AS Designs Transfer Lever | HK MR556 MR762 & SIG Spear 277/308 | ARC-Fire V2
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.
