This cap came with my vltor a5 kit and slips right over my surefire light - with it in place no light leaks out, so be carefull not to leave it on because it will get hot. It comes off quick but stayed on my 12.5 in ar10 with that muzzle break - finally keep that light clean when I'm not using it is nice.

There are probably white ones that will allow enough light to illuminate a room without blowing out a eotech on low settings etc.

My local hardware stores have these too.

If you need something quick a piece of painters tape over the lense works great but it will fall off with a couple seconds of light use so use sparingly.



a quick about the sights because someone always says - they are tritium back up and carry overs from using battery powered optics for hd - I can find the rifle and aim in the pitch black - engage confidentially down the length of my home and at 100 yards if I aim for your left hip, I'll hit center mass - know your holds.

Bro I honestly dont know if this is a joke or not. Why aren't you just using a normal sight? For the light if its for HD that is when you want a light so why are you covering it?. Also you could just partial unscrew the tail.

I appreciate the concern for White light NDs  but they aren’t that big of an issue and if they are you might need to reconsider your switching set up or grip or something.


Or unscrew your tail cap whilst you crawl through the jungle towards the unsuspecting NVA position

Agree.  Same here.
