In my experience, I‘d have to go w/ the C7. When I went in, I had previous bias towards the C2, but I got over that quickly enough. I found the C7 to be a good companion. I shot marksman and I adjusted to the Elcan, although I‘d have preferred the option for iron or an Aimpoint, situation depending. Only gripe, I never figured out how to control full auto. No matter what I tried, that barrel just jumps up. On the hip is about it, but that wasn‘t exactly accurate. Thing is, full auto isn‘t meant for accuracy at range, it‘s CQB, so who‘s counting. I‘m just being anal.
I‘m interested in a few others though, the AK‘s seem to still be the kings of the field in terms of abuse and neglect. Anyone can pick one up and use it, which explains the popularity of these things around the world. I‘ve heard good things of the Steyr‘s, always interested in Bullpup designs. I‘d like to play with an Enfield SA89 one day, at the range, doubt I‘d want to rely on it. H&K make‘s excellent products, like to try some of those rifles also. I‘m also curious about the Galil‘s, like to try those. Basically, I have a shopping list of arms I‘d like to experiment with. But I‘ll keep it realistic. (I have a few Ferraris‘ I‘d like to take out this weekend, but my ‘89 Saab will have to do)
I like the C7, I‘m following the replacement with interest. I‘m all for a 16" carbine as has been suggested. I wasn‘t armoured, so I didn‘t get a chance to try a C8, but I liked them. Maybe something along the lines of the US M4 is a good way to go. We‘ll be using M16 variants for years, I doubt we‘ll be getting OICW‘s in the near future (doubt I‘d want it anyway).
