I would like some advise, I am looking at these three barrels. I am finishing a build and am shooting 168 grain FGMM for the paper and will shoot whatever 147 -180 grain I can find at a good price for fun. This rifle will probably only see bench and prone shooting. Max range would 500 yards + or - . I remember the old DPMS LR-308 with the heavy barrel and it was a good shooter, but heavy. Lilja makes nice barrels and the 18 " & 24" 1:11 twist and easy install for my smith, but 4 1/2 pounds heavy on the 24. The Shilen is a 20 inch 1:11 out of Ranier Arms and is on back order for now and I am not in a hurry, and the Criterion I read is a good barrel but I am not that familiar with a 1:12 twist on the 308. They offer a 18.5 in a 1:10 and a 20 -24 " in the 1:12 twist barrel that appear to be also an easy install for my smith. I also have read mixed reviews stating that barrels coming from Fulton Armory do and don't have the M-4 style feed ramps. One positive is that they area Wylde Chamber so it will shoot the .308 Win and 7.62 NATO ammo that can still be bought in bulk. I will try to call Fulton Armory tomorrow and get the correct answer on the M-4 feed ramp issue. I did see another thread about Criterion barrels here,but I don't hijack threads. Since I am only shooting 500 yds max an 18" should do me fine.
