M1 Garand front sights are not interchangeable with Norinco M305 or any other brand of M14. Different dovetail, height, etc. Garand rear sight assemblies, however, are good to go, and many have happily changed out their Norc rear sight assemblies with USGI, Italian or SAI. If you want a new front sight because your Norc is a little off, you can go with USGI, SAI, SEI, or other aftermarket suppliers. Hope this helps.
