Pack of 10! AR15 Accu Wedge Anti-Wobble Upper/Lower Receiver Tightener 5.56 .223

Great product! Pros: Locks ARs up tight Cons: none

The Accu-Wedge does not "eliminate" play between AR uppers and lowers (depending on the severity) nor is it a drop in modification. I had to trim the part in order to get it to work in an M&P 15. The play between the upper and lower has been reduced, but assembly and takedown require a lot of effort and care, meaning physical strength, ensuring that the wedge is properly in place, and more importantly, time: It takes at least a minute to reassemble the rifle. *Bottom line: it's a good fix for recreational shooters, if your safety/life may depend on your rifle, take a pass. Pros: Reduces "slop" Cons: Requires modification, relatively expensive

These are must haves when building your on AR Platform rifles. I'd been looking at all the gun parts vendors and all these items were backordered for ever! Thanks Optics Plantet for keeping much needed parts/items in stock!! Pros: Optics Planet has this item in stock when others had it on backorder! Cons: Shipping was a little slow.

Pros: really like it for what it is for

Works well as a recoil buffer. Does not tighten receivers, receivers can still twist side to side so the play remains. Pros: Easy To Install Cons: Does Not Tighten Rock Solid

I bought the Accu-Wedge after reading an article on ways to improve your shot grouping. I had never considered the fit between the upper and lower to be an issue. I did check out the fit between the two and found there was a bit of a rattle prior to installing the Accu-Wedge. Now there's just no more room and it's a tight fit. Installation by the way was very simple. Remove a pin, slip in the Accu-Wedge, put the pin back in place. I will be taking my AR-15 to the range soon to see for my self if my groupings become tighter.

I wanted to eliminate the wobble in my very top heavy PSA AR15 18' heavy. I thought the accu-wedge would fix it, but out of the box the accu-wedge was a quarter of an inch too tall for my PSA AR 15 upper and lower receiver set. I ended up spending too much time fitting the accu-wedge to my PSA receiver. Once I fitted the accu-wedge it did not completely eliminate, but reduced receiver wobble. My only advice is to expect to custom fit the accu-wedge to you receiver combo, when you do; take your time and incrementally take off material.

Installation was quick and very easy. Works as advertised and completely eliminates any play between the upper and lower AR15 receivers.The gun "feels" better once installed. It does make the operation of the takedown pins more difficult.

I bought this to rake out the rattle between my upper and lower. This will not eliminate all of the play nor make it a match-grade fit, but does make a notable improvement in the feel. As one would expect, it makes the rear takedown pin a bit more difficult to remove, but not too bad. In short, the upper/lower will still have some play in rocking back and forth, but no rattle. If you want to completely eliminate the play, get the JP Tension Pins.....10 times as expensive, and you need tools to remove, but they take out 100$ of the slop.

This is a must have for any AR platform rifle. It's extremely easy to install, check out all of the install videos on youtube. It's really amazing that such an inexpensive purchase can have such a big affect on the rifle, it now feels more solid, and 'not cheap.' I highly recommend buying several of these pieces.

Actually tightened up my Right To Bear upper to my Colt lower nicely. Easy to trim if needed like mine did. Highly recommend. Am definitely getting a 5 pack for each of my builds I have coming up. A+!

This little guy does just what hes supposed to do. I have an anderson upper and lower and while snug there is a tiny bit of play in the connection. I dropped this guy in and it completely elliminated the play. The only issue I have is that I could previously remove the receiver ping with my fingers but with this guy installed it requires tools.
