But do the commercially available FN rifles qualify as TDP or TDP equivalent?

Add another one to the FN camp.

I don't think so. Nevertheless, of the two choices of the OP, FN is the one I would choose. I never thought the day would come when I would turn my back on Colt's AR15s, but...

That is impressive, WARPIG602!

Tell us about the ammo used and how you rested the rifle to shoot those marvelous groups. please?

Yeah, Chris Bartocci says he thinks that overall, when it comes to ARs, barrels with machined rifling are more accurate than barrels which are cold hammer forged, but my personal experience with ARs has been the opposite. The three ARs I own (built rifles) which have Daniel Defense barrels are impressively accurate. The two rifles I own with Colt 6920 heavy barrels (twisted 1:9; one factory upper, one built upper) come close, but the DD barrels are king.

I have never done any real, test plan type of accuracy testing with AR's but I will say this. I built a few uppers with DD barrels and they consistently outshot my factory Colts. Better overall groups, tighter groups after longer strings of fire. Colt makes an outstanding barrel. I've shot Colt M16/M4's with literally tens of thousands of rounds through them and they all qualified. But you could tell they were getting old. The DD barrels just seemed to keep consistency over, and over, and over again. Again, I can't quantify this with numbers or charts but every rifle with a DD barrel I have built or shot is consistently good.

If I ever got back into "building" AR's I'd use a DD barrel.

I've only been around a few Colt barrels and a few DD barrels. Comparing these two brands, I give the accuracy nod to DD. However, both barrel brands were for carbine-length barrels, not the competition type for longer distances. I've heard that the truck-axle profile Colt target barrels are pretty accurate -- but again, no direct experience there.

In my experience with ARs used in precision steel matches, the most accurate barrels have been rifled barrels, not CHF barrels. Most of my barrels are/were from Wilson Combat -- they are button rifled. The Wilsons have shot extremely well out to as much as 800 yards in competition, formal training courses, and personal practice. Even better are my cut rifle barrels from Bartlein and Krieger. There are other brands of rifled barrels which also shoot with great accuracy.

I can talk accuracy figures for my various barrels, but some might dismiss then as one-offs or BS. I have posted more than a few pictures of AR15 targets in the "long distance rifle discussion" thread.

My Ballistic Advantage 18" fluted SPR barrel will ring a 10" steel plate at 400yds all day if I do my part. I ran out of optic on that rifle before I ran out of barrel (4-14x). I also have a 12.5" DD and it doesn't disappoint.

Thanks Para. I have 3 older LE6920s and was thinking of getting an FN but since it's subpar to TDP, I'll skip.
