I want to install a Smith Enterprises Vortex flash hider. Which threads does this rifle have (10A4BF)? There are 2 choices on the Brownell's site:

Check your manual...if not...call ArmaLite and give them your serial# to be absolutely sure....
When in doubt..always consult the "Home Office" but check your manual first..
and their tech notes on their site...

Thanks for the advice. I went to the Armalite website here: www.armalite.com/ItemForm.aspx?item=U10A...ca-bfa1-afcb5ddcc9ba
The description for the correct uppper shows the thread pitch as 5/8 x 24, so I'm good to go.
