You made a wise investment. Just saw an Air Force 604 upper (no BCG or charging handle) sold for north of $500.I still have 2 original colt m16 uppers (early 70's). Bought them at the 1500 years back for like $175 each I believe.
I just told another member that I was told they were probably Air Force. Wow that's a lot of money.You made a wise investment. Just saw an Air Force 604 upper (no BCG or charging handle) sold for north of $500.
604 is a slick side upper with raised arrow at the windage wheel. They can be "early or late". Check out the "retro" marked items at Ar15.com. The retro dudes have a sickness.
I just lurk at Arfcom. Read General Discussions for laughs.
There are some evil posters there. But a lot of knowledgeable people too.
