Britishs AR-15 and rifle grenades

Gentlemen!
Used Brit's rifle grenades from their AR-15 rifles in mid 60th military conflicts? If yes, what?

As far as I know the British were using the FAL during this period, as always though, I could be wrong.

I know SAS used XM177E2s for awhile, as they had nothing comparable before L85A2

I've seen pics of Gurkhas around that time period using M16s as well.

No idea on the rifle grenade though.

With the existance of the M203, i doubt it.

I'm sorry guys I'm not even aware of rifle grenades for the AR family. Especially from that time frame. I know there was some trial stuff but nothing was standardized. Was it???

Original Armalite/Colt brochures show grenade launching with the M16. Same grenades as Korean war. There is a 5 or 6 star shaped spring that mounts behind the flash hider to secure the grenade when it was slipped over the muzzle. I used to have one in my stuff.

Yes, I'm aware of the star shaped clip mounted behind the flash hider. I just haven't seen anything on grenade launching with the ARs.

The Book "Black Rifle" shows a few pics if I recall. I'll check and do page numbers. My scanner is shot.

I have the books, I'll look it up.
