    Back in June, a good friend suggested I start saving for an AR-15. I told him that with my tight finances, the buying of a complete rifle was way out of the question. He then suggested that I at least ordered a lower receiver and go from there as money allowed. So I did. It was June 16 when I placed my order with DPMS for a complete lower with the standard A-2 butt stock. Yesterday my lower receiver arrived! I realize that even though it is not the complete rifle, I am still excited about it! I am planning on buying an A-3 upper with a match barrel in a light contour (if possible?). I was told the 1:8 twist would be the best for the 55-62 grain bullets. I also want to have free float handguards. I have never owned an AR-15 before, but I can tell you now, I will be scrimping and scrounging so I can get my upper receiver ASAP! Is 1:8 better than 1:9 twist for the 55-62 grain bullets? Thanks for any info you think may be helpful in my AR plans!

    Check out ar15.com, they have all the information you need, and the equipment exchange area of the forum is a good place to find deals.

    I'd look at a 1:7 upper for all around use, but 1:9 would work.

    Don't go over board and get yourself a match type upper, just get a 16" government profile upper or a lightweight. Don't get a Heavy Barrel(HBAR) as you will hate the extra weight.

    Brands to consider would be Stag Arms, CMMG, LMT or Sabre Defence. Plan on spending $500-600 for a complete upper with out free float forend.

    I really prefer 1/8 twist, but it's not all that common. 1/9 works great for me though as I shoot mostly 55gr ammo.

    Here's a link for a DPMS upper at Midway similar to what you want. I have the 16" bull barrel model and it is a very good shooter. Keep in mind I have lightweight .223's so this was bought for bench and varmit shooting off a bipod, weight didn't matter to me. They put them on sale occasionally for $389 or $399 which makes them a real bargain.


    1:9 twist is good at least up to the 64-69 grain range, 1:8 and 1:7 for bullets above that. All three of my .223's are 1:9 twist, but I never shoot anything longer than the 60 gr. Nosler Partition. Uusally I'm shooting 45 gr. HP, 50 gr. HP or 55 gr. SP loads.

    1-8 was the big gotta have twist for Match shooting when 69 grain bullets were all that could be had.

    Experimenters found the 1-7 twist would stabalize 75-77 grain bullets and do so accurately.

    1-9 was found to stabalize all bullets from 50-64 grains.

    If you plan to shoot a lot of 50-62 grain stuff choose a 1-9.

    If you have the ways and means to afford big batches of the 77 grain Black Hills ammunition by all means choose the 1-7 twist.

    Most of my rifles have 1-9 twist barrels right now.

    If 77 grain ammo comes on the market cheap and available in large batches, I will rebarrel to 1-7. HTH
