So my dad is retiring after 35 years in the army and DOD civil service to a really nice place that mom and him bought cheap when the market in Phoenix tanked. He and mom intend to remain residents of Idaho where they will spend summers and winters will be spend at "Casa El de Fsjdw2 Sr" (hand done mosaic on bottom of pool, jacuzzi, sauna, 5 bedrooms, gated community, ect ect) . Dad's firearms collection consists a .38 antique from wwII(uncle's bring back), and a .30-06 remington 700 both at the summer home in idaho. I will be visiting in winter and am curious about gifting dad a stripped lower and parts kit so dad can build a replica ar15 (m16a1 replica with no switch). Will I legally have to transfer the lower through a dealer? If so who is a good dealer(cheap, and stocks some .223 for sighting in reasons) in the Peoria area?
