Modern semi-auto carbines that balance capacity, compact handling, and accessory options are in demand for range use, home defense, and patrol roles. Riders of this category need a platform that accepts optics, maintains controllable recoil, and offers practical mounting space without adding unnecessary weight.

KELTEC R50 GREEN delivers a clear mission profile: high-capacity rifle ergonomics in a compact carbine package.

Key features and field utility

The R50 stands for Rifle – 50 Rounds, a direct nod to its high-capacity intent contrasted with the P50 pistol variant. This carbine sports a side-folding stock that rests comfortably on either side of the grip when folded, making it compact for storage or transport while retaining a full-length platform when extended. The 1/2 x 28 threaded, 16-inch barrel lets you fit muzzle devices or suppressors where local law permits and preserves effective ballistic performance for typical defensive and range loads.

Optics and accessory mounting

The receiver provides over 7 inches of Picatinny rail on top — more than enough real estate for red dots, magnified optics, or a combination of sights. Two inches of rail on the bottom accommodate lights, vertical grips, or training accessories. Utility sights are included and adjustable for windage and elevation, but the upper rail makes it simple to upgrade to a dedicated optic without clearance headaches.

Ergonomics and controls

Functionally, the R50 places a QD sling cup just above the magazine release for single-point sling attachment, keeping load-bearing hardware close to the weapon’s balance point. The AR-style charging handle provides smooth, familiar manipulation for shooters accustomed to modern sporting rifles. Note that caliber is not specified in the product details shown here — verify chambering on the product page before buying to ensure compatibility with your intended use and ammunition supply.

At a street price of $734.99, the R50 offers a unique combination of magazine capacity and compact handling compared to other semi-auto carbines in this segment. View product details and pricing to confirm current stock and shipping options.
