Transfer Lever for HK MR & Sig Spear Heavy 277

MR556/MR762 and MCX Spear (277/308 Versions) Transfer Lever for ARC-Fire V2 This transfer lever is offered for customers using H&K MR556 and MR762 platforms as well as Sig MCX Spear 277 and Spear 308 platforms for optimized compatibility and reliability. The standard ARC lever works with MR platforms, this improves reliability and long-term function. This comes as a single lever and works with existing ARC-Fire V2 kits. This WILL NOT work with ARC-Fire V1 Kits. The Spear 277/308 platforms require the MCX trip kit in addition to this lever (alternatively, this is sold as a bundle with the Spear Heavy Kit HERE). DO NOT USE THIS WITH ANY OTHER PLATFORMS.
