Guns like these are hard to find in this area. A dealer I know had bought it 2 years ago but never put it up for sale so I bought it.

The dealer seemed to think the receiver and bolt face should be the same in the 410 as a 308 or 7.62 X 39. He had not done it before but compairing the two he did not see a problem. After I bought the gun I ask him if it counl be easily converted, much like the AR's, just to have 2 calibers for one gun.
