in the past ive seen complete uppers in for sale in places like Sportsman's Guide. i know they arent the best supplier of stuff in the world but im in need of an early (no FA) upper with triangle handguards, 3-prong flash hider and early drum rear sights for my EARLY Air Force M-16 retro rifle...

i drew one in the Air Force with a serial number just a pinch over 12,000 and while i wouldnt compete with it (have an A2 and a scoped A4 for that) but id like to have one to commemorate my service. Im doing an 80% lower so i can get is engraved specially for me lol...
