maybe a bit off topic... but I have one of two regular "truck guns"
1st is an old H&R folding 12 gauge that I customized, shortening the barrel & adding a screw type adjustable poly choke, which I added a fiber optic bead these old single shots fold so tightly, I could about fit it in a pool cue box... it's IMO, like those pocket fisherman poles they used to sell... I can shoot any number of shot, ball or slug loads out of my "big gun"
my 2nd is a Thompson Contender with an assortment of 10" barrels... one is my 45 Colt hunting barrel in 10", the 2nd is a custom 44 Hotshot barrel ( this is a shallow rifled barrel with a straight rifled choke tube that screws in the end... it was designed in the 60's to shoot 44 mag or 44 shot shells that used a huge plastic shot bulb that made them about the size of a .410 ) mine is converted to shoot 444 Marlin cases, which I load like brass .410 shells, or put 3-.375" lead round balls, or use light loads of 444 Marlin... the top sight on the shot barrel is fiber optic, plus it has a see through mount with a laser mounted, & under the barrel a tactical flashlight, & was designed to shoot skunks & other farm yard varmints after dark... I want to add a 3rd barrel to the set... something longer range... I thought maybe .223, but want to keep my barrels at 10"... so lately have been thinking about doing a fast twist 22 Hornet ( I have a couple guns I've put 22 Hornet chambers on 1 in 9" twist barrels, & have been loading up to 68 grain bullets in the 22 Hornet case )
all of these are currently getting dura coated to make them more rust resistant
& of course all are single shots... a long way from the AR platform, but with either cased in my truck, they don't look like anything worth stealing, & I could shoot or hunt just about anything
