Sir, your country has the honour of having the worst service rifle commonly fielded today.
I've never used anything else myself, so I'll trust you on that one. Seriously though, I have heard all of the complaints about it. They seem to hate dirt and sand more than the average rifle for one thing.
L85A2's are better. But that's like saying that chugging sulfuric acid is much better than chugging hydrocyanic acid.
The A2s have a better cocking/charging handle, that much I know. Not sure what else.
Those things look like they'd suck if you fired 'em from prone...
Magazine changes were always a little awkward for me, that is for sure.
We could just have bought a load of M16s, or if we waited longer to 'upgrade', M4s from you guys. The SAS in GW1 were happy to use the M16s.
