What's wrong with your AR? Fit's mine fine. I use it because my upper has a lot of rattle. I never knew they claimed to increase accuracy. I was just annoyed with the rattle. +1 on what JonnyVain said. Fits perfect in mine and eliminated the slop between my upper and lower. I too recognize that it is totally cosmetic and not performance enhancing. I think I ordered mine through Brownells. |

You are supposed to shave off a bit of rubber from the accuwedge's "seat" before trying to close the upper / lower together UNLESS you really have a sloppy Joe (my Centurion AR from about 18 years ago comes to mind).
But I don't use an accuwedge, but if you're really really annoyed with your rattle trap, that little gadget would prevent you from having a seizure

The accu wedge is made to fit everything from an M16 to high-shelf AR's. You have to trim it.
I have been happy with the results from mine, even though the accuracy claims are bullshit. It just makes the rifle feel more solid. The only problem is, to fit a high-shelf AR, you have to shave off almost all the base and its impossible to cut it cleanly. |

They don't improve accuracy, they just cut down on rattle. I'm OCD like that. You can get them cheaper. I have a plain black one from Model 1 that didn't cost 2.50. OP - you could trim some off the bottom so it doesn't stick up as much. It looks like your lower's shelf is high. |
That's why I love these forums, you learn somethin new every day!  Well I DID trim my wedge down about 15 minutes ago, despite saying I wouldn't I got it down to about 1/8 I bet and I still didn't have it thin enough to close it (without a vice that is). Seems like a better solution for "High-Shelf" AR's is to use the front O-Ring trick? What are some examples of Low'Shelf rifles? I seem to remember that my issue M4 had a deeper recess in front of the buffer area, am I correct in stating this?
ETA- I am a bit OCD (Thanks USMC) and for purely vanity/just want to know, does the front O-Ring trick clean up the rattle at all. I dont have much, nothing thats not totally normal,but again, the OCD is kickin in. |

Yes the recess on the M4 is deeper (i.e. low shelf), and my CMMG lower is low shelf as well. I need to check my LRB Arms lower, but I'm pretty sure it's low shelf also. What brand is your lower for reference? EDIT: Just checked my LRB Arms and it is low shelf. Also, here is a pic of my CMMG with the untrimmed accuwedge installed...

Am I missing something or doesn't a name like Accuwedge imply that it will improve accuracy? 
I have never seen anything from them claiming it will help shoot smaller groups, I just assumed that it was implied in the name. I bought mine knowing it would not improve accuracy, I did know it would tighten up the upper/lower slop in my mid-length. Is it needed? NO. Does it serve a purpose? Yes, and at a relatively small price. |

My BCM upper was sloppy as hell on my lower. All I wanted was a tighter fit. The accuwedge fit fine on my setup. Same here. All of my uppers fit horribly on my double star lower but OK on my Mega. I have been using the #7 orings on the front lug and it works wonders. I am tired of replacing it so I may get a accuwedge soon. I will probably glue it down just to make sure it stays put. |

True that

Hell, might have to pick one up now.

Quoted: What's a "high shelf" / "low shelf" lower? A copy and paste from this thread: http://www.ar15.com/forums/topic.html?b=3&f=12&t=318113&page=6 High or Low Shelf AR Receivers. Who Makes What? This is a list of companies showing who makes high shelf and who makes low shelf AR-15 lower receivers. This is in reference to RDIAS compatibility. RDIAS is Registered Drop In Auto Sear. A RDIAS can be found for much less than a registered M-16 or other AR-15 compatible registered select fire lower receiver. Here is a link that goes in to depth on the RDIAS- www.quarterbore.com/nfa/dias.html Green = Low shelf: DIAS compatible, shelf behind safety on inside of the receiver is 16mm deep from top of receiver Red = High Shelf: Not DIAS compatible, shelf behind safety on inside of receiver is 14mm deep from top of receiver Aero Precision - high shelf /low shelf Ameetec - low shelf Anvil Arms - low shelf Armalite - high shelf Bushmaster - low shelf Charles Daly - low shelf CMMG - low shelf CMT - high shelf Colt - high shelf also receiver block Double Star - low shelf DPMS - low shelf DSA - high shelf DTI (Del-Ton) - low shelf Essential Arms - high shelf /low shelf Fulton Armory - low shelf LAR - low shelf LMT - high shelf LRB/JV Precision - low shelf Mega - low shelf Olympic Arms - high shelf Rock River Arms - high shelf Smith & Wesson - high shelf Spike's Tactical - Bullet Selector Markings = high shelf –– Fire/Safe Selector Markings = low shelf Stag - high shelf Sun Devil - low shelf Superior Arms - low shelf |

thank you, my Colt came with one from the factory

Quoted: Use an inexpensive o-ring on the front lug. Works perfectly for removing the play between the receivers. Adjust the cross-sectional size to the receiver gap you are dealing with. http://www.hunt101.com/data/500/medium/IMG_6260.jpg Where do you get these O-rings? |

LOL! waste of money |
|
I thought Colts were perfect and didn't require such things.

Lowes, Home depot, autoparts stores ect ect. They are #7 orings. |

Yes takeuptheslop-wedge would have been a marketing disaster. For what it was intended for and used properly it is a neat little piece of marketing genius. Accuwedge sounds great and makes you want to check it out.
I 1st read about them when i was working in the computer controlled injection molding (CCIM) business. They were refered to as a simple solution to a simple problem at a cheap price. If i remember correctly they cost the manufacturer about $7.00 to make 100 units, so about .07 cents each. That was the initial run cost so after you did it for a year or so your cost went down even cheaper. |
