SUB2000™ GLK 10mm
The SUB2000™ GLK 10mm is a folding, semi-automatic carbine chambered in 10mm Auto and compatible with Glock® 20 magazines. The Gen 3 platform adds a rotating forend, allowing it to fold with optics mounted. It features a 16.15” barrel, blowback action, M-LOK® handguard, threaded barrel, and adjustable sights.

MSRP: $599 | Black finish

The SUB2000 GLK 10mm feeds reliably from Glock® 20 magazines, including extended stick mags and even a 50-round drum. This makes it a perfect pairing for Glock® 20 owners looking to share mags across platforms.
