Manufactured in Canandaigua, New York, Just Right Carbines are designed to be a simpler, more reliable, and more flexible carbine in centerfire pistol calibers. The JR Carbine is an ambidextrous, straight blowback-operated, semi-automatic rifle on an AR-like platform. The JRC's receiver, trigger housing, and magazine well are machined from aerospace grade 6061 T-6 aluminum with black hardcoat anodizing for extra protection and durability. These rifles are ambidextrous and accept Glock or 1911 magazines (depending on the model) as well as all standard AR-15 accessories. Every Just Right Carbine comes standard with a mil-spec Picatinny rail. Other features include: a telescoping 6-position collapsible M-4 style buttstock, a free-floating quadrail forend, and a standard M4 buffer tube, buttstock, and pistol grip. The 9mm JRC has a threaded barrel and comes with a 17-round magazine.
