Design and Handling

The SUB2000 Gen3 features a collapsible design that halves the rifle’s length for storage and transport without sacrificing a usable stock when deployed. The 3-position stock gives adjustable length of pull to fit operators of different sizes or layered clothing. The Picatinny M-LOK combo handguard supports optics, lights, and foregrips while keeping weight low for easy maneuvering.

Gen3 Upgrades That Matter

Rotating Forend and Optics Compatibility

The most notable Gen3 addition is the rotating forend. This smart change lets you fold the carbine with optics mounted, eliminating the need to remove a red dot before stowage — a real convenience for quick deployment and storage in compact spaces.

Controls and Trigger

Ergonomics are improved with a redesigned charging handle and a lightened action that reduce fatigue in repetitive handling. An ambidextrous bolt hold open improves follow-up ergonomics for both hands, and the new aluminum trigger delivers a crisper pull for more consistent trigger control during rapid strings.

Caliber and Practical Applications

Chambered in 10mm Auto, this SUB2000 brings increased velocity and terminal performance compared with common pistol calibers, making it suitable for protection and heavy-hitting target work. The included one 15-round Glock-style G20 series magazine gives immediate interoperability with widely available magazines and parts for the G20 family.
