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.



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.

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!

Great light even better price.

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

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.

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.
