Brightness:
It's as bright as a RMR. Brighter than holosuns. Most holosuns can get to the "down 1" setting of the RMR, but this gets all the way up there.
Window size:
The window is noticeably larger than the holosun 407k. It really feels like looking through a clear RMR sizewise.
Glass clarity:
No blue tint. Very clear and clean, like a deltapoint.
Mounting system:
Holy crap it comes with about 10 sets of screws for every single gun in the world. They are nice Torx screws too, so you dont have to buy the dot, then scroll around the internet looking for the size of screws for your gun. It also direct mounts to the Glock slimline MOS system (43x/48), the S&W Shield, and the Sig 365. It's great.
I would 100% choose this over any other K optic.
The only negative the defender has, is the refresh rate of the dot is a little slow. When the dot is dim, you can notice it. When the dot is full brightness, you don't see it.
It's literally better than the holosun k by every metric that I can think of. Especially when it's on the market for $250.
I really don't think you NEEEEED to have a enclosed emitter for CCW. Your belly lint is the only environmental hazard this thing is getting exposed to.
