FCD Forward Controls Design ABC/R v4 Augmented Bolt Catch ABC/R v4 AA

The Forward Controls Design ABC/R v4 Augmented Bolt Catch is designed for TDP-spec AR15/M16 receivers in 5.56mm and features enlarged, angled upper and lower paddles for improved tactile access. Machined from billet 8620 alloy steel, heat treated, and finished with DLC, the ABC/R v4 provides increased lower-paddle surface area while separating the bolt catch from an ambidextrous magazine catch. The v4 is available with forward-biased (FB), standard, or rearward-biased (RB) upper paddle configurations to accommodate different reloading techniques. Proudly designed and manufactured in the USA, the ABC/R v4 is intended for 5.56mm AR15/M16 platforms and is not designed for 9mm PCCs or incompatible billet and fully ambidextrous receivers.
