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 (dependent on ammunition).

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.
