The RS Regulate Modular Upper is designed for Trijicon MRO pattern optics and features a matte black finish.
In 2012, RS Regulate began rolling out the first models of the AK-300 Modular Side Mount System, which now features six fully modular uppers and nine different lowers.
Those lowers include options for a front-biased, a rear-biased, and a full-length lower for most Eastern European AK side rails; a front-biased and full-length lower for Yugo/Serbian rifles; a PSL and Romanian M10/RH10 rifles; a Century Arms proprietary side rail; and a rear-biased lower for Czech vz. 58s.
