UTG® AR15 Spring-Loaded Flip-up Rear Sight - ACCU-SYNC®, Black

Usually ships the same day or the next business day!

The ACCU-SYNC® AR15 Rear Sight by UTG® is designed from machined aircraft aluminum with a matte black finish. A posi-lock push button activates the spring loaded rear sight into position and prevents the sight tower from collapsing when deployed. No tools are needed to adjust the sight itself. For mounting onto your rifle's rail, all that's required is the single locking torx screw in its low-profile mounting base. It also has an integral recoil stop for a secure zero hold and return to zero.
