Armaspec Fulcrum45 Features The Armaspec Fulcrum45 is engineered with a 45 degree throw rather than the traditional 90 degree sweep allowing the shooter s thumb to disengage the safety more quickly under pressure. Its ambidextrous design lets the selector be operated easily from either side of the receiver supporting shooters regardless of handedness or shooting position. Easy to reach levers combine with an incredibly smooth action making position selection feel like a natural fluid movement during a string of fire. The super crisp lockup gives the shooter clear tactile and visual confirmation of the rifle s safety status at a glance. Machined from aluminum and manufactured in the United States the Fulcrum45 is built for long term durability under repeated use. The 45 degree side is intended for firearms with the correct FIRE markings on the receiver that match the 45 degree fire position so shooters should confirm their lower s markings before installation. If a receiver lacks the correct 45 degree markings the 90 degree side of the selector should be used instead. For AR-15 and AR-10 owners looking to speed up their safety manipulation the Armaspec Fulcrum45 is available for sale at GrabAGun.
