Perfect !!

This light is amazing ! I put it on my Daniel Defense 5.56 and it works great. I have seen several lights like this but none compare to the brightness and distance this one has. I would absolutely advise buying one of these while there in stock.

Should be able to see from space


Always went with SureFire. I decided to give Streamlight a chance at half the price and glad I did. The 10tap feature is great. Right now if I tap once 400 lumens, tap twice 1000 lumens, and press the clicking it on permanently gives me 1000 lumens. It does have a strobe function which I don’t use. The holes line up to most SureFire accessories. It’s mounted to an Arisaka offset mlok mount rather than adding a section of picatinny and using the included 1913 mount. It’s nice to be able to project 400lumens to conserve battery life because this will chew through em. Would I take it into a life or death situation probably not, I’d stick with SureFire. For my needs it’s perfect. Crazy bright and built like a tank. I d definitely buy again and recommend.

Favorite light, Streamlight is amazing.

Amazing light, especially for the money.
<br>Streamlight is my all time favorite manufacturer of weapon lights. As much as I'd love to buy Surefire lights, you can purchase three Streamlights for the price of a single Surefire.
<br>- Durable
<br>- Included tape switch
<br>- Bright
<br>- Cost effective

Great light even better price.

This light is incredible, I needed a light for predators around the house, this light goes the distance! I can light up any corner of my property brightly with this setup! And as always Primary Arms is so fast and dependable, you can't ask for better!



As a LEO, I've been using Streamlight for years because it's what my department issues standard for pistol lights (TLR-1). I picked up one of these for one of my rifles in an attempt to save $$$ over the Surefire Scout. I liked the light so much I bought a second one for another rifle. These lights are ridiculously bright. And the built on rail mount makes placement and install easy. If these hold up as well as my TLR-1s have, then these lights are the best possible value you can get.

Light em up!

Just ordered my third one for a new ar15 pistol build. Have one on another pistol also on my sbr. Really throws the overall light out with a excellent hot spot.
