Running an ARC-Fire V2 in an HK MR556, MR762, or SIG MCX Spear? This is the transfer lever built for those heavy platforms — M2 tool steel with a DLC finish, engineered for optimized compatibility and long-term reliability where the standard lever merely works.
What It Does
The standard ARC-Fire lever functions in MR-pattern rifles — this dedicated lever improves reliability and long-term function under the heavier operating systems of the MR556/MR762 and the Spear 277/308. It comes as a single lever and drops into your existing ARC-Fire V2 kit.
| Material | M2 tool steel, DLC finish |
| Fits | HK MR556, HK MR762, SIG MCX Spear .277 Fury, Spear .308 |
| Requires | ARC-Fire V2 kit (this replaces the standard lever) |
| Spear 277/308 also requires | The MCX Heavy trip kit — ask us about the bundle |
⚠ V2 only, these platforms only. Will NOT work with ARC-Fire V1 kits, and must not be used on any other platform — you risk damage to the lever, the host, or yourself.
Pairs your Spear or MR build into the AS Designs ecosystem — the widest platform support of any reset system we carry. See the full lineup on our AS Designs brand page.
