FAQs

Can I apply the same sight to AK Pattern Firearms?

No, the sights designed for AR Pattern Firearms may not be directly compatible with AK Pattern Firearms due to differences in the sight base and mounting systems. However, at XS Sights, we offer similar sights specifically designed for AK Pattern Firearms that provide excellent functionality and durability.

Do I need to purchase an installation tool separately?

No, you don't need to purchase an installation tool separately. At XS Sights, we understand the importance of convenience for our customers. Our sights come equipped with an installation tool, making the installation process straightforward.

What sights should I choose for up close target acquisition?

If you're looking for sights that excel at up-close target acquisition, our 45° Offset Backup Iron Sights (BUIS) are an excellent choice. These sights are designed for shooting at pistol ranges and provide a rapid and reliable aiming solution when transitioning from a magnified optic or engaging close-range targets.

Which sight do you recommend for tactical use?

If we had to highlight one, we recommend our Big Dot and Standard Dot Tritium Fronts for tactical use. Our 45° Offset BUIS are another great option since they allow for quick sight transition from magnified sights.

What is the purpose of equipping backup iron sights (BUIS)?

Backup iron sights provide a fallback aiming solution in case the primary sight becomes non-functional due to damage, battery failure, or other issues. They are also useful for close-quarters situations. Our flip up AR sights are a great example of this; they are low and out of the way but can be deployed quickly when needed.

Do you offer colors other than white for the front stripe?

Currently, we only offer white for the front stripe. We find white to work the best since it will reflect more of the ambient light that hits than any other color.
