Introducing the Sidewinder 2, the evolution of our highly successful Sidewinder back-up iron sights, driven by valuable feedback from competition shooters and military personnel. These sights have undergone significant upgrades to handle not only 5.56x45mm Cal but also larger ones, while thriving in harsh environments. Maintaining our proven design concept, the Sidewinders offer the convenience of on-the-go options, allowing seamless transition between 45 degree offset or traditional in-line capabilities - all bundled into one package. With tool-less adjustment dials, sight adjustments are quick and effortless. Whether you require a low profile, snag-free inline backup for your red dot, or a short range, offset CQB sight backup for magnified optics, the versatile Sidewinder caters to all your needs. The SI-Ambush mounting system, designed to be low profile, easily accommodates even the largest optics. The offset sight design ensures instant access to your back-up iron sights without the need to remove your primary optic.
