Is it OK to have or not to have a wobble play between the upper n lower receiver? The LWRC I got has more then I prefer. My 6.8 and first ar I built doesn't have any. And they don't have take up screws or accu wedges. But I did put in a accu wege on it and it seemed to locked it down nice n tight..

So is it personal preference or a bad thing to have when want better accuracy?

I always heard that it made little or no difference in accuracy. But personally, I can't imagine how it could NOT be at least slightly detrimental to your accuracy. Granted the sights and barrel are not affected at all by that wiggle, but if it wiggles as you pull the trigger, I don't see how it would not affect your accuracy to some degree.

I know that it bothers me when I shoot a gun with the wiggle factor. So maybe the gun is just as accurate, but I'm not....

i guess depending on how bad it is, is the wobble movement or just gap? i could see problems if it moved around when putting pressure against your shoulder too much i guess or pulling trigger.

It's movement. I can put a hand on both and move them. The gap I understand stand cuz they are not a mated set.

I qualified expert in bootcamp, I could put about 20 pages of my green monster in the gap between the upper and lower. Did it make me uneasy, yep, effect accuracy? Not by minute of man.

With 3moa rated ammo? I think the op was leaning more towards MOA or better precision.

I don't know if this is right or not, but what I've always thought was that zero play is what you want. From the time that the firing pin strikes the primer until the projectile leaves the muzzle you want minimum movement. Think about the emphasis that is put on soft cycling and not over gassing a rifle. In my mind, a loose fitting upper to lower would allow for small variations in the POI due to slight changes in the shifting of the POA by the upper moving while the round is traveling down the barrel. Hopefully an AR guru can give more insight.

I put one of those rubber bumper devices in that stops all the wiggle.

Accu-Wedge. It will stop the rattle, not sure it will have any effect on accuracy, but it can't hurt.

Or do what i do, stuff a foam earplug in there. It will conform on its own where the wedge may need trimming.
And I'm cheap.
