| I have a DPMS .308 setup with the stock 16 inch barrel. Looking to help this rifle reach out a little further...say 1000 yards. What is a good length and type of barrel would I be looking for? |

You can shoot 1000 yards now, just not accurately. 24" is an absolute minimum barrel length for .308 for use at 1000 yards IMO. 26" and even longer would be better. My 1000 yard .308's have a 27.5" and a 30" barrel (bolt actions). The 16 inch barrel allows the big framed AR to be maneuverable, a 24" does not. I have a 21" Noveske AR-10 and it's a beast to live with and still isn't more than a 800 yard tool as far as great accuracy is concerned. People are in awe of 1000 yards for whatever reason. I guess it's a nice round number. If you really want to be competitive at that range buy a dedicated F-Class bolt action or be satisfied simply ringing steel on occasion with something that's "close enough but no cigar". .308 is a 800 meter rifle unless you want to go with a very long barrel. |

16" rifles can be used accurately at 1k of the shooter and the rifle components are up to it. While it would be easier with a longer barrel it's not impossible with a shorter barrel.
Try the 178 BTHP, 178 AMAX, or 175 SMK. All 3 should get you to 1k better than any 168. |

If you are a reloader, you can hit 1000 yards at 16" just barely, and you have to push every edge of every envelope to get there.
But in general the 20" barrel is the required minimum to get 1000 yards accurately (1150 yards at MACH) A 24" barrel can reach 1100 yards accurately (1200 with the new TMKs:: 1350 MACH) |

I would definitely have to disagree with you, I shoot my 20" barrel 308 out to a 1000 yards basically every weekend and have no issues making it there with 175gr bullets moving 2,650 fps. In fact this past Sunday I went 19 for 20 at 1000 with a 6 shot group that measured just over 12". Granted 6mm / 6.5mm are ballistically superior at long range the 308 round can easily do well out to 1200 yards. To the OP, I would recommend a minimum of a 20" barrel, longer if you want to have to dial less elevation to get there. |

To the OP, I would recommend a minimum of a 20" barrel, longer if you want to have to dial less elevation to get there. I would respectfully suggest that a 175 grain .308 traveling 2650 fps is at least 1.5 grains of powder over maximum pressure even when using Winchester brass. Any other brass would be worse. A 26" barrel might make 2650 fps driving a 175 at maximum, most will top out around 2600 - 2625 fps. I consider 2600 fps the limit from a 24" barrel. That would turn into 2500 fps from a 20". I know some like it hot. If I need to go faster I get a bigger gun. |
