Product Description
The RS Regulate AK-307MS Yugo Full-Length Lower is a precision-engineered lower optic mount designed for Yugo/Serbian pattern side rails found on Zastava PAP and M21 rifles. Part of the AK-300 Modular Side Mount System, this lower pairs with RS Regulate upper mounts to position your optic directly over the bore for ideal eye relief. Machined from durable 6061‑T6 aluminum with a matte black finish, it features RS Regulate’s unique titanium-based low-profile locking system for a secure, repeatable hold without interference to the trigger guard area. The AK-307MS requires an RS Regulate upper mount and is not compatible with AKM pattern rails, nor with M92 or M85 models that lack factory side rails.
