AR accuracy issues

[Byte Stryke]

as am I
I have had little/No problems with my DPMS.
99.9% of my accuracy issues are shooter related

I Would like to have seen a Target/card with the weapon fired from a sled/rest.
Nothing against OP but I find that they remove allot of the "variables".

I have no access to a sled otherwise thatwould have been my next step. I am a pretty good shot prone though. I can put a sub moa group at 100 yards with my M1A prone and slinged up.

I can vouch for him. He can shoot better than me most times.......but thats ONLY because he has a super match m1a

5moa groups for him is not normal. I would bet 20 bucks it the rifle in some way, shape or form.

Well my upper is in the mail being sent back as we speak, they said it had no problems and they tested it with 69 grain match ammo from Federal and Remington. Hopefully they included a target. They also said that 55 grain bullets are too light for a 1-9 twist barrel and I should shoot no less than 62 grain pills. Is this really true? It is a 16 inch barrel with a standard M4 hand guard. They didn't say how well it grouped. I should receive it Monday. It's about time though, they've had it since the beginning of January. I understand it has been cold, but this long to get it back? Springfield's turn around time has been 3 weeks tops for me, and I've sent stuff to them 3 times so far for various work to be done.

I hate to tell you this but they are wrong about the twist rate. It's the opposite. A 1:9 should work better with a 55g than a 62g. A 1:7 would be better for a 62g.

I have one AR that is getting better but I know how ya feel. I sometimes go back to what I call my sanity check gun. If the groups come back with it then I know it is the gun and not me.

I am not any kind of match shooter like some friends of mine but I do ok fighting the NRA HP targets. I also like a challenge so my poison of choice is a FAL. I have one that has turned out to be a 2.5 moa shooter if I do my part.

On another note my latest AR has a 1-9 barrel and seems to shoot the 55gr as well as the 62's. It was more sensitive to length than load.

i have a few different brands of 55gr. swing by the house and i'll put a shooters ammo box together for you. my SBR and the spouses ar shoot 55gr great and both 1:9 .
i found the 55 and lighter ammo say 52gr's really shine in my 20" 1:12

As stated above, the real formula concerns length not weight. But longer slugs are generally heavier which require a faster twist rate.

With the vertical stringing the first thing that came to mind was inconsistent pressure or the bipod. Have you tried shooting it off a soft rest with minimal pressure on the handguard? Pressure on a standerd forend will definitely change your POI.

Also could be bouncing around a little on a hard surface, but I'd expect to see less of a consistency in the shots with that.

another reason I suggested a sled.
