The Midwest Industries MK2 Railed Cap, 34mm (Midwest Industries part no. MIMK234RCAP) replaces a standard MK2 mount top cap with a short accessory rail, giving shooters a spot for a backup sight or secondary optic in case the primary scope fails. It is compatible with both the current and previous generation of Midwest Industries scope mounts, and is available in a variety of footprint patterns including RMR, Acro, T2, and Micro dot clones so it can host whatever red dot you already own. Precision machining keeps the cap true to the mount’s return-to-zero performance, and the top surface carries premium engraving of the mount’s torque specs for quick reference in the field.

Frequently Asked Questions

Will a tall-turret red dot work with this cap? Some red dots with taller turrets can have limited visibility once mounted on the cap, so check your optic’s turret height before ordering.

Why would I want a backup sight here instead of just the scope? A railed cap gives you a fast secondary aiming option directly in line with your primary scope in case the main optic ever fails in the field.
