Please identify 1969 period rifle grenade set

[breakeyp]

This showed up at a small show today. It is complete in a capped cardboard tube marked, "PRAC (INT-F) / RFL -- 40 / N / AA? 69.

The grenade body has the same markings as the shipping/carrying tube. With the grenade is a plastic packaged blank / launching round and an odd plastic sight marked 100, 150 and 200 yards. The sight has a circular cross section notch that must fit the rifle some how.

Is the N marking indicated Naval issue? I take the 69 to be a year date.

What does the sight fit? M16 or SA80 rifles? Where does it fit?

Is the grenade anti tank, anti personnel or ? Thank you.

Not for a M16.

Fal related perhaps?

Thank you. I failed to mention that the cartridge is 5.56mm Nato. How and what the odd sight fits is a puzzle.

That will clip on the rear sight, just can't find a picture of the rifle to explain...then use the aperture for the front sight. You know you'd do it by eyeball and estimate though, after firing a few...

Which rifle? Thanks, p.

That's the thing, they used to use the FNC but I don't see where it would clip on either. They use the 4500 SCAR-L apparently now...it's got a rail top. I looked at them but now evident place to attach. That's the sight though, seems to come with each grenade...

The navy had rifle grenades? I know it's possible, but ...

The SA80 wasn't issued in 1969. Not seen until 1985.
That little fellow appears to be of Belgian descent and is a variation of their 40mm Anti-tank rifle grenade that could be fired from any .223 rifle with a 22mm launcher. An FNC, for example.
Net search 'arp-rfl-40' for a whole bunch of sites with pictures.
What's the head stamp on the grenade cartridge?
