OUTSTANDING!!!!!!
About 5 years ago, I built my son a retro XM177ish carbine (below). He wanted the M16A1 flash hider on it, so I replaced it after the picture was taken. We have shot it a lot through the years. It does 1.5 MOA with iron sights. It also has an original Colt Fiberite stock! The stock set and 603 upper were both nearly mint
My son was up for Thanksgiving. He was admiring my M4gery build I had just finished. He asked if I still had a retro AR, too. I told him I did and showed him the 602 build. As were talking, he commented "you sure do like your retro ARs! I like my "Shorty" but wish I had a flat top with red dot." BTW, all of his firefighter buddies have "golly gee whiz , tacticool M4geries" and he has a retro. Seeing a golden opportunity, I said "Well, son I would be happy to trade guns (except lower receivers which are registered by SN to us in Kalifornistan)" So he took this below and is sending me the above retro Carbine! Life is good. I also sent him with an A2 grip, and am getting the A1 grip back. For now, I will probably run it as my featureless light weight KISS Carbine with pinned stock and hammerhead or Kydex paddle, so I can use my high caps. I will keep the stuff to restore it to its 653ish self, though....
I wanted to do a retro build instead of the M4gery ,in the first place, but the real Colt Fiberite stock and 603 upper cost almost as much as my whole $389 M4 build!
