The Timney 49er Ambidextrous Safety Selector (brand part no. AR 49ER-Safety) is a true drop-in safety selector for any Mil-Spec AR-15 lower receiver. It works as either a standard 90-degree safety or, with a quick adjustment, a 49-degree short-throw safety for faster manipulation under recoil. The ambidextrous arm can be removed if a shooter prefers a one-sided safety instead, and the selector itself is precision machined from heat-treated steel with a carbo-nitride coated safety plunger and a replacement spring for ultra-smooth operation with a positive, tactile engagement every time it is switched.
