The KelTec R50 is a semi-automatic rifle chambered in 5.7x28mm FN and designed around the same high-capacity magazine system as the P50 pistol. Its 16-inch threaded barrel and side-folding stock provide a compact, adaptable configuration, with an overall length of 30.5 inches. Adjustable sights support practical aiming, while more than 7 inches of top Picatinny rail and 2 inches of lower rail provide ample space for an optic, light, or grip. An AR-style charging handle and QD sling cup add convenient handling and carry options.
