I remember seeing these weapons in the catalog section of the Guns and Ammo Gun Annual back in the 60’s-70’s. I never knew how complicated(leave it up to Sig) the internals(28min.) of this weapon were and yet so functional/reliable. IIRC, the Sig 510-4 was the .308 version. Chamber details at 22:55min. and rear sight details at 11:20min.
