XS R3D 2.0 Night Sights for Glock Pistols with A-CUT

XS Sights has released its R3D 2.0 night sights, available with either green or orange dual-illuminated front sights, for Glock pistols equipped with the A-CUT optics cut. These A-CUT models allow direct mounting of the new Aimpoint COA red dot optic, and the low-profile design of the R3D 2.0 keeps the sights sitting in the lower fifth of the optic’s window. This placement minimizes visual obstruction and makes the sights a practical backup option should the optic fail.

• New Aimpoint COA Red Dot - In Collaboration With Glock
• [SHOT 2025] Aimpoint COA Red Dot Sight and A-CUT

I tried the Aimpoint COA with the new Aimpoint A-CUT system late last year, and I think it’s a really clever attachment system. There were (and continue to be) a lot of misconceptions that you couldn’t change to other iron sights, which was, of course, wrong, as proved by this product here from XS Sights.

The R3D 2.0 sights are designed for straightforward, do-it-yourself installation using basic hand tools. XS has also made several dimensional refinements to improve usability and overall fit for Glock owners.

“We designed this R3D 2.0 rear to be slightly longer than the factory sight to minimize the area between the iron sight and optic lens – a space which tends to collect dirt and debris,” said Jeff King, Marketing Manager, XS Sights. “We also made the sides of our rear sight flush with the Glock slide to reduce snag potential while providing a cleaner, more streamlined look.”

Product Features:

• Tritium front and rear with high contrast glow dot
• Photoluminescent glow dot absorbs ambient light and glows in low light
• Wide notch rear with serrations and anti-reflective lens
• Corrosion resistant Black Nitride surface finish
• Traditional 3-dot tritium, notch and post, sight picture
• Compatible with Glocks Gen 1-5, including MOS models
• Proudly manufactured in Fort Worth, TX

According to the news release, the retail price is $137.99; however, they are listed at $124.99 on XS Sights’ website.

XS sights are backed by a Limited Lifetime Warranty, and they also offer a 12-year illumination warranty on all tritium products. For more information, visit https://xssights.com/products/r3d-2-0-night-sights-fits-glock.html
