This started life as a Mossberg 500 JIC Mariner 12 gauge shotgun. I added a pistol-grip forend, shell holder, heat shield, ghost sights and tactical flashlight mount.
Remington M1903-A4, a bolt-action .30-06 sniper rifle from 1943. My grandfather modified this rifle with a custom stock and a Leupold Vari-X II 2-7x telescopic sight.
Remington Model 1900. According to the serial number, this 12 gauge double-barrel shotgun was manufactured in 1904. It originally belonged to my grandfather's grandfather's brother, my great-great-great uncle. I went with a photographic style similar to the period in which the gun was made. And there are goats!
Crosman Phantom 1000X air rifle. This is no toy; it will fire a .177 lead pellet at 1000 feet per second (682 mph, just barely subsonic). I have a scope for this rifle, but I find it easier to use with just the iron sights. It's very light and feels great in the hands. I've primarily used it for shooting the pigeons that occasionally infest the barn.
Taurus Night Court Judge. Fires .45 Colt and .410 shotshells. I finally managed to find a holster for it, but I'd kind of like to find a Western-style belt to go with it. When I first got this revolver, ammo for it was extremely scarce, except for lead Cowboy Action Shooting loads, but now that people have figured out that Obama isn't going to take their guns away, the ammo shortage has ended and most stores have again started carrying .45 Colt JHP and +P rounds. With +P loading, the .45 Colt is actually more powerful than a .44 Magnum.
