The quickest, easiest, and least expensive accuracy-upgrade you’ll ever find for your AR15!

    I had a loose rear take down pin in one of my ARs and this little inexpensive wedge fixed it right up.

    It works!

    So I have an upper from a different manufacturer than the lower and had a little more play than I could find acceptable. In fact, it rattled. I ordered and installed the Accu-Wedge and it tightened up the action and no more rattling. Will it fix your problem? It doesn't cost much to find out. I ordered 5 so that I would have spares and maybe help out a friend with a similar problem. It installs in seconds underneath the take-down pin.

    Perfect accessory for your loose fitting receivers. Easy to install and very affordable. Fast shipping and in stock like most of there products. Arms unlimited is one of the first places I look when needing any parts for my AR’s.

    The easiest upgrade you can do...

    Just buy it and drop it in - it's that easy. It takes up any slop between your upper and lower, making it feel solid. Simple solutions are the best!
