My Dad dug out his custom M1A he built back in the day when he was in AMU and he's planning on doing some groundhog hunting with it this summer.
Specs for it are:
Early Springfield M1A reciever
Hart Super Match Barrel 1:12 twist
American Black Walnut Medium Weight Match Stock
National Match Sights
National Match Gas System, Flash suppressor, spring guide, and OP-rod guide
Brookfield Precision Tool M-25 Mount
Steel Weaver Grand Slam rings
Nikon Buckmaster 6-18x40 scope
Rifle has a crisp 3.5lb trigger pull and is fully accurized and bedded with DevCon. Shoots 3/8" inch groups at 100yds and is truly a sweet rifle to shoot. Definitely a serious long range rifle and having the accuracy of a bolt gun but the capabilities of a gas gun make it one all around deadly package. This is one of my Dad's favorite rifles and in his opinion the M1A/M14 is the best all around sniper rifle when put together right.
