wow that .50 looks great, is there any difference between that one and modern .50? like the ones I ocassionally see on abrams MBT they seem to have three rods surronding the barrel, not sure but just asking

The standard M2 hasn't changed in decades (except for the barrel). Most modern US vehicles still use the twin wood handles with butterfly triggers and wooden charging handle. Wood handle color varies from painted black to a dark brown stained color. In other words, the same Ma Deuce on an M4 Sherman is basically the same one on an M88A2 HERCULES.
The M2 on the Abrams tank differs from the standard M2 used in a flexible mount. Instead of the wooden charging handle, it has the M-10 charging handle. This is basically a cable pully that you can yank from the safety of the hatch in the protective cover opening. The wooden hand grips and sights are not present on the M1/M1A1/M1A2 .50 cal. The M-10 charging handle first made its appearance in the cupola of the M48 Patton tank. The M60 series tank used that lousy M85 .50 cal. How I hated that thing, but that's another story.
Anyway, an M1's M2 is virtually useless if placed in a flexible mount and a normal M2 will not fit into the Abrams' CWS mount (charging handle gets in the way, I've tried it).
About the rods, as explained, it is the blank firing device or BFA. The reason why you see it only mounted on a few M1s is because the design of the BFA makes the barrel of the .50 cal nose heavy. When maneuvering cross-country, the extra weight makes the nose of the weapon want to go up and down like a see-saw. That strips the brass gear that elevates and depresses the .50 cal. Once that gear is stripped, the .50 cal won't elevate or depress when you turn the elevation knob. Believe it or not, an inoperable .50 cal (or any machine gun) deadlines the tank. Smart TC's don't mount the BFA.
