Depending on the gun, that can be true. A barrel blank for an M1A rifle costs about 30 bucks. Thats nothing but a steel bar with a rifled bore through the center. We have about an hour of machine time to complete, which puts the cost at about 85. If an M1A retails for 1400 bucks, I'd say your math is a little off. 1911 .45 pistol barrels, can be purchased completely machined in Stainless domestically for about 75 bucks. Overseas they can be had for half or a little less. A 700 dollar 1911 has a barrel in it that cost about 35-40 bucks to make. I run production for S.A., b.t.w.
