Frequently Asked Questions
Are the Strike Industries Sidewinder BUIS II sights compatible with my red dot or magnified optic?
Yes. The Sidewinder BUIS II is designed with a low-profile folded position that clears most red dot sights and magnified optics without obstruction. When deployed, they can be used in an absolute or lower-third co-witness configuration depending on your optic's mount height. Always verify co-witness compatibility with your specific optic before purchasing.
Do I need any tools to install or zero the Sidewinder BUIS II?
Installation requires a standard Picatinny rail and typically a small hex key or tool-free lever depending on the clamp design. Windage and elevation adjustments can be made with a cartridge tip or coin in the field, making it easy to zero without a dedicated toolkit. Refer to the included instructions for exact zeroing procedures.
Is the Sidewinder BUIS II sold as a set (front and rear), or individually?
The Strike Industries Sidewinder BUIS II is typically sold as a set including both a front and rear flip-up sight, giving you a complete backup iron sight solution right out of the box. Confirm the package contents at checkout or contact Goodland Guns to ensure you're getting the full set for your build.
