My favorite TV gun prompted me to run out & get one, back then it was $399 now its worth closer to $1,000. Thanks to Mr. T--
I love it when a Plan comes together
In Aliens (II) the Marines were armed with "standard 10mm caseless pulse rifles." They were made from an upper casing using a .45 caliber M1 Thompson submachine gun, the lower is a Remington 870 12-gauge pump shotgun with a Franchi SPAS-12 shotgun exterior put on it.
