how to take the wiggle out between AR upper and lower ?

Accuwedge was made for low shelf AR`s without full auto parts to take up the slack. Its supposed to fit without trimming if you need to trim it then you didnt need it.

I dont care what you do but some people talk out their ass and then get pissy when called on it....... Use two accuwedges one for the AR and the other for your personal pleasure. :)

Wouldn't a loose fit between the upper and lower be simular to loose bedding in a R700, M14 or other rifle??

Not really, the lower doesn't exert any pressure on the barrel and the sights are attached to the upper, the lower is basically hanging off the bottom, the relationships between a traditional rifle lock, stock and barrel don't have any parallels in all metal rifles.
 
The play is annoying though. Its hard to believe that as I stabilize the rifle with the stock and pistol grip that are part of the lower, and the upper is free to flop about and maybe move as the hammer is, that it can't contribute to inaccuracy. Why wouldn't a loose upper to lower be like any other poorly bedded rifle?

The Accu-wedge is nothing but a gimmick,play between the upper and lower has no effect on accuracy or function. Anything that wedges the uppers together will cause excessive wear on the receiver, as the pivot pins are forced upwards. This will cause the "holes" to oval increasing the wobble.

Because the round is chambered solely in the upper, the barrel is fixed solely to the upper and the sighting devices (RDS, irons, scope) are fixed to the upper, none of that moves at all.

The only reason a wiggly lower will affect accuracy at all has to do with the operator of the gun, and not the gun itself. ;)

That being said, I have an Accuwedge in my AR, more for some psychological benefit to me that anything else.
 
My understanding is "ultimate" accuracy has more to do with just the scope, barrel and chamber. The shoulder, trigger finger/hand and stance are all involved. Not just the gun but the interaction of the gun and shooter right down to his/her feet and into the ground.

Some bench rest guys put baby powder on their rests so the rifle goes straight back as consistantly as possible. It seems to me depending on how the AR is sitting it will somtimes flop left or flop right in that split second after the trigger is pulled and before the bullet leaves the barrel.

This is probably a little overkill for the AR however.

I have hear this many times and I personally have a hard time believing that a loose fit dosn't affect accuracy, but I am NO expert.

I also heard that the accuwedge dosn't provide enough fit between the upper and lower. You need that JP Ent pin or more drastic measures.

Again if you need to trim the accu wedge to make it fit then you didnt need it in the first place. Get it?

It must be hard for you to accept the truth.

Don't know where you're going with this... your mind is made up about the accuwedge and I respect that. But don't try to tell me what I need or don't, that's not the point of this thread.

I don't see how a wobbling upper is "an imaginary problem"... Well some don't see it a "problem", but me, I don't like it.

Its imaginary in the belief that removing said wobble will do anything other than ease ones mind. Its a gimmick plain and simple. The AR is a combat rifle, not an olympic shooter.

You said it, it eases my mind. I don't know many things that cost 3 bucks and that can ease one's mind! ;)

Anyway I said what I had to say about the accuwedge. I'm out of here.
 
If you're seating the rifle firmly and focusing on the fundamentals of marksmanship you shouldn't feel/notice the wobble. Add to that the logic that such devices are a waste of money no matter how little they cost. Call me crazy but all accessories must fit one of two criteria before I'd waste my money on them. The accuwedge(inappropriately named by the way) doesn't fit either.

The thing to put in perspective is that alot of folks take knowledge learned about accuracy from (primarily) bolt guns and try to impart that same logic with an AR.
It doesn't quite work that way, and there is substantial information and documented cases of what does and doesn't work, by very knowledgeble individuals that have deen doing it for a very long time to back it up.
The USAMU along with a vast number of US NRA High Power shooters have spent more time, money and energy than any one out there on trying to improve the ways in which they (ARs) shoot. Read up on what some of the early pioneers have to say about the accuwedge -or any other 'accuracy tips'. Once you've done that, try actually replicating their findings to prove or disprove them for yourself as (some) others here have done.

Even if it doesn't do anything for the mechanical accuarcy of the rifle, it may improve your shooting by way of instilled confidence, hold -whatever. If that floats your boat then go for it.

What slack would the auto sear be taking up?

The dude's talking outta his ass. All C7s/C8s have play between the recievers. You will very rarely find one without. The full auto sear has nothing to do with it, as there is no way it can interfer with the take down pins or frame edge of the recievers.

Another genius... you know what a low step AR is? Know what a DIAS is?
When you figure it out you'll see when a acucrap wedge is needed .

A DIAS is not an original design spec. Anything after market or "after thought" is a crap shoot and does not justify additional after market crap.
