Upper/lower wiggle

[under9]

Is there anything you can do about some wiggle between upper and lower?It really doesn't brother me but if there is a fix I would like to look in to it?

"Accuwedge"

Oh, and before you start trying to trim material to make it fit, turn it the other way.

There is really nothing to fix and a certain amount if "play" is a good thing.

Is it worth buying. Its not bad I was just wondering if you could do something about it.

[MisterWilson]

At $5 it's not bad.

Leave it alone.

This is your first AR, right? At first, the wiggle may seem annoying, but once you start shooting ARs a lot you won't even notice it anymore. As Grant said, a little "play" between the upper and lower is a good thing, and it's part of the design. I've seen some ARs that were very tight, or that guys jammed Accuwedges in, and once the gun heated up from a decent bit of firing they could be a real PITA to get apart if you had a problem. Also, if anything goes wrong and that Accuwedge gets damaged or chewed up, you can get wonderful little bits of red rubber or whatever down inside your lower that could potentially work themselves into the trigger and hammer area and screw things up big time. I actually saw that happen once.

That's my advice. :)

Leave it alone and just shoot the shit out of it.

Only problem I see is pressing the lower and upper away from each other. This could cause pre-mature wear.

I'd also be worried of the wedge coming loose and locking up the trigger mechanisms. Just like a primer falling into the lower.

I used an accuwedge once on a large pin upper to small pin lower. I also had a pin offset adapter. Any normal amount of play would not worry me enough to use something that could potentially down the rifle.

Do yourself a favor and leave the rifle as is. I have been working on these guns since the 80's as a department armorer and they are just not needed. It has already been pointed out that they could potentially cause issues down the road.

If it bothers you that much, go to Ace Hardware or Home Depot and buy a #7 o-ring for 20 cents. Take your upper off your lower. Put the O-ring around your front lug on the upper. Put them back together. It will tighten it up.

Don't worry. Best M16/ARs that I have shot wiggled around like Hula dancers on speed.

I have a M&P 15T And it seems to have substantially more play between the upper and lower than some of the other rifles I've seen. Do the eyelets give out on the upper after substantial shooting i.e. from battering of the upper moving against these pins during recoil or rough handling of the weapon?
