Standard Manufacturing Switch-Gun

The Standard Manufacturing Switch-Gun is a transformer of a firearm that folds in half for concealment. The .22 Magnum revolver folds into its polymer grip and, when folded, it is a little smaller than most cell phones. Drawing the pistol is as simple as retrieving it and pressing the release button, causing it to flip into place like an automatic switchblade folding knife. Once deployed, you have 5 rounds of .22 WMR ready for single-action fire. 

Iver Johnson 1911A1 Carbine

Up next is another unusual handgun… or wait, rifle… ugh, both? Technically, yes, the Iver Johnson 1911A1 Carbine is just that, a designated carbine. But, I think we can all agree it’s just a 1911 with a longer 16-inch barrel and added stock. It even accepts standard 1911 .45 magazines. The classic 1911 iron sights are minimal, especially for “rifle” applications, but you can’t beat that lightweight and crisp trigger. Though it is not the most practical firearm on the list, the 1911A1 carbine is sure to bring a smile to your face and turn some heads at the range. 

Standard Manufacturing DP-12

The first of its kind, Standard Manufacturing’s DP-12 is a premium self-defense shotgun that is one beefy chink of steel. With two 18.5-inch barrels and two magazine tubes, this pump-action 12-gauge shotgun quickly fires 16 rounds (14+2) when fully loaded. This one-of-a-kind shotgun produces extreme firepower and consistent reliability. Further, the spreader choke tubes achieve a devastating pattern at 25 yards and feature Tru-Choke thread patterns for additional compatible muzzle attachments. The DP-12 shotgun features a generous amount of rail space for mounting plenty of accessories. 

Diamondback Sidekick

The Diamondback Sidekick may look just like a normal cowboy-style single-action revolver, but it holds a secret, it’s really a double-action/single-action piece. With both .22 LR and .22 WMR cylinders that can be easily swapped, the Sidekick gives you 9 rounds of your chosen load. This 4.5-inch barrel revolver is perfect for plinking, small game hunting, or even competition shooting. 

Ohio Ordnance Works 1918 BAR

The Browning Automatic Rifle (BAR) model 1918 is one of the most iconic firearms in history. This Ohio Ordnance Works 1918 BAR is a semi-auto reproduction version manufactured with some original WWI and WWII parts. The receiver is constructed of high-quality 8629 steel casting and has been carburized and induction heat-treated for long life and hard use. The castings are built from modern state-of-the-art CNC machining and every rifle is fully assembled, test-fired, and re-inspected.

Kel-Tec P50

Looking for a space-age gun from the future? We’ve got the next best thing, the Kel-Tec P50. The P50 is a 5.7x28mm semi-auto pistol that holds 50 rounds in the FN P90-style magazine. It is designed with a unique recoil system that is soft shooting and easy to handle. Additionally, the pistol features a full Picatinny top rail for optics mounting and short rail on bottom for mounting lights, lasers, and accessories. The P50 is capable of accepting a folding stock or arm brace, but be sure to look into the legal requirements. 

Spikes Tactical Samurai AR Lower

Although it’s not a complete firearm, it is classified as one. This Spikes Tactical Samurai stripped lower receiver is precision-machined from aircraft-grade billet 7075-T6 aluminum to internal military specifications and dimensions. Bullet pictographs allow for quick identification of the safety’s position and the samurai helmet machined into the magazine well gives your AR a unique look that is sure to get attention at the range. The Samurai stripped lower is the perfect choice for your next AR-15 build and is sure to have all your friends seething with jealousy! 

Ohio Ordnance Works M2-SLR .50 BMG

Based on the iconic Browning M2 machine gun, this civilian legal semi-automatic version will absolutely drop jaws at the range and put a smile on your face. It’s not too often you find yourself able to purchase a belt fed semi-automatic rifle, much less a belt fed .50 BMG chambered rifle. Now you can own a piece of history, literally, thanks to Ohio Ordnance Works. Each M2-SLR rifle is treated to a one of a kind production run and is produced with the highest quality materials and test-fired to confirm function. 

ALTOR 9mm Pistol

Although this next firearm is rather unique, it’s certainly not very complex. The ALTOR 9mm is a single-shot pistol that holds one round of ammunition. The break-action design features unmatched simplicity and foolproof operation, consisting of only two parts to load and fire. Although, this oddball fires on the release of the trigger. That’s right, pull the trigger to stage the striker and then release to fire. This takes some getting used to. This lightweight pistol has mostly polymer construction with a stainless steel barrel, coming in at just 10.5 ounces. This is a bare-bones firearm with rudimentary sights and a push-button safety designed to come in at an inexpensive price point. 

Rhineland Arms FG-9 Alpine

Let’s go back in time and take a look at the FG-9 from Rhineland Arms. The design of this unique rifle is based on the FG-42, an iconic German paratrooper rifle from WWII. Instead of being chambered for the heavy-recoiling original 8mm rifle cartridge and using impossible to find magazines, the FG-9 is chambered in 9mm Luger and uses plentiful AR SMG magazines. The mags still feed from the side like the original rifle, but now eject brass from the bottom, making this FG-9 a more ambidextrous design compared to the FG-42. 

The top of the receiver is equipped with a Picatinny rail for your favorite optics and the rifle features modified M-Lok attachments on the lower rail for bipods and other accessories. Further, the FG-9 sports a vintage appearing wooden handguard for the classic look one would expect.
