We here at DefenseReview (DR) are always suckers for futuristic weapons, particularly handheld ones. So, when the Arcflash Labs GR-1 “Anvil” 8-stage semi-automatic high voltage Gauss rifle recently came to out attention, we were admittedly intrigued. While the GR-1 “Anvil” doesn’t really look ready for prime time, yet, it’s still very interesting, and worth a quick piece. It’s essentially a handheld electromagnetic rail gun capable of ” accelerating any ferromagnetic projectile (under 1/2″ in diameter) to 200+ fps, and can deliver up to 75 ft-lbs of muzzle energy.” And, while that may not make the GR-1 the best choice for home defense applications, it’s certainly going to make for some good gunpowder-free fun on the range, or in your basement–not that we’re recommending that.

In fact, not only are we not recommending you fire the GR-1 Anvil in your basement, we’d recommend against it, since it frankly scares us. Why does it scare us? Well, because of this little tidbit on their website: “Full liability waiver must be signed by end user prior to shipment.” That reads “experimental” to us,it certainly looks experimental, and we sure never had to do that when buying a traditional firearm.

Anyway, if you’re willing to take your life in your hands, we’re guessing the GR-1 Gauss Rifle’s a lot of fun to fire. Unfortunately the video we watched on it didn’t show the makers actually firing it at the range, as we were hoping it would. See it here:

But, we did see an earlier developmental coil/Gauss pistol being fired in their shop here:

Oh, and in case you’d like to try their full-auto product, the EMG-01B, they’ve got a page and video on that one too, here.

And, here’s the video by itself:

The following information on the Arcflash GR-1 “Anvil” Gauss Rifle comes from the company’s website:

The Arcflash Labs GR-1 “Anvil” is an 8-stage semi-automatic high voltage Gauss Rifle. It is the most powerful coilgun ever sold to the public, and also (very likely) the most powerful handheld coilgun ever built.

The GR-1 is capable of accelerating any ferromagnetic projectile (under 1/2″ in diameter) to 200+ fps, and can deliver up to 75 ft-lbs of muzzle energy.

The GR-1 uses the world’s most advanced capacitor charging system, a dual Clamped Quasi-Resonant Inverter, which allows the GR-1 to fire up to 20 rounds per minute (at full power) or up to 100 rounds per minute at 50% power.

The GR-1 is capable of accepting 3 different standard projectile lengths (32 mm, 42 mm, and 52 mm) with a unique variable magazine system.

Arcflash Labs recommends the use of 1232, 1242E, or 1252 armatures, but any steel rod, fastener or dowel pin between [11-12.6mm in diameter] and between [30-52mm in length] should work. Please use caution when firing non-OEM armatures and refer to the user manual for guidance before firing. Arcflash Labs is NOT RESPONSIBLE for damage to the unit or personal injury caused by firing non-OEM armatures.
