It does work - FIREFIELD FF25009 CHARGE AR GRN LAS/FL

Ok so I have the red one with light but same idea different color, so it works hold zero make sure you zero then a bit of blue thread locker will hold zero no matter what great for gas masks that’s the one and o my reason I have them and the ir helps with nods but so price is great I have a Steiner dbal now it’s no where near threat quality but it still functions in the same principle does the same things not as well but does do the things. If OpticsPlanet would send me some to test further because I don’t wanna destroy the ones I paid for, for my kit I’d love to test further like mud water rain swamp basically the things they’d run into daily. Now most of these I have ran threw and it’s holding up. The only issue is that the pressure plate is junk and I seeped in port and use switches on sighting system. And I don’t know how they’ll hold up. I’ll update if it blows up or fall apart. At this time and 1 year in to owning I recommend if you need it for the specific purpose of price and aiming while in FHA’s mask or ir for nvgs.
