WW2 Firearms trivia question

[Greybeard]

Hello SG- Correct..

The AG-42 was also one of the first production firearms to incorporate a vented barrel design to reduce felt recoil.

With the heavy weight (10.5 lb), smallish 6.5mm round, and the vented bbl, it's like shooting a .22 with a reach of 800 yds..

Ok - next question:

Along with the M-1 Garrand, the United states procured another semi-auto rifle for military use. This Rifle was issued primarily to the US Rangers that served in China and the USMC (until the Garrand became available). Also Chambered in 30-06 and named after it's designer. This was not the M-1 Carbine..

This same design could be readily converted to use as a LMG, to be used in the same capacity as the BAR

Can you identify this firearm?
