I think that the Marlin X guns and the Remington 783s share the same barreled action design, just with different roll stamps and the knobs on the bolt handles are a little different. I like the Marlin X guns, but don't particularly care look of the 783 stock or trigger guard.

The Marlin plastic trigger guards can quickly/easily be swapped out for the metal trigger guards from the Marlin 981/983 series, perhaps the same swap could be done on the 783s.
