British Flash Hider

[G2]

Any Help??
I have a Century L1A1. I just purchased a British Flash Hider w/ timing washer and pin. Believing the only stupid question is the one not asked, How do I secure the flash hider? I have installed threaded etc. but this just slips over the barrel and the timing wash and pin holds it in its proper location (rotation) but you can still just slip it off. Any help will be much appreciated.:bow:

are the threads too small in diameter, maybe?

The timing washer goes inside. There is a small disk which fits into the bit on the rear and is held in place by the pin. This disk, or key, fits into a slot milled in the barrel. You should have 4 pieces for a complete flash eliminator.

I have the flash hider, disc and pin. There are no threads. I installed the disk/pin and they engage the milled slot in the barrel. But the barrel slot is only 3/8" long and goes to the end of the barrel, this alows the flash hider to slide off the end. Make sense?? In other words, there is nothing holding the flash hider from sliding off. the slot is cut past the end of my barrel. I will try to post pixs.

Yes, post pics.
Sounds like your muzzle threads have been removed for a post ban configuration. If this is true when we see the pics, you will need your barrel's muzzle threaded, the slot milled in place further back, and it will have to be 'timed" to tighten on the threads in the correct rotation position. Then the disc and pin are installed to engage the slot prevent it from unscrewing.:uhoh:

Yeap sounds like you dont have any threads. I would waste my time with one of those adapter do dads that are held on with set screws. Everyone I have known to use them said they blew off while firing.

BTW the disc and pin actually keeps the FH from tightening on a set of RH thread. It is completely opposite of a LH set of threads. They will actually loosen while firing.

Thanks guys...You are right. upon close examination of the FH I noticed threads on the inside. Man an I doumb or what??? But.....I have a plan. I have been planning on DuraCoating the rifle any way, so I will probably tig weld the FH on to my barrel. Since I am experienced at tig welding as well as Duracoat, what the heck. This is the first Fal for me, had a ton of everything else, Ak's etc. Man this Fal is a sweet shooting rifle. I much prefer the .308. I have used the .308 as a deer round here in Mich for years.
Any way, Thanks for all your help......:bow:

Be very carful tigging the FH so as not to create a layer of scale inside the rifling from the heat. I have seen this happen even when brazed.
Just be careful! :-))):wink:

My Century was the same way. I just cut the barrel back behind the old key slot, re-crowned and re-threaded the muzzle, and re-cut the timing slot. Parts went on with no problem.
