Good choice, the Scout was my very 1st M14 type rifle.
The 10 round magazines are easier to rock in & out of the mag well.
44MAG.com is an excellent source for C.M.I. mags.
LAW483.com can probably make a lightweight Walnut stock for you,
and a rubber recoil pad is quite a bit lighter than all of that metal.
Iron sights or even a good 1 or 2 MOA red dot should be perfect @ 100 yards.
Scout scopes are great, but I would replace the M1A Scout mount with the
SHG from M14.ca. It allows you to position your optic very low and you normally
do not need to add a cheek riser. You can also co-witness your irons through
most Aimpoint RDS that are mounted low.
You can shorten the rifle 1/2" by replacing the current muzzle device & front
sight with a GLFS (H or D) and DC Vortex flash hider from Smith Enterprise.
Both of these are 18.0" barrels
