AU Accu-Wedge for AR15/M4/M16 Rifles

Works as advertised to tighten up any slop between the upper and lower receiver

The AU ACCU-WEDGE is a neat little addition for any M16/M4/AR15, as the wedge mitigates most reciever wobble, although this is intended to fit in uppers and lowers that have "wiggle room", I own a S&W sport 2 and attempted to install one of wedges only to find out that the reciever has nowhere near enough room to reassemble. No big deal, as its very affordable and the other two fit very well in my other AR15s. Would recommend at least one.

Works well

Simple and solid fix, no more wiggle.

Easiest, fastest and cheapest way to get rid of any wiggle between your upper and lower.

Works like a charm. You may need to sand the bottom worst case but holds up nice and definitely make the feel of the lower and upper feel nice and tight.

Had to buy a few of these over the years to tighten up the slop between upper and lower recievers. A necessary item if you can't stand sloppy tolerances and your lower doesn't have the tensioning screw. Can be fitted by sanding the base of the Accu-Wedge for a perfect fit. I always keep a couple of extras for friends as well. A must have for your "extras" parts box.

Does exactly what it is intended to do take up slack and works great

Great product to to lock up tight the upper receiver to the lower.
