The Flipper is a unique vise block that will hold your AR-15 upper or lower receiver in place for repairs, installations and upgrades. One side will insert into the magazine well of your AR lower and provide a secure mounting point for a bench vise. Flip the block over, and it will insert just as easily into your upper receiver. Constructed of durable Delrin that will not scratch or damage your rifle.
Not recommended for high-torque applications such as barrel installation
