Most Helpful Positive Review Does what it's designed to do
The wedge does the job. The upper and lower are much tighter now. They're basically the exact same thing as the more expensive brand, so save some money and pick these up. Just be sure to shave it down to size.
Most Helpful Negative Review Useless. Chinese
This item was not as described and when I figured out where it goes, it did not take the tiny bit of wobble out of the fit between upper and lower. Brownells has the directions and theirs is more, but made in the USA.

Nice and snug

by me, Verified Owner from IN, United States Written on September 25, 2026
If you have a lot of wiggle between your upper and lower this will fix the problem. For sure. I added several to a recent order cause they're not expensive and having a few laying around is a good thing.

Perform as expected

by Craig Nap, Verified Owner from FL, United States Written on September 8, 2026
If you AR has an upper and lower receiver wobble, this rubber wedge will eliminate the wobble. Good quality receiver sets and high quality AR's do not have wobbe.

DEPENDS on the AR make.

by AF, Verified Owner from SC, United States Written on July 11, 2026
This will not work in every AR made. I put the receiver wedge in 3 different AR's and had 3 different results with the upper having a snugger or looser fit. It's inexpensive so take a chance.

Creates no-rattle joint between ar-15 upper and lower

by scrlck, Verified Owner from VA, United States Written on April 25, 2026
Similar in principle to an Aero Precision lower with the no-rattle adjustment bolt in the grip compartment.
Both the Aero lower and this wedge presses plastic into the underside of the rear take-down mount, thus creating a tight fit between upper and lower, which eliminates rattle after adjustment.
Works as expected, but may require some trimming of this plastic spacer, while the Aero lower has an adjustable bolt with a plastic tip so no trimming required on that, but same result.
Pros:
  • no rattle between AR-15 upper & lower
Cons:
  • trimming may be required
Best Used for:
  • AR-15 when upper and lower do not fit without rattle
Would recommend: Yes

Works Great

by Mike, Verified Owner from FL, United States Written on April 23, 2026
I was skeptical at first, like how this suppose to help upper and lower slop. Bought a few and installed them and I am highly impressed.

Pros:
  • does what is promised
Cons:
  • No
Best Used for:
  • stopping the wiggle and jiggle
Would recommend: Yes
