Key features breakdown

MIL-STD Receivers

MIL-STD upper and lower receivers mean a robust interface and parts compatibility with a wide range of AR components. That ensures easier future upgrades and reliable indexing under sustained use.

7″ RPR Free-Float Rail

The 7″ RPR free-float rail isolates the barrel from handguard pressures for tighter groupings and better heat dissipation. The rail’s length keeps your forward hand off the hot barrel and offers plenty of room for weapon lights, laser aiming devices, and quick-detach accessories.

SB-Tactical SBA3 Brace

The included SBA3 5-position adjustable brace enhances cheek weld and control on a compact platform. It’s a practical addition for shooters who need quick, repeatable transitions without adding significant length.

Handling and applications

The RF-15’s 5.56mm chambering remains a versatile choice for training and defensive roles—light recoil, common ammunition, and effective terminal performance within typical engagement ranges for a compact pistol. The short M4 profile barrel and free-float rail make the platform ideal for close-quarters use, vehicle carry, and as a lightweight backup system for patrol or range applications.
