I would prob get the m1a because it's shoots a hard hitting round same as the ruger scout, but is also semi auto like the mini 14. So to me the m1a is more versatile!
Depends on what your style and preference is.... I personally bought the M1A first, just most my style and preference at the time. Bought a mini-14 aswell shortly after. Both are great guns, no experience with the Gunsite but i hear good things aswell
