The Armaspec Fulcrum45 Ambidextrous Safety Selector is designed for the AR15/AR10 platform, allowing for a 45-degree throw that facilitates faster disengagement compared to traditional 90-degree selectors. Its intuitive design features easy-to-reach levers and an incredibly smooth action, providing a natural and fluid movement for operators. With a super crisp lockup, users can confidently confirm their safety status. Ideal for various shooting scenarios, this ambidextrous selector operates seamlessly from both sides of the receiver. Note that it is compatible with receivers marked for a 45-degree fire position. For receivers without the correct markings, the 90-degree side should be used. Made in the U.S.A. from durable aluminum, the Fulcrum45 enhances operational efficiency and reliability in the field.
