The '''Arcflash Labs GR-1 "Anvil"''' is a portable shoulder-fired semi-automatic bullpup 8-stage coilgun designed and manufactured by Arcflash Labs in Los Angeles, California.<ref name=":0">{{Cite web|title=Arcflash Labs|url=https://arcflashlabs.com/|access-date=2022-02-11|language=en-US}}</ref><ref name=":1">{{Cite web|last=McCollum|first=Ian|date=2022-02-11|title=ArcFlash Labs' GR-1 Anvil Portable Gauss Rifle|url=https://www.forgottenweapons.com/arcflash-labs-gr-1-anvil-portable-gauss-rifle/|access-date=2022-02-11|website=Forgotten Weapons|language=en-US}}</ref> It is the most powerful handheld coilgun ever sold publicly.

== Operating mechanism == The GR-1 uses a clamped quasi-resonant (CQR) step-up inverter described in [https://patents.google.com/patent/US10811995B2 U.S. Patent 10,811,995],<ref name=":0" /> which allows a six-cell 25.2 volt lithium-ion polymer battery to supply up to 1000 watts of power to eight high-voltage electrolytic capacitors in approximately three seconds.<ref name=":1" /> As with most coilguns, the eight aforementioned capacitors are used to power eight respective electromagnetic coils in the configuration of a linear motor to accelerate a ferromagnetic or conducting projectile to high velocity.

Although the "GR" designation purports the device to be a "Gauss Rifle", as evidenced both by the company<ref name=":0" /> and media reports,<ref name=":1" /><ref name=":2" /> this is technically a misnomer on two counts—it is neither a rifle (as it doesn't use rifling) nor a Gauss gun (a type of accelerator that uses permanent magnets and is distinct from a coilgun).

== Legality ==

Under United States law, "firearms" are defined as propelling a projectile by combustion. Coilguns such as the GR-1 do not have any combustion mechanism, and therefore are not legally considered firearms. However, Arcflash Labs legally refers to the GR-1 as an air gun out of an abundance of caution.<ref name=":1" />
