What is this gadget?

Behind the 3 prong? Looks kind of like a gas block, but couldn't see a retaining pin for a tube.

Profile of the barrel looks odd and appeared to have the front sight soldered too.

For bayonet?

I think it would interfere with mounting a bayonet.

Did they ever use rifle grenades on m16s?

Mounting point for that Israeli anti bunker grenade thing?

My guess is some retarded aftermarket flash hider / bayo lug combo that isn't intended for that rifle but happens to have the same thread pattern. So much goober crap just like this made during the Clinton years it isn't funny.

Yes but no launcher was required just the 22mm flash suppressor. At first I thought that might be for the RAW bowling ball rocket launcher but looking at that one it just slips over the flash suppressor so no don't know.

The Nick Nolte movie Who'll Stop the Rain has a really good M16 rifle grenade scene, he actually ejects the ball round and replaces with a grenade cartridge which you better do.

The tapatalk'd picture looks like crap.

It does appear to be an improved 3 prong. The gadget has a hole in the rear that appeared to be gas tube size,but couldn't make out a retaining pin. The barrel in front of the sight was heavier.

That was at the Thomas D. Clark Museum in Frankfort and was on an M16 lower.

Later that day we went to the KY Military History Museum and they had on display what was supposed to be an M16A1 donated by the Army that as near as I can tell had a C7 upper(round head assist, deflector, and skinny barrel that I couldn't get an angle to look for stamps) that they had stuck a triangular forearm and it was on a full auto lower as well.

It looks like an old bipod mount used before the clothes pin mount was developed.

So it's bad to shoot a rifle grenade with a live round? Yeah, that is probably one of those things where you better read the manual. Can't even remember the last time I saw a rifle grenade, was probably late 70s. Did they use a standard blank or was their a special rifle grenade round? I always assumed they used a blank.
