Troy Industries AR-15 FIXED TACTICAL BATTLE REAR SIGHT BLACK SSIG-FRS-R0BT-00

Tactical backup sight is always deployed, so there’s absolutely no delay, no fumbling when you need to transition from the primary optic. Troy designed this sight to be simple, rugged, and reliable—and it takes up only 1-1⁄8" of rail space. Precision machined from solid aluminum, with plenty of metal on the protective “ears” around the two-position aperture. All edges and corners are rounded, and there are no protruding knobs or levers to catch on brush, clothing, or other equipment. Rear of the base is undercut to provide clearance for access to the charging handle. Same-plane aperture flips easily between .190" and .070" diameter peeps, just like the Folding Rear Battle Sight. Windage adjustable in ½ MOA clicks using a coin in the slot of the flush A1-style detent-locking adjustment wheel. Clamps to any Picatinny rail; installs with a standard flathead screwdriver.
