M1A/M14 Gas Block Shim Set

[james_bond_007]

It was recommended by IslanderMyk that I install a Gas Block Shim Set to my M1A to help improve accuracy.
I had a hard time finding one.
Not a typical Midway or Brownell's item.
Had trouble contacting sources I found on the web.

I finally found one here http://www.calguns.net/calgunforum/showthread.php?t=552745

I'll install it and see if things get noticeably better.

One of the guys on M14 Forum have been posting those for sale. I haven't tried one yet though.

I am curious on how it does.
