The Odin Works Ambidextrous Modular Safety (AMS) for AR-15 and AR-9 rifles makes quickly changing from safe to fire extremely easy. The enlarged paddles allow you to easily find them when under the stress of the clock in 3 gun or similar competitions and are designed to give you better control through a more ergonomic angle. This safety selector is highly configurable and can be set to 8 different orientations depending on your preference. The selector barrel also allows it to be set at the 90 or 45-degree angle for a fast and smooth throw. It also features an ambi safety design so it can be used by either left or right-handed shooters.
