I am in search of the mysteroius second screw for my Trijicon. I have it mounted in an ARMS #19S mount, but only used the one screw that shipped with the scope to attach it. This has always bothered me, wondering not if/but how much this would affect my zero on the scope.

Does anyone know where I can pick up a second screw for the Trijicon? Anyone know the dimensions so I could just go pick one up at a hardware store? (my dad always said I had a screw lose, I guess this is proof he was right).

I'm sure you will get several good suggestions.  I picked up some stainless steel low profile hex from boltdepot.com.

Product #4404
Name: Socket products, Socket button head, Stainless steel 18-8, 10-32, 1/2"  $.012 each

Product #4403
Name: Socket products, Socket button head, Stainless steel 18-8, 10-32, 3/8"  $0.11

Of course shipping more than the screws....  Couldn't find easily locally.

You da' man. Mucho gracias senor. Your kindness will be paid back tenfold.

Thank you again.
