The Sidewinder 2 represents the next evolution of Strike Industries’ highly successful Sidewinder backup iron sights. After gathering feedback from competition shooters and military personnel in the field, these sights have been upgraded to easily handle not only 5.56 but also larger calibers and harsher environments. Maintaining their original design concept, the Sidewinders provide a quick-access option for 45-degree offset or traditional inline capabilities-all in one package. Tool-less adjustment dials enable easy sight adjustments. Whether you need a low-profile, low-snag inline backup for your red dot or a short-range, offset CQB sight backup for magnified optics, the Sidewinder can meet your needs. The low-profile SI-Ambush mounting system can clear even the largest optics, and the offset sight allows instant access to your backup iron sights without removing your optic.
