when were they first used?
I know knights made them popular but when was that?

I got my first one in 1999 from C-more, a 12 inch.
it is probably the heaviest one on the market. and at that time it was $299.

it's weight is probably the reason for we rarely not seeing them in pics.
it is a very good rail.

anyway, does anybody have an idea when they were first used and then started getting popular?
I was on ARFCOM In the beginning and didn't think of this then.

Here is the Standardization memo for picatinny rails marked 3 FEB 1995.

And if I remember correctly the US had M4 flattops before the end of 1994 (dunno if they were for testing, or officially adopted?)

Edit: I also just found on an obscure site that the NSN for KAC's M4 RAS was entered in 6 AUG 2005

I wondered because I got those rails and didn't remember seeing them prior.

ARMS rigid frame was probably one of the first, the predecessor to the SIR.  It was bulky and ugly, ahead of its time though.

anyone know when they got popular? after knight's?

I got mine in 99 and wondered if I was on the boat early or same as every one else.
I never see a C-more rail like it, it's heavy.

I got my RIS in 2000, rail handguards definitely weren't the norm back then.  I think KAC has much to do with the popularity, for a while there was only KAC and ARMS SIR, DD was not so well known.
