Looking for some suggestions on this project, my goal is to effectively punch a target at 1000yds using AR platform.

I'm learning stuff everyday in my research but I hope I get more suggestions and solid info from here.

My original plan was to plug a .308 heavy bull barrel 20' or more with a twist that could handle the heavier loads that I presumed to go that far. As I have read some say yes, others say no due to wabble and so forth. I was turned on to the .260 rem and the 6mm family.

Everything I have read on these seem to be a better choice for hitting a tango that far. Right now I have found barrels and complete uppers with bolts for those rounds. I was wondering if any LR shooter had any advice on these rounds, barrel twist, length and parts I should get for this build.

Some research I have conducted I could get a complete upper and put it on a normal Lower or get a new BCG and re chamber a barrel if need be. Thoughts?

What is your budget? You might want to take a look at the LaRue OBR.

Nothing over 4k is my goal. I say that to make room for adjustments. Obr is cool, not what I'm looking for though.

welcome to THR

save yourself a LOT of grief and go to GA Precision and get their GAP10 in 6 Creedmore. Then ask them if they have any of the HDMR scopes left at the group buy price. Together, should be right at your budget.

I would be looking at a DPMS LR-260....or LR-308 or any other AR in 308. I think the 260 is superior ballistically at those ranges though.... $1500 = $1500 scope = $3000

if i had that to spend id look into one of specializeddinamics.com 260 rifles. i saw a video of him shooting one silenced at steel to 1300 and conecting every shot. hes a serious shooter. i wouldnt buy a semi auto 308 for it there are better choices if thats gonna be a target gun.

I think someone fed you some manure. I’ve shot a 308 with a 1 in 10 twist using a 168 SMK to 1000 yards. A 175 or 180 gr SMK might have been better. An AR in 223 will push an 80 gr. SMK to 1000 yards. A 1 in 7 twist will do just fine.

Looking for some suggestions on this project, my goal is to effectively punch a target at 1000yds using AR platform.

6.5 Grendel is the best choice for 1k yard target shooting with the AR platform I have used. My Noveske 21" N6 well do 1K but is effected by wind more than the Grendel.

So itbseems to me I'll be fine with 308,260,6mm family.

So 20' or above for barrel? Between 1:8 and 1:11 fir twist?

I'd look at the Les Baer sniper/match in .308. Shotgun news had an article a while back with some very impressive claims and the weapons comes with a 1/2 moa guarantee.

I'd be looking at 260 Remington DMPS AR10 FTW. Better long range ballistics than a 308.

With a 308, you'd like to have a 24" barrel for the extra velocity. 20" is borderline. The 308 with a hot, high BC, round out of a long enough barrel can get there, but a 260 would be better.

A 20" 5.56 falls subsonic well before 1000y, for most loads.

Alternatively, you could look into a 6mm AR15. That might be my next long range upper.

I would second looking for one in .260 Rem. It is a great cartridge for that distance. At 1000 yards, it is better than the .308 in every way.

Seems to me that I could use the .260 rem or the 6mm family and still achieve my goals of LR shooting. I thank all for their advice and replies..don't worry 308 will be the next build...I will be hand loading all my rounds once I get the equipment and stuff if there is anything else to pass on so ican right them down please do it.

Ok I'm a little flustered I can't seem to find to much information on the .260 AR stuff on the net..I found more on 6mmBR then the .260. Help?!
