I finally got a line on an 80% AR-10 upper and a parts kit to built a rifle.

Anybody have any experience with this firearm?

(Talking about the original 1959 version, not the new, current production one.)

Booth,
did you get a semi AR-10 lower ??  If so, which manufacturer ?  Portuguese upper ??

Boothe

What does 80% mean...80% completed ?

Yes 80% completed , When a reciever is only 80% it is not considered a firearm so it doesn't have to go to a ffl...

Oh ya and pics!

Must have been something I asked ??

At any rate this thread has gotten a good many reads and not much info is here.
------------------------------------------------

ArmaLite designed the AR-10 back in the 1950's but licensed production to a company in Belgium, Artillerie-Inrichtingen (AI).

AI probably manufactured about 6000 AR-10's primarily for two countries - Sudan and Portugal.

Back in the late 1970's early '80's these rifles began to be phased out and a couple of importers began to bring uppers back into the U.S..  Some had the receivers burned in half while others were kits made-up primarily of uppers.

Americans being the entrepreneurs that we are starting buying these upper kits and manufacturing semi-auto receivers.  There was a guy named John McGlothlin up in Ohio that started the semi manufacturing business, Speciality Arms and bought receivers manufactured by a company called 'TELCO' - also in Ohio.  Several other manufacturers bought AR-10 upper kits and manufactured semi-auto lowers - Central Kentucky Arms, Ky., H&H Enterprises, Cal., and Sendra, Il., were the primary players.

Anyway, that's why I asked the thread poster which lower he had.

These semi-auto rifles are pretty collectable and bring somewhere around $2500-$2800 for a good one.  The one I own has a TELCO lower and is labeled "XM-10".  

(This is the very short version with lots of room for omissions - and, of course, always room for errors.)

i hope the price comes down on the ar10's, i really need one
