I just ordered a couple weapon lights. One of them is a WMLx I'm planning on putting on the KAC SR-15. Can't wait to see how it works. Lots and lots of great reviews on this light!
I've only seen one guy who "bashes" the Inforce lights and that's becuse he dropped his rifle (or stepped on it? Can't remember) and the housing of his FDE WML cracked. Big whoop if you ask me, the guys a Surefire fanboy anyway. I say take better care of your gear. In fact I've heard of these lights taking WAY worse. Besides, from what I undertand, Inforce has outstanding customer service and they'll gladly fix or replace your light if it breaks. I like Surefire lights too but damn... I just bought a 500 lumen WMLx AND a 775 lumen Streamlight TLR-1 HPL for less than what I'd have spent for one single Surefire M600 Scout!
I also read somewhere that Inforce had an inferior run of housings, only in the FDE color, which lead to cracks and they were happily replacing them with apologies for their customers. Yes, these lights are not as "bomb-proof" as some of the metal ones. It's a trade off I'm willing to accept considering you're getting a 500 lumen weapon light that weighs in at 4oz. Light, mount, switch, batteries and all! Add to that, it's made in USA and has a lifetime warranty...what's not to like!
