SIG Manurhin 543 Semiauto: I Really Like This Rifle
This video provides an in-depth review and technical breakdown of the SIG 543 semi-automatic rifle, presented by Ian McCollum of Forgotten Weapons. The SIG 543, a carbine variant of the SIG 540 series, is explored for its historical context, design features, and operational mechanics. The review highlights its development stemming from SIG's collaboration with Beretta and later Manurhin in France due to Swiss neutrality laws. The video includes a detailed field-strip demonstration, showcasing its long-stroke gas piston system and AK-like rotating bolt mechanism, while also noting its unique features like a longitudinal hammer spring and optics mounting points. Shooting impressions emphasize its pleasant recoil and handling, despite a noted subpar trigger.
