I just got a MIAD for my latest build, and the set screw for the trigger guard front strap is not in the package.  The booklet calls it a "#5-40" setscrew.  This is not a typical size, and I can't find it locally.  ACE Hardware, Home Depot and Lowes aren't an option since they all stick to pre-packed assortments and displays that don't go below #6 screws (here, anyway).  Grainger doesn't list anything under #6 screws either.  I could order some from Smallparts, but I don't need 100, I only need 1.

Is this actually a #5-40 screw?  Does anyone have a good source for only a few?  Would it be worth my while to contact MagPul about this?

Probably. They'll more than likely be happy to toss one in the mail for you.

I had one that was missing that screw and contacted Magpul.  It took them a couple of weeks to get it to me but they did it at no charge.  Luckily, I wasn't in a hurry with that build.

Magpul will probably send you one pretty quick.

The size of the screw for the MIAD and the aluminum enhanced trigger guard is 5-40 x 5/16.  Several people have stripped the head of the set screw when trying to install it.  If you look in the Magpul Industry forum there is a thread with photos of a pan head screw replacement that looks good and would solve the stripping problem.  The pan head uses a slightly larger hex wrench, but the screw is still the same size.  Coincidentally, a screw from KNS pins is the right diameter, but only 1/4 inch long, however it works pretty good as a replacement.

Did you check the trigger guard?  Two of mine came with the set screw already installed in the trigger guard.  I cannot believe ACE did not have a 5-40 since that is a very common tap.  I have purchased 5-40 taps and set screws there many times.

I didn't look at the trigger guard for the screw-I was looking for it in the bag with the grip screw or taped to something. I'll look closely for it IN the guard, and if it isn't there I'll contact Magpull. Thanks all!

You probably may have already done this while playing around with the straps, but look inside the pistol grip itself. My hardware was inside in a plastic baggie.

That baggie had the main grip screw and a roll pin to make the back strap semi-permanent with.  Nothing else.  Thanks for the advice, but that was the first place I looked.

I looked very closely (good light, even magnification) and there's no screw in the trigger guard, in the rest of the package, or taped to any other part.  I've emailed Magpul about it and I'll post when I get a response.

I was missing the screw for my MBUS.  Emailed them and had one 3 days later.  2 days later I got another one in the mail and another one the day after that.....
