I just bought a 1980 made Colt AR 15 SP1 carbine. I had bought an SP1 rifle last year, so I’m thrilled to have a carbine to go with it. Those are quite rare here in Switzerland. Paid $ 1600 for it.
And it has a few strange features, if anyone has infos pls chime in.

So what’s the story, did Colt build some full autos SP1 carbines ? Or was this transformed by a previous owner ? The auto sear is missing, and I bought this carbine as a semi auto. Could the sear be installed ? I already have two full auto rifles, an M16A1 and an XM177E2.
