So Fulton Armory is selling 16" & 18.5" .308 barrels that are looking pretty tempting.  I'd read that a 16" DPMS barrel weighs ~2.75lbs.  So by swapping to their lightweight 18.5" barrel, and going from a 12" DD Lite rail to a new Troy TRX, I could knock almost a full pound off my rifle while bumping the length out over two inches.  That's tempting...

So anyone try them out yet?  How much worse do you suppose a LW barrel would shoot when compared to their full profiled one?

You are correct that the DPMS AP4 barrel weighs 2.75lbs., but that weight includes the barrel nut and the front sight post. I'd say that they'd be about the same weight after removing them.

Good barrel. I've had one for a while and it is a great shooter. It is al least 1 moa, rings my 2" swinger at 200 yards everytime. Probably could do better but never serious on paper. In fact, I'm giving it up in a trade this week and I'm gonna get another one for my MaTen. Also remember, its chrome lined.

i got mine with a Krieger barrel , but when i called back to ask for spare last year they said they can't get the Krieger's now and they had their own in house barrels but he would not tell me who made them or where the blanks come from. I will buy another kreiger though , its well worth the extra $.

They get their barrels from Criterion, which is owned by Krieger if I remember correctly.

Been using the 18.5" stainless NM barrel for over a year now.  Here's the final config on it:



Here's the initial scope sight-in for the rifle:



It's a shooter.  Great barrel.

Who made your bolt carrier? And does it have forward assist serrations? What type of gas block did you have to use? I need these two parts to finally complete my AR10 build, and I want to how much more $$$ I'll be in it for.

Seeing that Brownells is now out of stock on them, I figured it's been long enough to bump this thread up a bit.

Not necessary on a DPMS pattern carrier/upper, but it is present on Armalite and most other 308 AR's.  The DPMS FA pushes against the shoulder where the diameter of the BC changes, which is why it is so far forward compared to other companies 308 AR's and AR15's.
