    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.

    It also works great in my LR308 DPMS Gen1. So simple yet so effective.

    They do exactly what they were made to do. Takes out all play between upper and lower receivers. Definitely worth the money.
