Three Prong flash hiders..... > Rifles, Uppers, Lowers, Barrels, and more

Posted: 9/2/2004 12:06:55 PM EDT

I have a post ban clone of an SP1 that currently contains an "A2" style muzzle brake. Ideally, when there in no more ban to worry about, I would like to replace this brake with an original three prong flash suppresor. Anyone have an idea where I could find one and what the cost may be?

Thanks in advance,

Gary

I've no clue what the item in the above photo reproduces.

It's not a XM16E1 "3-prong" flash supressor though.

It may be a reproduction pre-1963 Colt's AR15 01 flash supressor.

The initial Army contract, the "one time buy" spec for the XM16E1 had this change from the prototype AR15: "The distinctively sculputural open prongs of the Colt model 01 were beefed up somewhat, to avoid bending or breaking during rough handling." [Black Rifle p. 136]

That is a repro of the "duckbill" flash hider used on the Colt/Armalite model 01. Real ones are hard to find.

I have never seen a 3 prong FS in person, does the 3 prong FSs have the "flats" for then wrench? every picture I've seen doesn't have em. Does that mean when using 3 prong one has no choice but to use a USGI 3 prong FS wrench?

You are correct, you have no choice, unless of course you have a very strong grip.

I assume in that pic that is a real duckbill?? They are fairly easy to make from a standard 3 prong, but are retro-cool. Early M16's are tha coolest!!

Anybody know how the 3-pronger should be radially timed?

Yes, you needed a wrench that fit between the three prongs.

No need to time them, just like the A1 birdcage.

Nice photo of the old wrench too.

The only M16 flash supressor that needs to be indexed is the M16A2 compensator and that just needs the middle slot generally at 12 o'clock.

I would imagine the best setting is for the prongs to be at 12, 4 and 8 o clock. That is if you want the FS to look upright and symmetrical.

Correct, they are both held on with a lock washer.

"Timing' does not matter on the 3-prong.

I thought I was the only one that had respect for the old 3-prong. I call it the "poor man's vortex".

The 3 prong is very good at flash supression.

I'm there too man. 3-Prong is the ONLY way to fly. I'm putting them on ALL my rifles after the 13th.

Tested side by side on identical barrels the 3 prong gave as much flash as the A1 and A2 and much more than the Phantom and Vortex.

Tested by whom? With what ammo?

By me and another ARF member. Ammo was SA ball.
