The Cei Rigotti is a fascinating early Italian self-loading rifle design that was tested in several countries, but never adopted or put into production. I had a chance to disassemble one at the British REME museum in Warminster back in 2012, and the video has not gotten much traction because of how small the channel was back then. So, coupled with a bit of backstory about how we filmed it, this makes an excellent Throwback Thursday video. Enjoy!
