What material is used for the window in current SureFire G2 flashlights?

Justin Case · Nov 14, 2008

Lexan? AR Pyrex? Something else? The camo G2s on sale at Gander Mountain are tempting. If it is Lexan, is the window end-user replaceable by unscrewing a retaining ring?

Thanks.

I just got one of those from Gander Mtn. Window is plastic. The bezel does have notches in it, like for a spanner or key but I haven't tried removing it.
Hope this helps.

Ooops. Upon further inspection, the retaining ring does not have the notches to assist with removal. Sorry 'bout that.

Purchased a new G2 last week. It has a Lexan lens and there are no notches on the bezel ring. Looks like the lens cannot be replaced.

If you want a pyrex lens for your G2 , as long as its OD, black, tan, you could always call Surfire and request a bezel for a G2Z combat light. It will fit perfectly and then you will have a pyrex lens. I did this for my OD G2.

Yea the lens is made of Lexan (high-grade plastic)

G2 = Lexan
G3 = Pyrex

My recently purchased G2 appears to be pyrex, I was really surprised by that. However I cannot confirm, I will have to take it apart one of these days.

Just tap it with a coin. If it clinks like glass, its pyrex.

G2Z is also pyrex.
