An updated Lemat carbine. Make it a closed-top frame for strength and optics mounting options. Chamber it in modern cartridges. Make the shotgun barrel load like an M203 so it works with normal size shells. Offer it in two frame sizes, the smaller in .327 Federal Mag or .357 Maximum with a 20ga shotgun barrel, the larger in .445 Supermag or .460 S&W with 12ga.
