    Rainier is a good barrel as far as I know.
    Lilja is a top quality one...
    that being said, if six sigma only has the 16" max (they are a reseller for Lilja), you might call him to see if he has the 19" AR19 or the 20" AR740, the lilja web site has the 20" for sale now, buying direct. That's where I got mine from.

    Six sigma has a vendor thread on here but he (Rebby) hasn't updated it for a while. he is a nice guy though, bottom line for lilja you have a couple options as to where to buy.

    My $0.02 but I think the grendel works a bit better with the rifle length gas. Mid-length bangs up stuff a lot more due to the higher gas pressures at unlock. But there are better experts on here than I am... I pretty much stick with RL gas stuff.
