The M1A is a great sniper rifle for several reasons. First, it is extremely accurate. The M1A can consistently hit targets at long range, making it ideal for snipers. Second, the M1A has little recoil, meaning that it can be fired rapidly and accurately. This is important for snipers, who often need to take multiple shots in quick succession. Finally, the M1A is relatively lightweight and portable, making it easy to carry on long missions.
