The Strike Industries SIDEWINDER black folding BUIS for AR-15 is a low-profile backup iron sight built for shooters who want a reliable secondary sighting system without adding bulk to the rail. Whether you're running a primary optic on your patrol rifle, competition build, or duty carbine, a quality folding rear sight keeps you in the fight if your glass goes down. Strike Industries' SIDEWINDER delivers that redundancy in a compact package designed to co-witness or lower-1/3 co-witness with standard AR optics.

Folding sights earned their reputation by staying out of the way until you need them. The SIDEWINDER folds flat when not in use, clearing your line of sight and protecting the sight posts from snags and impacts. When deployed, it's rigid enough to hold zero through repeated shooting sessions—something you can't say about low-rent stamped alternatives. Black anodized finish resists corrosion and glare, fitting seamlessly into modern AR builds whether you're running a night-vision setup, magnified optic, or reflex sight up front.

Strike Industries has built a following among tactical shooters, competitive riflers, and hunters who refuse to compromise on backup systems. The SIDEWINDER sits in that sweet spot: solid engineering at a price that doesn't require choosing between sights and ammo. Pair it with a front folding sight to complete your redundant setup, or use it solo as insurance behind an ACOG, Nightforce scope, or red dot.
