Guns, Dogs and Blades QnA

No field grade currently. Only Rack and Expert right now.
I looked at a Springfield M1 and Remington '03 with USMC sights that had been Rack grade plus. Both had new parts and the '03 needed a new follower otherwise it was a good shooter. (The USMC front sight is a full hood with a wide blade and a slightly larger rear aperture).

Unconventional. You memory may be accurate.

The iron sights of the M1 carbine are essentially the same as the Garand. My understanding is basically the same sight picture used perhaps as early as the M1917 (American Enfield), the 03A3 (but no windage adjustment), and continued through at least the M16A2. I've used the '03 with original front sight and for older eyes the narrow front blade and position of the rear sight make it a bit tricky without the right glasses.
