The ACCU Wedg eliminates play between the upper and lower and prevents play from developing in those rifles that don't currently have any perceptible play. 

This is perhaps the least expensive of all the 223 rifle many potential accessories, yet it adds immeasurably to the security and surety of the most basic element of any weapon. Installation is a breeze.

 One needs only proceed through the first step of a normal field stripping in order to install the ACCU-Wedge. 

It fits easily into the slot just below the assembly pin.

The ACCU-Wedge fits between the receiver and the trigger assembly housing and completely eliminates any play and "rattle". you always can cut the bottom a little for make it fit batter for your rifle.

Pack of 10!

    make a cheap gun feal expensive

    Took every bit of play out of the upper and lower, it was pretty much night and day. Even with the action of the BCG to the buffer system it was solid and felt even more smooth than I could have asked for.

    Works perfectly. Idk how someone could have an issue when using this. If you need to shave a bit off then it ia very easy but really it is best to just put as much pressure as is needed to get the receiver pin in through the holes.

    I didn't think it would make a difference I cared about, its worth it I think. Feels a little tighter, less wiggle wiggle

    Wobble from top and bottom gone for good. Just had to trim a little to get the perfect fit!

    Works like it suppose to.

    This product works as it suppose to. The wedge help the gap between the upper and lower of my AR build. I did trim the bottom of one of the wedges just so I can easy remove the rear take down pin. If you choose to not trim a little you may have a hard time taking the rear take down pin out as the wedge locks everything up pretty snug. Works great and no issues after a few hundreds rounds, and if the is a problem, you have three when you order so you are good.

    AR Accu Wedge

    Posted by nick, on 26th Aug 2025

    This simple compressible device when placed in an AR action eliminated the slop due to machining tolerances between manufacturers lower and upper assemblies. It was somewhat difficult to close the action with the "Accu Wedge" in place but that equates to less movement. An inexpensive alternative to replacing either a complete upper or lower assembly.

    If you don't like the movement between your upper and lower, and your lower don't have a set screw, then the accu wedge is for you. I've used them for years. It's a simple product that works and it's very durable. I keep a few on hand and after a year or so I switch it out for a new one. For the price, plus the effectiveness of the product, it's a no brainer. I would/have recommended the accu wedge to those with a need.

    Good idea!

    Posted by Newty, on 26th Aug 2025

    Got a Ruger AR 556 and I couldn't get my upper and lower to close. I tried cutting them down to size and it was just to tight, plus my upper and lower where tight to begin with and really don't need it, might work good on a loose setup. Says 3pk and I got shipped 5 so that's a plus!

    works great

    Posted by massive77, on 26th Aug 2025

    fits great! may need to cut some off the bottom with razor blade to get the upper and lower together with take down pins. shave off little of the rubber at a time till the fitment is to your liking. make upper and lower nice and snug with no play at all once modify it your setup.

    Benji Beedle,

    Posted by Very inexpensive fix on 26th Aug 2025

    These little guys do a great job of getting that tiny bit of play out from between the upper and lower receiver. I don't like rattles and loose fitting parts and these wedges tighten up your AR's enough to make a $500 rifle feel like a $1000 rifle. They do not work on all lower receivers however. It fits milspec aluminum lowers with no problem. Some polymer lowers and upper receivers that have thick lugs have to close of a tolerance. And because of that close tolerance, you probably don't need a wedge anyway.

    DT,

    Posted by Just like accu-wedge on 26th Aug 2025

    Works just like the accu-wedge, better value though. Tightens up the two receiver halves. Definitely worth the few dollars they cost. If you have a little movement, this should take care of it or mostly take care if it.
