Also known as: JR Carbine, JRC Gen 3
Overview
The Just Right Carbines JRC is an American 9x19mm pistol-caliber carbine built on a one-piece machined 6061-T6 aluminum receiver with AR-15-pattern fire controls and ergonomics. It feeds from standard Glock magazines (with .40 S&W, .357 SIG and .45 ACP options on other models), features a fully reversible ejection port and ambidextrous controls, and breaks down tool-free into three parts for compact storage. Introduced around 2010 by Just Right Carbines of Canandaigua, New York, it remains in production in its Gen 3 form.

Background
The JRC's signature trick is a tool-free takedown that breaks a full-size 17-inch carbine into three pieces in seconds, letting it stow in a small carry bag, and it shares both magazines and ammunition with a Glock sidearm so rifle and pistol feed from the same supply.
