Area 419 Rmr Mount For Tactical One-Piece
The Area 419 RMR Mount for Tactical One-Piece gives you a rock-solid way to run a secondary optic or mounted accessory on top of your rifle scope. Built for the Area 419 Tactical One-Piece mount, this aluminum accessory uses a patent-pending dual-taper attachment that locks onto the scope cap with confidence—ideal for hunters and shooters who want to add a close-range red dot, laser rangefinder, or level to their long-range setup without compromising zero.
Machined from 7075 American aluminum and Type III hard-anodized black, this mount delivers the rigidity you need for repeatable returns to zero. Captive mounting screws keep hardware from getting lost in the field, and the whole assembly weighs just 1.5 ounces. At 0.875 inches tall and 1.69 inches from the tube to the RMR footprint, it's compact enough not to crowd your optic but tall enough to clear most scope turrets.
Whether you're stacking a Trijicon RMR, Holosun 507C/508T, Swampfox Liberty, or any other RMR-footprint optic, this mount plays well with the full ecosystem of modern compact red dots and accessories. It's the kind of accessory that separates a dialed rifle from a half-finished one—small in weight, big in capability.
