I'm kicking around re-barreling an AR-15 to shoot .350 Legend. The barrel is on sale for $78. That part is easy to swallow. What's giving me pause is the "cost of ownership". - Stocking factory ammo ($120) - Reloading dies, brass, powder, gauges, trimmer, and bullets ($150) - Magazines ($40) - Different / appropriate optic ($200) - new gas tube/roll pin ($15) Basically, that $80 barrel will eventually drive another $500 in spending. Am I looking at this wrong? Am I missing something?
