The SUB-2000 Gen 1 folds at the barrel/receiver hinge for compact storage, delivering a handy 9mm carbine that stows easily. It uses a simple blowback action with a cross-bolt safety and an under-tube charging handle for straightforward operation. The polymer skeletonized buttstock provides a 13.5 in length of pull and integrates a pistol grip.
Red Lion Precision upgrades distinguish this example. The R6B rotating quad-rail forend adds robust aluminum rails and a knurled index/lock collar for repeatable positioning, with polymer ladder covers installed. The R7B clamp-on front sight features click-adjustable windage and elevation drums, giving precise mechanical adjustments at the front sight position.
