Kel-Tec R50 Folding Stock 5.7x28mm FN Black Rifle

The Kel-Tec R50 is a semi-automatic 5.7x28mm FN rifle built around the high-capacity P50 magazine system. Its 16.1-inch threaded barrel and side-folding stock provide a practical carbine configuration, while the folded stock rests alongside the grip for compact storage. Adjustable utility sights support immediate use, and more than 7 inches of Picatinny rail on top of the receiver provides ample space for a red dot, scope, or other compatible optic. A lower accessory rail supports lights and foregrips, while the AR-style charging handle and QD sling cup contribute to convenient handling and carry.
