Ok all went together in my Spikes lower awesome, finished it up and grabbed my PSA upper BCM bolt carrier group ect... put the upper & lower together & i noticed theres a little play in the upper/lower is this normal? Would this cure my problems: http://www.joeboboutfitters.com/ERGO_ACCU_Wedge_Fixes_AR_15_Upper_Lower_Slop_p/ergo-4988.htm Thanks in advance. |

Quoted: I dont think your "problem" is really a problem. Every now and then I will get a upper / lower combo that fits nice and snug, but i have never noticed any difference in accuracy. I guess if the slop really bugs you, try it. its five bucks. I just ordered 5pack on ebay for $7.59 with free shipping lol, so i'll give it a shot.  |

I had the same issue with my PSA upper and one of the guys in the 68forums.com suggested I use a cheap O-Ring on the Pivot Lug. Cheaper then an accu wedge and from what I have read in reviews is that sometimes the accu wedge doesnt work or needs trimming. The fitting is now super tight with no wiggle. I grabbed extra and store them in my A2 stock if it breaks.

I have heard you can do,the same thing with foam ear plugs but never bothered |

Yea this is what I’ve been reading, wish i would have read that before i made a ebay order for a 5pack of accu-wedges lol. |

Up and down play is no big deal. You should have seen the loose fitting weapons we had issued in the military.
But if you are a picky bastard like me. I'd just go the o ring fix. Mega lowers have a separate screw in them to tighten this slop up. Is it really necessary? Probably not. But I like that feature. Personally that play bothers me and I try to correct it. The item you linked to looks like it would be more of a hindrance. As it seems like it could interfere with the operation of the selector. If you don't like the play buy yourself a 50 cent o ring |

Now you have me interested in ordering a new lower lol. Thanks in advance. You run a set screw in the same hole as your grip screw. It will push up on the rear lug Trigger to remove Trigger take up. I forget the size. MAHA ETA: after a google search I found they are 1/4-28. ETA2: Enough for life Link You can probably find the at your hardware store as well. ETA3: to correct information. |

I hate to tell a fellow gun owner that he doesn't know what he is talking about, but here I have to. Maybe doesn't know what you are talking about is a little harsh, so lets just say confused. There is NO WAY that the grip screw comes up under the rear lug. The rear lug is at least .625 behind where the grip screw comes up I believe you are confused, with the Grip screw Trigger take up method. Yes the grip screw is 1/4-28 but the hole comes under the rear of the trigger. That's how they take the take-up out of the trigger. You might want to look into this further |

You might want to look into this further I actually got looking at my lower after the post by Mahamotorworks and noticed this as well and was scratching my head at how this would take up the "slop" in the upper/lower lol. |

You can see how far back the rear lug is from the trigger group, which is where the grip screw hole comes in at the rear of the trigger. Bob

Bobhttp://i1292.photobucket.com/albums/b579/CCBPikie/MegaReartakeupscrew.jpg Awesome thank you for the picture Bob, i totally understand now. I see that MEGA lowers come with a screw with a nylon tip to takes up the "slop" if you will. What lower is that, that you're using in the picture? |

Go here, http://www.rainierarms.com/?page=shop/detail&product_id=1745 The 5.56 has the same screw. Bob If you have a drill press you could do it to a standard receiver. You would just have to drill the hole at an angle to hit the lug. |

I doubt it none of my Colts have one. The Mega is the only one that I know of. But I surely don't know everything by a long shot!!
Always glad to pass on what little knowledge I have to othere. We are all here to learn new things and help each other out when we can. Oh, and the o ring thing wotks too. Bob |

No offense taken. I dont know what I was thinking. I must have been reading a lot of thread that day and gotten a couple mixed up. Sorry for the wrong info. MAHA That's great, I'm glad that you aren't mad. There is so much information on this site, that it is very easy to get things mixed up. I hope that we can become friends. I am also glad that you accepted my apologize. Bob |

Apparently, the AR-15 rifle operates just fine with some looseness between the receivers. However, like many others I try to find and fix anything that rattles in my rifles, tight fit is goodness. Accordingly, I bought a couple Accuwedges.
The pros include: cheap at $5, easy to install and it definitely does the job. Furthermore, without the wedge, my charge handle drags on the lower just ahead of the buffer tube. With the wedge installed, the carrier is brought up slightly and seems better aligned with the buffer and its tube. Cons: Sometimes it takes a little trimming of the plastic to get the receivers to close. To remove or insert the rear pin, I have to place the mag well on a hard surface and lean on the top rail. There is no easy way to affix the wedge to the lower, sometimes it falls out when you open up the receivers. The o-ring solution looks interesting. If the receivers are loose at the back, not sure how an o-ring up front will correct it, but its worth a try. - CW |
