Reptilla LLC 100027 Dot Mount Lower 1/3 Co-Witness for Aimpoint Acro - Flat Dark Earth Anodized

The Reptilia DOT Mount Lower 1/3 Co-Witness for Aimpoint Acro is a versatile adapter that extends the reach of your Acro red-dot sight far beyond the pistol slide. If you've standardized on the Aimpoint Acro for concealed carry or duty use, this mount transforms it into a capable AR-15 optic, placing it in the traditional lower-third sight line where it co-witnesses perfectly with your folding backup iron sights. That means your existing Acro becomes a dual-duty optic without the hassle of mounting-system switching.

Built from 7075-T6 aluminum with hard-coat anodizing in Flat Dark Earth, this mount is engineered to last. The spring-loaded clamp grips any standard Picatinny rail securely, and because the clamp bolt sits flush with the body, there are no snags waiting to catch on gear, slings, or terrain. Manufacturing is US-based, which means you're supporting domestic production and getting the attention to detail that comes with it.

If you run your Acro on a pistol platform and want the flexibility to bolt it onto an AR without buying another optic, or if you're building a hybrid rifle setup that plays well with irons, this lower-third mount delivers a straightforward solution.
