Light modifiers
The polarizing filter is for intense light conditions like in desert or arctic environments. By reducing glare, one can see better into the shadows. This also makes different colors more saturated, again increasing visibility.
The kill flash is visible as a screen which is a disadvantage but by r...

Sorta works, but less than ideal
Bought this to see how it would help the M21 with odd lighting conditions, where the optic is too dim for what you are aiming at. While technically it does work, it almost becomes an occluded eyesight, and when rotated off, it still darkens the view thru the optic. The light that attaches to the M21...

Perfect product
Great product . Works as advertised. I’m able to dim it just enough to to see the reticle going from dark to brightness. Fits perfectly and is easy to install.
Would recommend: Yes
m21 polarizer kit
Don’t waist you money unless you like to see the honeycomb when you look through the sight
Would recommend: No
good product and works
This product works great, but does wash out your site window when in use, I feel the REM 21 light emitting diode attachment works better.
Would recommend: Yes
Brings The Reticle Out
While plastic, it works well, but I'm dubious to its durability. If you've trained in Occluded shooting, this makes the M21 very useful when aiming from a poorly lit area into a brightly lit area.
Pros:
- works
Cons:
- plastic
Would recommend: Yes

Bought to bring new life to an old military surplus sight.
Improved the view out of my old M21 10 fold. Makes the triangle more clear and defined in bright conditions. Easy to install and use. Highly recommend for anyone wanting to make an old M21 more usable in all lighting conditions.
Would recommend: Yes

A must have!
If you own a M-21 reflex sight you know the biggest downfall of it; so you can either get the led battery attachment (which I own and highly recommend it too) or at the very least this product! At its maximum setting, it does turn the FOV almost completely dark making the reticle look much brighter, so while shooting with both eye open (as you should) the brain would superimpose both images and it will appear as if you are looking and seeing the target through the sight, but if you close one eye (don't do it) you will see that it is almost blacked out and you won't see the target nor the surrounding environment! It also makes the sight look ever cooler lol!
Would recommend: Yes

Small piece that expands usability...
Got this as part of a package with the flashkill and polarizer...polarizer works well w/o need of batteries to attenuate bright light areas when viewed from darker areas. The flash kill is to lessen reflections that the front lens might show...works about as well as any flash kill.
Would recommend: Yes
