Just Right Carbines JRC Gen 3 Rifle | 9mm | 17in Threaded

The Just Right Carbines Gen 3 JRC M-Lok is a semi-automatic pistol-caliber carbine configured around AR-standard controls and ergonomics. It features a 17-inch threaded barrel, a 13-inch M-LOK-compatible handguard, and fully ambidextrous controls for flexible setup. Intended for range use and competition-style pistol-caliber carbine work, it accepts standard AR parts and converts to other pistol calibers with a conversion kit (sold separately). A compact 1x red-dot such as a Trijicon MRO or an Aimpoint PRO (both commonly available under $1,000) pairs well for close-to-midrange sighting on this platform.

The threaded 17-inch barrel accepts a variety of muzzle devices or suppressors where legal, and AR-standard parts reduce long-term maintenance friction. Its weight and adjustable stock provide a stable, controllable platform for sustained shooting sessions while remaining easy to handle.
