Will Work If There's Alot of Play

by -

First: I bought this for my S&W M&P15 Sport 2 rifle because there is some play in between my lower & upper receivers. To get this to fit I ended up having to cut off 80% of the wedge to get it to fit. <br>Second: Once I had this installed it did indeed make my upper right but the movement that was there before was still there and even after I removed the wedge it still had about the same amount of play as it did with the wedge in. I can see this working on a build that has a huge amount of play but if your like me and only have a small amount of play then I wouldn't waste the $.

alter tis spacer until it fits

by

I see complaints about it not fitting certain firearms. I've found that all I needed to do was carefully trim the spacer until it fit.

Don't purchase if you have a Palmetto State Armory AR10

by -

This item will not fit a PSA PA-10 (AR-10).
<br>
<br>The item itself is nice and a great concept, but unfortunately it will not fit my firearm.

Works!

by

Simple part that did exactly what it's intended to do. Didn't have much slop to begin with in my PSA build and this eliminated that little bit it did have. Worth it!

I’ll never have an AR without these.

First: I think the people who are shaving these down are using them wrong. These are made to work by applying pressure against the upper, from the lower, which reduces/removes the slop and play between the two. If you shave them down, they’re not working right anymore...
<br>
<br>I’ve put these in two ARs, and I had to apply a decent amount of force to squeeze the upper and lower together and get the takedown pin slid back into place. It’s supposed to be that way, otherwise it’s not doing its job. There’s a little bit of break-in on them too, which makes things easier after sitting closed for a while.
<br>
<br>With a really sloppy upper/lower matching, these will make them feel like a top of the line setup with almost no detectable play. If you have a high quality upper/lower matching, the play will simply be gone, and it will be solid as a rock. I’ve never felt a stock setup that was as solid as these things make it feel.

For low shelf lowers

by -

Worked great. Just needed to trim a small amount off the bottom of it. Dropped it in and no more play. The reviews of some people saying they have to trim a lot off and ended up messing it up. May have a high shelf lower and than you will have to be careful trimming it to fit. If you have a low shelf lower and you are trimming it down to paper thin you don't need this wedge. That is a small amount of play that is normal. Primary shipped fast could not be happier.

May not help everyone but it is cheap insurance

First let me say that as usual PA customer service is 1st rate. Ordered late on Labor day and forgot an item I wanted so I called Tues to add it to my order. Tony took care of it and the package was on my door step Thur morning. Outstanding!!! Thanks Tony!
<br>
<br>The Accu-Wedge dropped into my DPMS lower without having to trim at all. The "slack" between upper & lower is completely gone though I now have to squeeze the upper & lower together to install or remove the take down pin. A non-scientific before & after test at the range showed some improvement to group size after install.

Not the same as kleenbore I used to know....not worth five bucks !

by -

I’ve bought the kleenbore brand before, and this isn’t it, they were worth 5 bucks , because of the material they were made out of trimming was not necessary, for this to work it needed to be trimmed it is a harder material , which is not worth five dollars because I have also bought a different brand for a buck apiece , this is what I compare this product to, apparently they have made a change of material , it works just as well as UTG brand , trim to fit , the original material compressed to the Application !

Well worth it.

I built a ghost upper on an aero lower and had a bad fit. Lots of wobble. And the bolt carrier would hang up on the buffer tube. And not rack the action. This little wedge fixed all the wobble and alignment issues.

Save your money

Waste of time and money took none of the play out

Great product

by -

Super tight! Just the way I like it.

Removed all slop from my PSA upper and lower

by -

just like the title says. worked great. if you are anal like me and can't stand a wiggly upper and lower this is worth every penny.

Almost perfect

by

This little gizmo works just fine. If you're a little doubtful I recommend that you chance it as it's so cheap you can't go wrong. I have a mil-spec armalite DEF15 and I did have to trim the wedge down... HINT: Trim small amounts from the bottom. Once I got it to the right size (a little higher still so that it required an extra little squeeze down on the upper) it removed the play and didn't pop out or move at all when taking the AR apart.

Great service

by

horrible productThis was my first purchase (a Magpul Fixed Carbine stock and this turkey) from Primary Arms and the stock and PA's service were great. However I had the same experience as some others: I had to trim so much off the wedge that there was almost nothing left and I still couldn't get the upper attached. I ended up using some heavy duty 3M tape made for hanging stuff on walls. It worked like a charm: The stock and the tape made everything rock solid.

Helps keep upper and lower tight.

Simple and useful. It took out the tiny bit of play I had. Now I can stop obsessing over a little thing and enjoy my rifle.

This is a great piece to tighten the upper on lower, if it bugs you. I tried different takedown pins with mild success. This was perfect.Takes seconds to install. Did shave a touch off the bottom. Will use them in the future if needed.

Good product if you have a little play between your upper and lower receivers. Easy installation, and only minor fitment. Really helped out my SBR! Works very well. Fast shipping as always Primary Arms

It worked!

Went in without issue, really tightened the receiver and upper mating!

accu wedge

Very simple product and does as advertised. I didn't need to shave any of the plastic off but I have heard that others have. Makes for a tight fit with no wobble between the recievers. I like this products simplicity and effectiveness.

Buffer tightens up fit between upper and lower

by

This buffer took all the slack and movement between the upper and lower of my AR. Works great!

Good piece

by

Nice addition to my rifle

Accu wedge

Good product to keep receivers from rattling. Probably won't do much for accuracy because it will still allow flex

FAST SHIPPING, EASY TO INSTALL, I DID NOT HAVE TO TRIM TO FIT, AND THIS FIXED MY SIDE TO SIDE PLAY,
