is in your favor. Mossberg`s still hot. Condition looks nice and the .22Mag is back in favor. Don`t think peep is original but many options were available during Mossberg`s production. Besides the front sight, did/doe`s it have mounting holes for a rear barrel sight.

 

Yes i believe it does added a new photo

 

Either to the OP or anybody who can tell....approximately what year is that rifle?

 

I have no idea

 

I don't know the year but the last one I saw at the LGS was $250. And I should have bought it. But then I never should have sold mine to my worthless son in law!

 

Book says it was made from 1959- 1984.
NIB-$335
EX-$228
GD-$136
Pep sight and sling added after it was bought.
It came with open sights.

 

Optioned 640 Chuckster`s were drilled and tapped to accept receiver sights. What`s the sight marked (makers name)

 

it says mossberg on the side

 

The S330 peepsight is an option on Mossberg. 22 rifles of the later period. Most of my Mossies are the earlier period, using the S130. They have different receiver diameters, thus aren't interchangeable.
My 640KD Chuckster wears a scope. It has the standard barrel mounted rear sight.
An okay shooter, but not great. Stiff trigger, not adjustable. A good reliable rifle. I paid $175 for it, but that was 20 years ago.

 

What's the difference between a 640kd and a chuckster?
