RS Regulate Modular Upper for Trijicon RMR

RS Regulate AK-300 Modular Upper System

RS Regulate's modular upper system represents a thoughtful engineering solution for shooters who demand flexibility in their AK-pattern rifle setups. This upper component is designed to work seamlessly with popular compact red dot sights, including the Trijicon RMR and Holosun HS507C.

Modular Design Philosophy

The AK-300 system features a fully modular architecture that allows you to configure your rifle for your specific needs:

• Six different upper configurations to match your sight choice and mounting preference
• Nine lower options covering most AK variants and platforms
• Front-biased, rear-biased, and full-length lowers for Eastern European AK side rails
• Specialized lowers for Yugo/Serbian, Romanian, and Czech vz. 58 rifles
• Century Arms compatibility for proprietary side rail systems

Practical Advantages

This modular approach means you're not locked into a single configuration. Whether you're building a dedicated precision rifle, a tactical platform, or a general-purpose AK, RS Regulate's system adapts to your vision rather than forcing compromise.

The matte black finish provides a professional appearance while resisting glare and reflection. The engineering reflects RS Regulate's commitment to creating solutions that work across the diverse world of AK-pattern rifles.
