Question: This light seems to be designed for use on pistols. How would it work on an AR 15 with a quad rail?
Document: This was purchased to put on my AR-15. Let me tell you that this is a quality light and it is super super bright! when properly mounted to the rail the on/off/strobe switch is very easy to access. I highly recommend Streamlight products.
Another great Streamlight product. I have it on the bottom rail of my AR. Easy to mount, durable and the light quality is excellent. Would strongly recommend.
The light is VERY powerful ! The strobe function is easy to use even without a remote switch just a simple double tab and hold also seams as if it was designed to be used with a magpul AFG grip (on AR platform) and kudos to ordered last night got it next day (sat.) early afternoon no extra charge!
These are awesome lights, super bright ,I returned this one because it did not work for the application in which I was going to use it but have a fewe of the Streamlights to review on..
I have seen this work at night by a friend of mine. It will do the job for me. Would recommend it.
Don't waste your time on the cheap ones from Big5, and don't waste your money on the expensive ones. This light is high quality, rugged, and is extremely effective and affordable. Place as far forward as possible to minimize shadowing, and you will be rewarded with the best and most affordable lighting solution for your AR-15 (or whatever gun you put it on).
the light itself is great but I think I would go with a standard TLR-1 on my next rifle. the flared out front piece makes it so you can only mount it at the very front of the rail which is difficult if you have a bayonet lug on your rifle.
Got it for 223 ar 15. The light shines easily 200 yards and is dead centered with my red dot. Will purchase nothing but this for my weapon systems.
This really is an awesome light, It works great and is blinding bright. The strobe feature really will mess with who ever vision it is pointed at. These lights are just as bright and work just as great as the Surefire's but at half the price.
This is a great light for mounting on a rail, but be sure that you have room for this light at the barrel due to the larger size lens area.
Answer: yes
