Strike Industries SIDEWINDERIIBK Sidewinder II Black Back Up 45 Degree Offset

The Sidewinder 2 is the next evolution of our Sidewinder backup iron sights. After receiving feedback from competition shooters and military personnel in the field the sights have been upgraded to easily handle not only 5.56 but larger calibers as well as harsher environments. Keeping our same design concept the Sidewinders offer the on the go option for 45 degree offset or traditional in line capabilities all in one package. Toolless adjustment dials allow 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 fill your needs. The lowprofile SIAmbush mounting system can clear even the largest of optics and the offset sight means instant access to your back up iron sights without removing your optic.
