I'm pretty sure you just answered your own question.

if your upper and lower receiver are loose and rattle a lot they will quiet the rattle. if they already fit together good their is no need for the rubber wedgie.

I don't see the point anyway. I don't think it effects the accuracy of the rifle if theres a little wobble.

Seeing as how the barrel, bolt/carrier, and optics are all built into the upper, probably not much. However, the same goes for bolt guns, yet glass bedding stock is supposed to help. I think the wedge falls under the same concept. Increase rigidity and reduce wobble in the platform to improve accuracy (actually, the proper term would be precision, or the ability of the rifle to consistently make shots with little variation). |

My Colt HBAR CNMT came with one. I put them in if there is any play between receivers but that's just because I like the more solid feel they give the rifle. I don't think they help accuracy unless your receiver fit is so bad that the cheek weld changes slightly?

They are also said to prevent tight fitting receivers from loosening by reducing the enlarging of the take-down pin hole caused by firing and impacts. Many older ARs get loose from this type of wear. The Accuwedge may do this, but it would take a long study to prove it.

Make the fit tighter. They do work I have them in all my guns.

They'll make your gun more accurate... Hence the name....

Hmmmmmm.......doubtful. The wobble and slop is mostly psychological. |

I've had them in a couple of Colts. My S&W MP15T and my Armalite don't need them.

Russ... Run a diagnostic check on your "sarcasm" meter... I think it's out of calibration......

Don't worry Harv, I understand your intent. Perhaps if the guy puts in two AW's the rifle will be twice as accurate. |

In case any reader is unfamiliar with these things, here is one installed.

So does it push on the takedown pin, or does it push against the BCG?
If it pushes against the BCG, wouldn't it wear out pretty quickly? |

Excellent pic friend! I think it's more of a feel good device. If you have some slop, it's not required. if you have lots of slop, it can't hurt but it may or may not help anything. It's your thing (and your money) do what you wanna do. Danny

Thanks! A friend gave me a few of them, so I tried them. I can't prove it did any good, but it didn't hurt any. |

They push against the upper receiver take down pin lug. |

Bah. Those are the words I was looking for when I put in pin.
Okay then. |

My own AR is pretty tight, so I've never had any reason to install one. But it seems to me that if there is slop between the upper and lower of your rifle, it CAN affect accuracy. If the slop is one direction while 'relaxed' (i.e., just before you fire), then the recoil of the upper against the lower will introduce a little bit of movement as the gun is firing... resulting in some barrel misalignment. All this takes place in a fraction of a second so it isn't real obvious. But what would any of us do to gain, say, 1/2 MOA of accuracy? This question is NOT academic; there are several factors that will affect accuracy. If you have a potentially perfect rifle, capable of firing one-hole groups at 100 yards, but have 5 error factors that each introduce 1/2 MOA of inaccuracy, then your rifle won't shoot better than 2 1/2 inches at 100 yards. This is called "cumulative error." You must eliminate ALL these errors in order to shoot that perfect score. |

While I am inclined to agree with you, Armalite's testing appears to show that a little wobble isn't a problem. Maybe they weren't going for that one-hole group. Either way, since the wedge is so cheap, I wouldn't criticize anyone for buying one. |

Don’t forget the Army Markmanship Unit's thoughts too. I think those fellas might know a thing or two about accuracy. |
