Frequently Asked Questions
Does the Sub-2000 Gen 3 accept optics or accessories?
The Gen 3 Sub-2000 was redesigned to allow the rifle to be opened and closed without removing a mounted optic — a significant improvement over earlier generations. It is compatible with a variety of red dot sights and features an M-LOK compatible forend for attaching lights, grips, and other accessories. Since no sights are included, adding a quality red dot or reflex sight is recommended for most users.
What makes the 5.7x28mm cartridge a good choice for a folding carbine?
The 5.7x28mm is a bottlenecked, high-velocity cartridge originally developed for personal defense applications. It produces minimal felt recoil, making it easy to stay on target during rapid fire. When fired from the Sub-2000's 16.25-inch barrel, the cartridge achieves higher muzzle velocities than from a pistol, delivering improved ballistic performance. The round is also relatively lightweight, allowing shooters to carry more ammunition without adding significant weight.
Is the Sub-2000 Gen 3 legal to purchase in California?
Firearm laws in California are complex and subject to change. The Sub-2000's folding stock and magazine capacity may be subject to specific state regulations, including California's assault weapon laws and magazine capacity restrictions. We strongly encourage customers to consult with our store team at Goodland Guns or a qualified legal professional to confirm compliance before purchasing. Our staff is experienced in helping California residents navigate these requirements.
