Kel-Tec SUB-2000 with Sig Sauer Romeo 5 Scope
semi-automatic carbine that folds in half, optics and all. Initially in 9mm, the SUB2000 GEN3 picks up where handguns leave off. Folded, it tucks away nicely in situations where space is limited, but it’s quick to deploy in situations where time is of the essence.
