Kel-Tec R50 5.7x28mm Carbine 50+1 Green 16.1" Threaded Barrel

The Kel-Tec R50 delivers exceptional firepower in the versatile 5.7x28mm cartridge, combining a massive 50-round magazine capacity with the precision of a 16.1-inch threaded barrel. This carbine addresses the demand for high-capacity, low-recoil performance in a compact package. Built with Kel-Tec's signature green polymer receiver and folding stock design, the R50 maximizes portability without sacrificing capability.

What Makes This Different

While most carbines in this class offer 30-round capacity, the R50's proprietary 50-round magazine system provides 67% more ammunition on tap. The 5.7x28mm cartridge generates significantly less felt recoil than traditional rifle rounds while maintaining flat trajectory and barrier penetration capabilities. The side-folding stock reduces overall length to just 26 inches when folded, making it exceptionally maneuverable in tight spaces. The threaded muzzle accepts standard 1/2x28 accessories including suppressors and muzzle devices.

Key Features

• 50+1 round capacity with proprietary magazine system
• 16.1-inch cold hammer forged barrel with 1/2x28 threading
• Side-folding polymer stock for compact storage and transport
• Adjustable front and rear sights with standard sight radius
• Quick-detach sling mount points for tactical carry options
• Green polymer receiver with integrated Picatinny rail sections
• Ambidextrous safety and magazine release controls

The 5.7x28mm cartridge's high velocity and low mass deliver exceptional accuracy at extended ranges while minimizing shooter fatigue during extended sessions. Law enforcement agencies appreciate the round's barrier penetration characteristics and reduced overpenetration risk in urban environments. Competition shooters benefit from the minimal recoil impulse and rapid follow-up shot capability. The threaded barrel accommodates sound suppressors for tactical applications or hearing protection.
