Description: GG&G A2 Back Up Iron Sight With Locking Detent, Rear. The GG&G A2 AR-15 Back-Up Sight (BUIS) provides the operator with an easy-to-install and easy-to-operate flip-up rear sight and includes the all-important locking detent. Besides providing a low profile "ready to go" BUIS when you need it, its features include a tactile ergonomic windage knob and counter sunk crossbolt to eliminate the possibility of snags, incorporated in a streamlined body.
