The Strike Industries Sidewinder Sidewinder BUIS Black Folding For AR-15 is a dedicated backup iron sight set engineered for shooters who run full-size optics but still want immediate access to precise mechanical sights. Built around the low profile SI-Ambush mounting system, the Sidewinder rides close to the rail while its offset design lets you roll the rifle slightly to pick up a clean sight picture without disturbing your primary optic.

This model is purpose-built for AR-15 platforms that use MIL-STD-1913 Picatinny dimensions, giving you a consistent, repeatable zero on a wide range of uppers. The combination of steel and aircraft-grade aluminum keeps weight manageable while maintaining durability for hard range use and training. Whether you are refining fundamentals on the range or setting up a dependable rifle for general use, the Sidewinder reflects Strike’s focus on practical innovation and thoughtful design.
