JP Adjustable/Reversable SelectorJP adjustable safety, reversible, including low-profile ambi lever for AR-15 receiver. Can be used to eliminate the safety fitting process for the JPFC kits and provide perfect safety fit for many other aftermarket trigger systems.Notice: Replacing any original JP fire control components with non-JP aftermarket components may render the JP adjustable safety nonfunctional by allowing the rifle to fire on safe. For example, some two-stage triggers will not interface with the JP adjustable safety, which will not fully block the trigger in the safe position and allow the trigger to function even with the safety engaged. If you install a non-JP trigger system in the JP adjustable safety, it is imperative to verify its function.
