The KelTec Sub2000 Gen 3 10mm Green (KelTec part no. SUB2K10GLKGRN) is the third generation of the maker’s semi-automatic carbine that folds in half. A rotating forend makes it optics ready, so a red dot can stay mounted and zeroed while the rifle folds, which earlier generations could not do. The 10mm chambering and 16.1-inch barrel give a pistol cartridge more reach than a handgun can, and the rifle takes Glock 20 magazines. Folded, it tucks into a pack or a vehicle for camp, trail or range use.

Key Specifications

• Barrel length is 16.1 inches, which KelTec says turns into more velocity and power downrange.
• Magazine capacity is 15 rounds on this green model.
• Magazine fit is Glock 20, so this 10mm model can share magazines with a Glock pistol.
