The Kel-Tec SUB2000 Gen3 in 5.7x28mm delivers the high-velocity performance of FN's specialized cartridge in a compact, foldable platform. This tan polymer carbine transforms from a 30-inch rifle to a 16-inch folded package, making it ideal for vehicle storage and discreet transport.
What Makes This Different
Unlike traditional pistol caliber carbines, the SUB2000 Gen3 chambers the armor-penetrating 5.7x28mm cartridge, achieving muzzle velocities exceeding 2,000 fps from the 16.15-inch barrel. The patented folding mechanism allows the rifle to fold in half without removing optics or accessories, while the Gen3 improvements include enhanced ergonomics and improved reliability over previous generations. The lightweight polymer construction keeps the total weight under 4.5 pounds while maintaining structural integrity for rapid deployment.
Key Features
- 5.7x28mm chambering provides superior ballistics and penetration compared to 9mm alternatives
- Patented fold-in-half design reduces overall length from 30 inches to 16 inches when folded
- 20-round magazine capacity with compatibility for FN Five-seveN pistol magazines
- 16.15-inch threaded barrel (1/2x28 TPI) ready for suppressor attachment
- Picatinny rail system accommodates optics and tactical accessories
- Tan polymer stock and receiver resist corrosion and reduce weight
- Cross-bolt safety and magazine disconnect enhance operational safety
The 5.7x28mm cartridge's flat trajectory and minimal recoil make this carbine effective for precision shooting at extended ranges while maintaining rapid follow-up shot capability. The high-velocity projectiles retain energy downrange better than conventional pistol cartridges, making it suitable for varmint control and specialized tactical applications. The polymer construction and stainless steel barrel provide reliable function in adverse weather conditions.
