Can anyone tell me what hex size the Aero Precision set screw is, so I can buy a long enough tool for it:

aeroprecisionusa.com/nylon-tipped-tension-set-screw.html

I had a b**ch of a time getting the Magpul grip on and now I cannot figure it out.  Sure would be nice if they mentioned that on their site, I googled around and cannot find the info anywhere.

I don't have and Aero lower, but do have a Mega that has a tensioning screw. It's 1/4-28 and takes a 1/8" allen wrench. I assume all manufactures that include the screw use the same size. You can buy replacements

1/4 by 28 is pretty much what everybody uses..

Look around you can find a long ball type 1/8 inch allen wrench. makes it a little easier to get it in. .

Yup 1/8 did the trick, but I actually had to use a short one to get the angle within the grip to fit it in.  Not sure a long tool would actually clear the lip to get in there.
I was planning on tightening it every time I put the rifle together, to keep it nice and rattle free, but now I am starting to think that it's not worth the hassle.  There is very little wiggle when the screw is still allowing for the pins to come out easily and I don't notice it at all when shooting.
Thanks for the help.
