The KelTec SUB2000 Gen3 is a lightweight, folding semi-automatic carbine known for its compact storage design and innovative construction. Chambered in the high-velocity 5.7x28mm cartridge, this Gen3 model combines the recognizable SUB2000 concept with KelTec's updated rotating forend system, allowing the firearm to fold while accommodating a mounted optic.

This used example offers a distinctive combination of portability, modern features, and the increasingly popular 5.7x28mm cartridge.
