SKU: 419-ALK-MLOK12
Overview
Built for precision rifle setups, this rail gives hunters and shooters a stable attachment point along the stock forend while remaining compatible with standard Arca accessories. Its serrated dovetail design is intended to work with Area 419’s clamp system for a more secure lockup, and the underside M-LOK slots add room for mounting compatible accessories. The 12-inch length provides substantial mounting space, but it does require 6 consecutive M-LOK slots to install, so it is best suited to stocks with enough uninterrupted slot coverage. Finished with a hard coat anodize and supplied with M-LOK mounting hardware, it is a purpose-driven option for rifles that need a clean, modular support interface.

Considerations & Trade-offs
- Requires 6 consecutive M-LOK slots to attach, so it may not fit stocks with shorter or interrupted slot spacing.
- The locking function depends on an Area 419 clamp; with standard Arca accessories it remains compatible, but not locking.
- At 12 inches long, it provides substantial attachment space, but that length may be more rail than some setups need.
- M-LOK mounting hardware is included, but the rail is still a dedicated add-on that needs to match the stock’s existing layout.
