For the Forge question, it forges into... http://combatarms.wikia.com/wiki/E_57_Musket#comm-33948. Personally, when I forged a 30 day M39 EMR Desert, I somewhat regretted it, I felt like I was just better with the EMR over the Musket, but of course that's just me. Also, I'm not a big fan of Muskets anyways... I think that the M4A1 Desert is just like the normal M4A1, except for the obvious looks. GP Perms are usually around 100k GP, and the weapons are usually lower ranking weapons like M4A1, G36, etc. But hey, at least it was for GP, which you got for free (that is, if you never got the GP by buying GP Hazards or GP Normals) instead of using NX.
