This is just wrong on so many points...
Big and bulkier than required dimensions that negate any benefit of a short barreled PGO gun.
A short stroke hung shell waiting to happen with what is likely a flexible loopy handle.
The geometric forces not being likely very even and possibly even binding in various points of the travel causing uneven wear and tear on the mag tube and fore stock.
Picatinny rails in excess.
Another home offense shotgun with the silly breacher simulator on the muzzle.
A solution to a problem that hasn't and will likely never exist.
Gotta admit that Mossberg is really "gung ho" about "tactically assaulting" the wallets of mall ninjas the world 'round!!!
