Norc M305 and AMMO

When they came out, they cost $400....so I don't think anyone cared about barrel life.

Probably 5-7,000 rounds? 

I found with one of my .308 bolt rifles that the accuracy dropped off between 6-8,000 rounds, and the throat erosion was huge. 

The higher possible ROF from a semi means you'd probably see a shorter barrel life.

Good to know.  I have seen some barrels on the CGN EE that are not that bad in price.  But when it comes to change it out I may just buy an M1A
