The butt stock would need a apecial adapter to be easily removed from a 2100, plus the pump tube is a lot longer than a 760.
Seen a guy use a 1377 barrel turned around so the reduced muzzle fit into the 760 breach block. Original 1377 breach cut off and that end crowned and supported by the 760 barrel band. A 760 rifled "snubby." Combine that with an allen head stock bolt instead of the wimpy phillips head bolt and there you have a short, easy to stash takedown rifle that also uses 5-round mags! Pretty cool! Add a compact scope or dot and BADDABINGBADDABOOM!
