So I bought a Magpul MIAD to put on my Government Carbine.
The instructions say not to re-use the original grip retaining screw, but to use the supplied screw that has loctite on it instead. Question: Why is this a big deal? Why can't I just re-use the original grip screw? It seems to fit the MIAD just fine. I'm not crazy about getting loctite in the threads of my lower in case I ever want to change back to the original grip (not likely, but with me you never know). |
|
I think the reason behind this has to do with screw length, apparently with some lowers interference is a possibility.
I used the included screw with the loctite, no problems, even removed it once, never had an issue removing anything with loctite on it anyway. YMMV

| I clean that stuff off with a brass brush before installing them. It just makes it a pain when it bunches up in the threads and it doesn't really "lock tite". I prefer the hex screws, but switched them to the Magpul screws after having a problem with the trigger. On some triggers (not all) it is too long and interferes with the function of the trigger and safety. This was most notable on a trigger that was done by Bill Springfield. The little tack weld on the rear tail of the trigger is just enough to cause a problem with the wrong screw. (Not Bill's fault, it is the wrong screw that was the problem.) |
| Sorry to hijack the thread OP but I too have a question about the MIAD's. I'm annoyed at them, really. EVERY pic I see of all the AR's here on ARFCOM that have MIADs, the grips are nice and flush. As some one who is concerned with the fit and finish of my rifle, as well as it's functionality, I seem to be doing something wrong. I have 3 MIADs: one on an Aero Precision lower and 2 more, each on Stag lowers. ALL three do not meet flush with the receiver. If you hold just the grip in your right hand, looking at it, the upper left edge doesn't meet flush with the rear of the trigger housing. There's a gap there on all three of my lowers and like I said, I don't see any gaps on anyone else's. What am I doing wrong? |

Most of the time it's just the plastic being a *really* tight fit and you just need to manhandle it a bit. |

I have two MIADs and I had to remove material from the inside of the backstrap(in the curved area) on both to make them fit. |

Most of the time it's just the plastic being a *really* tight fit and you just need to manhandle it a bit. Get your Girlfriend's/Wife's/Moms/or buy a hair dryer. Blast some hot air on the grip until it gets hot then try pushing it on. It will help loosen up the plastic a little. |
| When I used the RRA bolt it was too long so I used a small washer to keep it from bottoming out. I guess I could have cut it down but used a washer. Also, I did have to take a fille to the rear curved part of the grip in order to get it to sit flush. I have read that this is a problem with these grips, but once you have it installed right they look great. |
| I've been eyeballing my own (first) MIAD, and the shorter screw, along with the thinner top web of the part, is to allow you to put the bolt/3 rounds/etc. in the core. Using any cap screw, for example, would take up too much space and keep you from putting in a core with anything in it. |

YMMV This I have had too long of a screw hit the bottom of the trigger assy and jam it up or prevent the weapon from coming off safe. |

I used a combination of files to sculpt the backstrap. I think that this is odd, because I have magpul everything, and every other part of theirs that I have has out-effing-standing fit and function.

Same experience here. Just used my mini file fit to trim it up. |

The primary reason is the supplied screw with the MIAD is compatable with all cores. The standard screw will not funtion with the CR123 and the AA cores. The head of the screw will impact the top of the cores not allowing them seat. The lower profile MIAD screw does not interfere with either of the cores.
So you don't use the aforementioned cores, I suggest using the supplied screw. If you don't want the lock tite on there, remove with heat and a wire brush or razor. |

Hmmm I re-used the original screw and I have a AA grip core and it seats fine. |

Some clarification:
Both the MIAD and MOE Grips use a 1/4-28x3/4" slotted pan-head machine screw with a self-locking Nylok® Blue Patch™ (link). We went with this head style to afford some extra space for the accessory cores and to maintain mil-specs with the use of a common screwdriver for installation (the military does not like to use socket cap screws on its guns). Also, the 3/4" length is what's required for the internal dimensions of our grips. OEM mounting screws are generally too long and can protrude into the interior of the receiver potentially interfering with the trigger/safety group. FYI the Nylok® patch can sometimes cause quite a bit of resistance during installation depending on the class of the tap that was used on the lower, thickness of the anodizing, etc. Some gentle heating of the patch or scraping with a wire brush will solve this problem if it becomes apparent. Regarding the backstraps, our B2 and B3 backstraps do fit well with most receivers on the market. However, the spot they mate with on the lower is not considered a 'critical-tolerance' area by most manufacturers and it may be necessary to do some trimming for best fit. Edited to add: For those that are having issues with the MIAD not seating all the way forward and leaving a gap at the front, usually this is due to the issue mentioned above with the 'beavertail' on the B2 or B3 backstrap not interfacing well with a particular lower. Remove the backstrap to properly seat the grip and then reinstall the strap with some possible trimming to match the tolerances of the receiver. |
