The JRC Rail Model in .45 ACP (brand part no. JRC45G3-TB/BL) is a semi-automatic pistol-caliber carbine operating on simple, reliable straight blowback, pairing a lightweight 17-inch threaded barrel with a fully ambidextrous bolt that can be configured for left- or right-hand ejection. BLS Supply machines the receiver, trigger housing, and magazine well from aerospace-grade 6061-T6 aluminum with black hardcoat anodizing, mounts a free-floating 13-inch M-LOK rail with a top Picatinny section, and fits a telescoping 6-position M4-style buttstock with standard M4/AR-15 furniture. The carbine feeds from an included 13-round Glock-pattern magazine and can convert to other pistol calibers with a separately sold conversion kit. Made in the USA in New York State. Among AR-platform rifles in the AR rifles category, the JRC Rail Model favors shooters who want a lightweight, ambidextrous .45 ACP carbine that shares Glock magazines.
