The X-Caliber Shotgun Gauge Adapter system is a set of inserts for break-action 12-gauge shotguns that allows you to fire just about all of the most popular cartridges in production, from .22 Long Rifle up to .308 Winchester.
It’s an 8-piece set of drop-in adapters that measure seven inches long each, and it comes with a carrying case. It’s got to be one of the most practical survivalist piece of kit we’ve seen in a long time. The adapters are rifled for accuracy.
Development of the X-Caliber system started late last year and now the first batch of pre-orders is coming in. Each set comes with an adapter for .22 Short and Long Rifle, .38 Special and .357 Magnum, 9mm, 45 ACP, .410 bore and .45 Long Colt, .223 Remington, 7.62×39mm and .308 Winchester.
This adds a huge amount of flexibility to your 12-gauge shotgun, which is already arguably the most versatile firearm in the world. Combined with this kit, that’s undoubtable.
Sure, it’s not as good as having a rifle chambered in .223 and it’s a lot bulkier than a .357 revolver, but it takes up a lot less space than ten guns and costs less, too. Each X-Caliber kit runs $450 and delivery times can be as long as two months, but for the prepper-minded, that’s got to be worth the wait.
“The adapters are easily stored in a heavy duty canvas case complete with MOLLE-compatible straps on the backside for easy mounting on your bug out pack. The X Caliber truly gives you options. You choose the right caliber for the task at hand. The X Caliber equals ten guns for the price of one, saving you money, and reducing weight in your pack. X Caliber gives you ten guns for the price of one, and the survival value … is priceless.”
X-Caliber system inventor Tim Ralston said to The Blaze, “It’s my version of the ultimate survival rifle.” He also pointed out that the demand for the kits has been very positive, even before he knew how it would be priced. “I said, ‘I don’t even know how much it costs yet’ and they said ‘I don’t care. With this system, you can pick the right ammo for the right time.”
Granted, it’s not ideal. The cartridge adapters are very short, particularly for .223 and .308, and you’re going to see a significant decrease in performance. And they remain single-shot and implement a manual extraction system called your fingers, but certainly make up for it with extensibility.
The concept isn’t entirely original. 12-gauge-to-20-gauge and 12-gauge-to-.22 adapters have been around for a long time, and some manufacturers have also made handgun cartridge adapters. But this takes things to a different level.
And most importantly, it gives you an excuse to pick up a Handi-Rifle if you don’t already own one.
