Are there different lengths of twist-on flash hiders?

I have an FAL barrel that features a bare muzzle with no threading and a lug under the barrel. I assumed it was a G1 barrel, so I bought a G1 twist-on flash hider, only to discover that the lug is too far back to lock the flash hider. The locking section almost doesn't reach the lug at all, which is 3.45 inches back from the crown. Also, the barrel is not chromed.

Internet searching has produced no leads, so does anyone know what I have here, and whether there's a twist-on flash hider that fits it--or is that just a bayonet lug?

Edited to add that the position of the lug makes it look like it might be a Falklands-era Argentine barrel.

Plain muzzle lugged barrel

Fang, What markings are on the barrel, If None, Look on the wrench flats on the back if their are any there.

I'm surprised we don't hear about this happening more often. It is such a simple error, poor FNG buys a "G1" barrel that's really Argie. Don't be sad, you have a great barrel and you don't need a FH.

Top: G1 barrel with detachable flash hider lug
Bottom: M2 type barrel with bayonet lug.

Keep in mind the G1 barrel has channels cut for the bipod and the M2 type is not cut for the bipod.

added that pic to my files. will make explaining much easier. Get asked that question a couple times a month.


Of course, having both lug and treads would be correct for a factory retrofitted izzy.

Belgium M2 barrels

The Belgium M2 barrel also has a special cut JUST FORWARD of the BARREL WRENCH FLATS at top dead center that is bullet shaped. I think Nebs had one for sale about a month ago. I think that was done as they used the type B Gas cylinders that were thicker in radius early on in production.

Fang, save that barrel and build yourself a M2 type FAL as time and funds permits. My all-time favorite.

I would, but this barrel was purchased cheaply because it had a shot-out and pitted bore; I got it to bore out and reline for .22.

And also for the Bundesgrenzshutze G1s that were threaded for H&K G3 flashhiders. I ran into some of these around Rötz and Weiden on the "Iron Curtain" West German 5KM border zone around late 1966 and '67, also at the Bundeswehr small arms center at Meppen in the Summer of '67. I suspect, but don't know for certain, that it was the barrels that were threaded to accept the G3 flashhider rather than the flashhiders adapted to fit existing FAL-type barrel threads. That is to say, I think that the threads were applied to previously unthreaded barrels, though if someone knows differently for certain, I stand ready to be correcteed.

Lots of interesting goodies were floating around the BGS in those days, and all sorts of interesting things going on. And then after the "Prague Spring" of 1968, on 20–21 August Eastern Bloc armies from the Soviet Union, Bulgaria, Poland and Hungary—came a-visiting the Czechoslovokian ČSSR, and that was the end of the Chech political liberalization of their Communist system.

Would make sense since the OD of the barrel is M15. They can be threaded with a pilot from the muzzle without pulling the barrel to lathe turn the OD down to 9/16ths.

I shortened barrels and put HK flash hiders on a lot of galils before I had a lathe.

And you've probably seen the pic of the training range magazine that is G3 on one side and G1 on the other.
