Questions & Answers
I have a Military Armament Corp MAC5, will the XS sight fit this model? Manufacturer Answer

We have not tried them on the MAC 5. The sight is a direct replacement for the front sight blade on an HK or a PTR clone. If the MAC 5 is using sights compatible with an HK MP5, then it will work.

What is the width distance between the stock sight and the tritium. Asking because the one I put on my AR platform cant shoot distance now Manufacturer Answer

This front sight is wider than the factory front sight. It is .140" wide.

Product Info for XS Sight Systems HK 91, 93, 94, MP5, SK5 Standard Dot Tritium Night Sight

Standard Dot front sights use a patent pending glow dot that absorbs light and glows in low light levels before it is dark enough to see the tritium.Green is a great option for low light and has a very bright glow intensity. The surface area of the convex dot increases light absorption, intensifying the charge of the glow properties of the dot.image
