Springfield MA9106: The Standard Series is a faithful semi-auto only recreation of the original M14. Keep in mind that the Standard M1A is as well suited for a day at the range as it is for filling that special place in your military collection. All the design features that the Armed Services found essential for a battle rifle make the Standard M1A a great shooter. The windage and elevation adjustable rear sight minimizes the effort required to zero the rifle. The two-stage military trigger, detachable box magazine, op-rod and roller cam bolt call to mind the rich history of the M1A while providing functional ease of operation and legendary reliability.
