I'm looking to build an AR15 to replicate the looks of the M16A1 my dad used in vietnam. Just looking for some tips on the build or some pictures. Also any information on making sure i get the engraving right. I'm thinking of buying one of the colt parts kits off the internet then a Nodak spud lower receiver but with the parts kit i need to have the front sight fitted to the barrel and the barrel parkerized so if you know of any gunsmith that does this work that info would be awesome. Thanks
