Has anyone compared the differences in BCM's Enhanced Lightweight against the government profile barrels? Specifically, I haven't seen anyone comparing the barrel life of the ELW against the government profile. I know it would be a reasonable assumption that the government profile barrel would last longer but is the difference negligible or should it be a real consideration? I tend to put quite a few rounds down range when I am training. I just don't want to get something that is going to be scrap after a few thousand rounds.
