Just got a DSA FAL G1 kit yesterday. I figured that the old 21" Belgian barrel would be trash, but in fact, it was really nice. But I had already ordered a new 18" to replace it. I was a bit suprised to learn that the new barrel is an 18" Stainless Wilson barrel, w/o gas block or MB/flashhider. Do you think I should switch the barrels out, or leave it as is? I'm going to have to review the [US parts vs Import parts] to stay legal, so that could be a factor as well. Anyone here know where to find a matching stainless FH/MB for the new one?
