Accuwedge....Worth it?

Haven't shot mine since I installed it. But took out all the [slop] between the upper & lower. My fatgirl is mighty tight now /ubbthreads/images/graemlins/cool.gif . I suspect, it will help tighten my groups some. I'll ask this yrs coyote's, their opinion /ubbthreads/images/graemlins/laugh.gif
 
The "slop" between the upper and lower receiver is very annoying, but not a cause for inaccuracy. That being said, I used a similar product. I just don't like the feel of any "wiggle" while I'm handling an AR.
 
I use an old foam earplug under the rear lug.

It compresses when you pin the upper and lower together and does the same thing as a 4 or 5 dollar piece of rubber, very cheap I am.

You guy's have me wondering, now. Why an AR, will not shoot tighter if the [slop] is gone? Please explain, so I'll understand. Thanks.
 
I have used the accuwedge in every AR that I have owned, until I recently got an AR built on a Rock River Upper and lower and they fit together so perfectly that I did not need one. Made a believer out of me and I will not use anything else in the future. You can say there is no difference in stripped uppers and lowers if you want, but I now own both and there is a big difference. Feeling is believing.

It makes intuitive sense that any slop would cause innaccuracy, but it doesn't. I can't explain it, but years of NM competition has pretty much proven it to be fact.
 
Your accuracy is dependent on the fit of the barrel, barrel nut, bolt and bolt carrier, and of course, the shooter.

If you could remove the upper, lock it in a holder like a Ransom Rest, and activate the firing pin without the lower, you would still have the same degree of accuracy.

Any looseness in the fit between the upper and lower is just an annoyance. I've installed the accu-wedge in a couple of mine that have a lot of 'slop' and I have two that fit tight enough that it's not noticeable.

All parts regarding accuracy (bolt & barrel) are in the upper half. The only interaction between the upper and lower at the time a round is fired is the hammer in the lower striking the firing pin.

I still run an accuwedge in my Colt BC the slop was in excess. They ought to call them slop-wedges. As others have said, foam earplugs work just as well. Just don't look for tighter groups from one.
 
Never had a need for one on my RRA rifle. It fit snug & still does. I've put close to 1k rounds through the rifle & there is no slop. Tight as a mouse's ear. /ubbthreads/images/graemlins/grin.gif

We have one in each of ours. I find it interesting in that without, wouldn't this be like having a loose action to stock fit??? The upper is floating around somewhere as the bullet is traveling the barrel, if this is exactly the same each firing then no accuracy change but if the floating or movement is different shouldn't this change point of impact an amount. I know this is rally evident in rimfire even with a well set up Br gun held differently shot to shot.

Intuitively you would think so, but years of competition experience has proven it to be otherwise.

They are cheap though, so why not not use one if you don't already have a tight fit?
 
Everything I have ever read on the subject says the accu wedge is a fix for a non existent problem. It can take some slop out of the fit between the upper and lower, but has absolutely no effect on accuracy.
 
I have only ever needed them for my Bushmasters. Like the other's say its only purpose is to keep it "quiet". I have never needed them on my RRA's or DPMS's. Just my opinion and experience with them.
