Match Target Lower Receiver Parts Kit

I saw these parts kits for sale on Gun Broker in February and March 2019. These parts kits sold for roughly $90.00 each. The auction description stated the following:
“These kits are approximately 15 years old and have the civilian semi auto large diameter hammer and trigger pins, the front pivot pin is not a push pin but looks like one. In the match target colts this front pivot pin is identical to the push pin in shape but is threaded on the end opposite the head and is held in place with a screw seen in the pictures. The threaded pivot (front) pin is the only component that is different from a standard colt push pin type kit.”
