Question: Anyone know if this works on ar 15 platforms?thx
Document: The light is very bright. Works great. The battery they sent with it was dead. But no problem I had a new one. Now the light works great.
Fits very tight on my glock 20 and is extremely bright. I highly recommend to anyone wanting a good light. Well worth the money
Works great and uses double A batteries.It has hi low and strobe but I only use high.There are other lights that take double A batteries so check around for the best price.
I bought this light for my dad for fathers day. Only problem is that I didn't know that his glock 21 didn't have a rail. Later on I will buy him a new frame with a rail so it should fit then. Other than that the light is very bright and looks very tactical!
As the other reviews say,this is a great value. I have it on my gen3 g17 and it fits great. A bit tough to get off, but not too bad. One thing I did not see on the reviews is how the light performed under pressure. I have ran about 50 rounds with the light on and it still works perfect.
It held in place. Light comes on when I need it to, turns off when I turn it off. 50rds through the gun and it still works. Time will tell in the long run, but at less than $40, if I can get another 300rds out of it or 1yr of use, I am ahead.If you don't expect this to function as a Surefire this will be a great value to you. This is a flashlight that mounts on your gun. Nothing more, nothing less.
This flashlight is awesome. I have a Smith and Wesson SD9VE and this light fits on it like a glove. There is no wiggle room and it seems as if it's going to be hard to pull off. I am very pleased with this product. The brightness of the light surprised me as well, watch out for mirrors haha. I would recommend this light to anyone.
I got this for my P229 based on reviews. I knew full well it likely wouldn't fit but I didn't know how close it would be... very very close. The corners on the frame above the rear of the rail are just barely too forward to allow for positive lock on the rail. The housing of the light is tough enough to avoid scratching and dents but maliable enough to manipulate with about $10 worth of tools.
This is a fantastic little light, it fits my Springfield XD .45 ACP perfectly and I didn't even know about the strobe setting which is fantastic. The light can also be switched on with the trigger finger (granted you're right handed) without changing hand positions which would be useful in a home innovation. If I had to niggle one tiny little thing, it's that; if you set the firearm down on it's left side, it switches the light on. Great value for money. I would highly recommend.
very good construction, VERY bright, solid all around. my only gripe, not a quick detach on MY weapon because the weaver mount on this light is just a little too tight. i have to unload gun then yank (and i mean YANK) this thing off; which, if i needed to take this off quickly in a tactical situation, would make it a little impractical. on the flip side, however, i guess it won't move while i shoot.
Answer: yes
