Hello,

What do you think, is it 0.30 or 0.50 cal?

Thank you in advance!

Looks like 30 cal to me. Especially with the empty shells beside the last pic

I have to agree, .30

Thank you guys!
I posted this request also here M2 0.30 or 0.50 cal? and it seems to be 0.50 cal...

Those look like .50 shells to me. Hard to tell without something in the picture for scale, but the barrel looks a little too stubby foe a .30, and that round thing at the base of the barrel could be some sort of turret mount.

Those are .50 M2s. The giveaway is the number of rivets in lower front of receiver.
