Cheers Kev, that makes sense, as you say, differences in all three. the mag well lightning cut on the CAL rifle, is similar to the Fal, where the UK and Lithgow opted for a simpler narrow scallop.

It does makes you wonder why they would change things like the gas block assembly, where even the angle of the gas bleed channel was altered...
