[QUOTE="budlight, post: 2095043, member: 2939"] 3000 is not realistic out of 16 inch barrel. I have lots of chrono time with AR's. You have 3 things working against you. The carbine length gas tube bleed off pressure very early in the pills travel and the 7 twist slows down the bullets travel. Then length of the barrel. My buddy tried and he ruined lots of cases with expanded primer pockets and popped primers. It also beats the crud out of the buffer tube weight exceeding much over 2800 fps 7 twist 20 inch barrels with rifle length gas tubes throw 55 gr bullets sideways through paper at 100 yards even decreasing the powder charge to 3000 fps. My rifle had to use 62 and above and liked 75 gr. I actually gave up on 7 twist and went to 8 and 9 in 18 - 20 - 24 inch barrels with rifle length and + 2 inch piston systems [/QUOTE]
