So i got 2 lower build kits, neither has a washer for the grip in it. so i put one together and the grip is loose due to the missing washer i assume. does anyone know where to get this washer or have any extras they could spare? I dont want to deal with their customer service since its horrible and ill probably have to wait a month.

I would think just take the screw out and go to lowes, match it up to the right size washer and you would be good to go.  

bingo......I also don't use washers in all of mine and never had a problem

I don't use washers with anything but a GI grip. Even then you can get away without it. Use a single drop of BLUE Loctite on the bolt and you should be fine.

Pretty sure its 1/4. Very common size any hardware place has them

I don't have a washer on mine.  Like someone else said, just a drop of blue loctite.

Deff need some kind of washer unless i did something wrong, it is my first build. screw feels tight as itll go. i can pull and wiggle the grip around, and has alot of play. i have washers at work i can snag and try, wasnt sure if i needed a special one.

Its a magpul moe grip if it matters

It's a star lock washer for the 1/4-20 bolt

Pretty common piece of hardware

magpul screws come with some kind of locktite on them.  I don't want to tell you to over torque it but i know i screwed the sh!t out of my moe+ grip to get it tight.

I think its actually 1/4 28

FWIW, I have the PSA LPK with MOE grip.  It too did not have a washer but the grip is pretty solid on the lower without the washer.  No play at all.

Possible my lower has a shallow threading machined in? I dunno, i feel like if i go tighter itll strip and i dont want that to happen and have to heli coil it.

Why dont you go get a smaller screw, thread it in and make sure it threads all the way down. 

IMHO you gotta crank down on some MOE grips. Then they are gtg.

I dont think its the grip, the screw feels bottomed out and there is deff some play/looseness. Ill just throw a washer or 2 on and call it a day. Thanks for the help!

My moe grip had some play in it when I built my lower. Shot a 100 rounds thru it and then I tried and retightened and it got perfectly.

Same lower kit I just used, no washer and grip is nice and snug.

Update- finally got a chance to mess with it again, and you guys were right. While scary it did eventually tighten all the way. It was just real tight the last couple threads. Thanks all!

From what I remember, there's no washer used with a magpul grip, just the screw.

I bought a P-Tac MOE LBK from PSA,   No washer, it does not come with one, none pictured or listed in the item description.  Grip is just fine without it.  They did forget one of the TD springs but somehow managed to throw in an extra trigger pin and mag release spring.  I sent them an e-mail and they sent me two TD springs.

 

It may take them a while but based on my experience and what I've read from other reviews, PSA always makes it right.
