This X5L-RS Gen 3 is fantastic on my shotgun. The green laser is incredibly bright and easy to pick up, even in decent ambient light. It holds zero perfectly, which is key. The 500-lumen light floods an area nicely without being too concentrated. Viridian makes quality stuff, and this light/laser combo is no exception. Very impressed with the performance on a build that sees a lot of use.
Got the Viridian X5L-RS Gen 3 for my 5.56 carbine and it's been a game changer. The 500 lumens really cut through the dark, way better than some cheaper lights I've tried. Green laser is super crisp for quick target acquisition, especially useful for drills. Rail mount was easy enough. Definitely a solid light/laser combo.
