Complete Upper question

[Cero]

Looking to buy a complete upper and I've seen some that I like. However they all have a2 flash hiders. How difficult it is to remove?

If it's not welded on, it just unscrews.

Put the rifle in a vise gently, and turn it off.

Once it's off you need to then pin a brake on, or grind off the threads, or get a pre-BSN lower.

Not necessarily. If you are looking at 14.5" uppers, the FH may be pinned/welded already. Check with the vendor to be sure before ordering. It can still be removed, but will be a bit more work than just unscrewing it.
