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!

    AR build essential

    Posted by LNO, on 25th Aug 2025

    These shims virtually eliminate any loose upper/lower slack and rattles. They are very easy to install and seem to last forever, although a bag contains five. Even though AR parts from good companies are generally precise in measurements, it is inevitable there will be some permissible tolerances and these plugs simply reduce the annoying consequences.

    accu wedge

    Posted by JDUB on 25th Aug 2025

    If you are unfamiliar with this product the accu wedge is used to eliminate play between upper and lower receivers of AR-15's. These are a useful solution to less than perfect fit of recievers. I would recommend the product if you have any play between your upper and lower.

    Worked Perfectly

    Posted by GunKnightSwift, on 25th Aug 2025

    These worked perfectly to remove the slop between my upper an lower. Keep in mind that they need to be filed down (I used a dremel) to fit your receivers. They are made with extra material on the bottom to be removed so they will fit any receiver.

    Do what they need to

    Posted by BeepBoop, on 25th Aug 2025

    I've used these for several builds. They work exactly as they should and take the wiggle out of the receiver. Requires a bit of fitting but they are very useful once you have them cut down to size. Highly recommended.

    Just what I needed

    Posted by Jahrid on 23rd Jun 2025

    Get the slop out of my spikes AR-15 upper-to-lower, wish I could’ve gotten a few more.. (orders limited 1 per customer) Makes it a little harder to close the rear takedown pin so if you can’t get it closed maybe try sanding down the bottom a little bit if you run into the same issue.

    Tight

    Very tight fit. I think the wedge is better than the nylon tipped set screw.

    Surprisingly Excellent

    Posted by James on 23rd Jun 2025

    Had a little side to side slop between an upper and a lower that I felt a nylon screw wouldn't help. Placing this in the lower produced a very tight lockup and eliminated any play between the upper and lower. This is an excellent product.

    They work...

    Posted by A. Magno on 18th Jul 2020

    These little things are an inexpensive upgrade that doesn't require any modification to your rifle. It removes any slop between the upper and lower receiver of your AR15. The claim is by doing this the rifle's accuracy will increase. I've owned ARs with tolerance differences between the upper and lower in the past and I never really worried too much about it. But after I saw a video demonstrating how the accuracy increased, albeit a small percentage, I figured using them wouldn't hurt. Well long story short I have them in all my ARs now. I do like that my ARs now feel like one solid rifle versus two halves that wiggle here and there. One caveat though, it will probably require you to remove some material from the base of the wedge to get a custom fit. So have some sandpaper or a small grinding tool handy. You don't want the wedge to make it too difficult to push the disassembly pin in and out. You're looking for a snug but manageable fit.
