    I just bought a M-4 style doublestar ar. it has a 1x9 twist barrel . what is the best bullet weight to shoot for acc. i only have iron sights on it now and shooting m193 ammo through it . its not that bad but I was wondering if i could get better acc. out of it ? any help is welcome. thanks in advance:confused:

    Welcome to the addiction. I'm sure you'll soon find out that the AR platform is kinda like the Dallas Cowboys... People either lovem or hatem.
    Obviously I'm a huge fan... of the AR not the Cowboys.:confused:
    Anyway... as to your question, You'll need to get a scattering of all different types of ammo to really see what your barrel likes. The basic rule is that you need a tighter twist to stablize a heavier grain projectile. The 1/9 is reported by most to be really good with 55 to 62 grain. There are plenty of reports that bullets carrying more weight than that will start to tumble and keyhole the targets.
    It's almost a sure bet that you won't be able to stabilize anything heavier than a 69, but it never hurts to try.....;)

    I use a 1/7 barrel, and have had very good results with Prvi Partisan 69 gr BTHP's Cheap clean and accurate. YMMV

    Let us know how she shoots and congrats on your purchase!!!!!

    ps... Optics are cool... but iron will never fail and is all you'll ever need.. Just my opinion, and I'm usually wrong.

      ....practice, practice, and more practice.

      Things are seldom what they seem.

        While every barrel is different 1-9 inch twist barrels usually shoot best with 68/69 grain HPBTs. The typical
        favorite is Sierra's 69 grain MatchKing.

              I'm going out this weekend to get a little more practice. I'm just not able to go as often as I would like and need to. Both ammo and fuel are way to expensive around here. That's the hard part fittin the bill for it.
