Timing is probably bad, but my youngest turns 18 soon. He has developed an interest in the AR platform and wants one for his Birthday. I already read VG's thread. So, where do I start to build one myself? Staying with .556/.223 for cartridge. If costs are out of hand with an AR, we may go semi auto handgun instead. Dad and his bolt gun/revolver love is getting boring I guess. Thanks guys. mtmuley
