Garand barrels in 7.62x51 nato
Sarco is advertising a group of garand parts that they say were made for Italy and can be used to convert a garand to 7.62x51. The group consists of a barrel which is 1/2 inch shorter than standard and chambered for the nato round, a shorter op rod and stock. Have any of you seen these parts? Is the conversion possible and is it likely to result in a functional rifle?

7.62 vs 30-06 M1 gas port requirements
I do not doubt the above information that the 7.62/308 M1 requires a larger gas port than does the 30-06 M1 but my question is WHY? It would logically seem to me that both the 7.62 and the 30-06 develop approximately the same chamber pressure (~50K PSI) and the bore length from the chamber to the port is approximately the same (though the 7.62 case is approximately ¼ inch shorter than the 30-06). Perhaps someone can tell me why the larger port is required for the 7.62/308.
Just curious.
