I am trying to install a Magpull grip kit on my new AR receiver and for some reason I can't get it tight! I installed it the other day and it felt good but after a day shooting it got loose and had a little play. I am using the grip attachment that has the built in trigger guard. It seems to me that because of the loctite on the screw im not able to drive the screw it far enough? Also am I supposed to use the MIL SPEC lock nut on the bolt? I am using the bolt that came with the magpull grip and NOT the stag one that came in my LPK. I am wondering if I need to use the lock nut that came with the LPK? The bolt is pretty tight and it's still loose. I am not using a wrench just hand tight with a screw driver.

funny, I just had the same problem last week. The thread locker compound is preventing you from completely tightening down the screw. I noticed mine was stopping there, so I ran the screw through a thread die a few times to cut to locktite. Probably could use the nut from the kit though.

Do you mean the pistol grip lock washer? I have 2 magpul grips and i believe I used that washer in the LPK with the screw supplied by magpul and both grips are on there just fine. It wouldn't hurt to try it out. give it a shot and let us know if that worked out for you.

Does the Magpul screw have a red-tipped end? (mini-gasket)

I had issues with my Magpul screw - it wouldn't go in all the way because of the locktite on the end of the screw. It felt tight, but when I went to shoot it it came loose. Try the screw that came with the Stag parts kit and see if that helps

Yah, the screw magpull supplies has a bunch of blue locktite. It's VERY hard to screw the screw in passed the loctite. Should i try and scrape the loctite off?

YES i am referring to the pistol grip washer that was supplied with the LP. Should I use it?. The magpull instructions show it not being used.

I had a similar problem with my MOE grip, after closely looking at my grip screw it seems that they didnt cut the threads perfectly straight. I suggest you email
jbeard@magpul.com

I had the same problem yesterday when I put on my MIAD. Just kept playing with it and it finally went.

Wow, that royally sucks! The steel screw will strip/warp the threads in the aluminum receiver for sure! Too bad I already installed mine--I thought it was the blue loctite and didn't check the threads on the screw itself...

I had the same problem as well. I just used the screw from the LPK. That worked fine.

It is difficult, but not impossible to screw all the way down. It screws in much further than it seems to need to, but once it bottoms out it will me nice and tight.

Hey chee. should I use the pistol grip lock nut when using the standard screw that came with the LPK?

Yeah, I had the same problem with one of my personal MOE grips.

I just changed the grip screw myself, but your suggestion to contact magpul to help resolve the issue is a really good one.

The standard screw in the LPK is a lot longer than the screw supplied. I don't know what to do here. I don't want to try and crank the magpull screw down, i don't want to damage my receiver.

BlackonBlack,

You mean the washer? Yes, use the washer with the standard screw from the LPK. You should be fine. Good luck.
