IMO, that is an excellent gun for the money. Very tempting...U
The takedown is by rotating the lever at the front of the floorplate then the barreled action can be lifted from the stock.
The trigger guard and floorplate remain with the stock.
See the piece behind the top tang of the action? It is fastened by the rear screw behind the trigger guard and the action tang hooks into it. I think it is a similar idea to a hooked breech on a muzzle loader.

At least I think that is how it works...

Wonder if it really is an 8mm Mauser.
