Too bad the old ones won’t show up on the Sarco Inc website
Give it some time.
I quit dealing with SARCO more than a dozen years ago.
They advertised a genuine COLT upper along with a separate COLT barrel assembly, picture showed all the correct markings on the upper, etc....both for SP-1 version.
I ordered them both and they sent me a badly cast upper clone from china or somewhere and didn’t even mention about the barrel. Paid for a COLT, got a $25 crude aluminum casting with bad machining. Total misrepresentation. Sent it back and never ordered anything again from them.
