    Neat lil wedge

    Posted by AJ on 19th Jul 2024

    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.

    Get rid of that slop

    Posted by Christian Powell on 29th Jan 2024

    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.
