I personally have seen very little correlation between changing clamshell handguard to free float. My Colt 6933 still wears a drop in handguard that uses all the factory clamshell hardware and it shoots 1” or less with 70 grain plus Ammo.
I personally would contact Anderson and send it back with a sample target or two or at least pictures of targets.
There’s no reason it shouldn’t shoot around 1” in factory form.

No doubt that this can happen with a very consistent shooter who sets up each shot exactly the same.
But there is no doubt that POI can be effected but inconsistent pressure on the front rest unless free floated

Originally posted by Playa View PostI have had my AR for about a year and have yet to really achieve what I consider respectable accuracy out of it. I can get about 2-3 in groups at 100 yds and 6+ at 200.
I have tried all types of ammo from light 55 gr- to heavier 73gr and in between . Poi changes but the groups stay loose regardless. I’m certainly no sniper but I can shoot 1” groups or better with my other rifles.
I upgraded the trigger to a 3.5# Velocity single stage last feb. While it helped, it only improved to the stats stated, before patterns were wider spread than that.
Shooting from a bench with a Caldwell solo.
Surely a mil spec/ factory AR is better than that?
The fix for that problem, is either to hand load some of the same bullets I have been using, or see if you can find another bullet that is similar in shape, but I don't think you will find many others with the same shape. The bullet fix is a Speer 52 gr. hollow point.
The other option, is to replace the barrel with a 223 Wylde chambered barrel. Barrels with that chambering will shoot both 5.56 and 223 ammo much more accurately than any 5.56 chambered barrel. If you are going to do that, try to find one with 5R rifling. Then pick a rifling rate of twist that works with the bullets you want to shoot most often.
Another possibly problem, is the barrel might be loose in the upper receiver. I had that problem on another AR, I spent quite a while trying to figure out what the problem was, then finally removed the barrel and found it fit in the upper very loosely. I could see signs of where the barrel had been walking around under the barrel nut. I replaced the upper receiver and then also put sleeve retainer in the bore of the new upper receiver and around the outside of the barrel extension. Then installed the barrel into the new upper. That made a huge difference in accuracy with that gun. It went from shooting around 3" groups, to shooting 1/2" groups.

As stated above, there are many possible reasons for the poor accuracy. One that came in a couple of months ago was traced to the gas block being installed canted to one side, causing the gas tube to contact the gas key and put sideways pressure on the BCG. Groups with factory WWB ammo went from 3"+ to less than an inch @ 100. Another thing to keep in mind is that chrome-lined barrels will almost always (not 100%) be less accurate than an unlined barrel, but it depends on the uniformity of the lining job. Also, with a factory HG, if it's got a smaller profile barrel, it will be much more prone to flex due to pressure on the HG than a heavy barrel, so you may try shooting it off of a bag or rest with no additional pressure and see if the groups change. I agree that all of the basics need to be thoroughly checked before replacing parts, but I would highly recommend a free-float tube or HG.
