I sold Reed Two Stoners and 8 original AR-10'S' back when with the one quick change heavy barrel. model. a carbine, a factory Semi threaded for suppressor yeah {Original}the shorty Carbine, and a few others all new cond. He has the best in the u.s.a. for sure.I bought from Chuck Dorchester the last remaining pile of AR-18 and AR -180s they had barrels, parts, hand guards. springs.bolts unfinished receivers, five crates of it. and the prototype AR-10 AR-15 Belt feed device. {He said no need for it} they did whatever projects they wanted. remember this was 1979 through 1981, so every yahoo and his brothers son. has spread that stuff all over by now..
It was all a part of AR history, and won't be repeated again. My 1980 Catalog picture was Serial #1040 on the ARM LTD. catalog.
yep good times.Thanks for the post it brought back some good memories.
