Hello, I have a Springfield M1A Scout Squad dropped in a Troy MCS. I love the configuration, I love the gun. I have been in the Army the past few years and have only had the chance to shoot the rifle on and off every few months. I am getting out soon and plan on doing a lot of shooting out of this thing. I wanted opinions on the durability and life span of a Springfield barrel, and any other alternatives that are geared towards high quantities of rounds through the barrel. I use standard 150 grain FMJ usually. Thank you for your help.
