It is a Gen 2 but I didn't realize it was supposed to be 800 lumens. I thought it was 600? Hard to tell for me because I have a Streamlight TLR-1 HL (1000 lumens) on my pistol and my handheld light has settings from 3-1000 lumens. It's noticeably dimmer than my Streamlight, which I don't mind. I knew going in that I was getting lower lumens. Streamline is definitely the best selling point/strength for this light IMO. I like not having to deal with wires or a pressure pad but I recently moved my AFG back a little bit and now I cannot activate the Inforce without moving my hand, which I don't like. I also have it mounted on a Magpul cantilever mount, so I could potentially move the light closer to my AFG and use a standard mount piece, but then I don't think the placement of the light will be ideal.How do you like that Inforce WML? Is that a Gen 2 800 lumens? That's probably my next and last purchase for my AR. I have a pressure pad set up now but I think the WML would streamline things a bit.
I've actually heard some not-so-great things about the Inforce WML but I also heard these issues were mostly with the Gen 1. I'm still a little skeptical about the polymer as all my other lights are aluminum. I got it for $120 and my next choice (Streamlight TLR-1 HL + pressure pad setup) will be significantly more expensive. I definitely like the form and function. Just keep in mind that where you place your support hand is an important factor to consider. I will say that if this thing was aluminum I would be 200% more confident about it. With that being said, I've put around 600 rds. through with the light mounted with no issues so far, and as you can see it's essentially riding the muzzle device.
Sorry for the lengthy response, hope it was helpful. What light are you currently running?
