After thinking about it in my fitful feverish sleep I have decided to revamp my post

because you did specify FAVORITE.
7.62x51mm
Here are my basic standard issue favorites:
FN-FAL/L1A1, M14 or G3A3 would be a heck of a start. I like features of each of these rifles. And I have owned a semi auto version of all of them except G3A3( though I did have a CETME) and quite honestly for my purposes like shooting through cover and barricade they all work very well. Though they are all a big long and heavy especially when dismounted. I really do think the typical soldier in twilight would be walking most of the time. But I would rather have a firearm that could reach out and touch someone, maybe trying to snipe from the forested edge of a field. Id rather take 2 or 3 shots than have to waste a whole belt of MG ammo to get them. I also like the ability to launch rifle grenades at long distances with all these rifles.
Fantasy or hard to find favorites:
G3A4K if I could get my mitts on one of these rare carbines from an SAS soldier it would be a great option other than muzzle blast.
5.56X45mm |
Baisc standard issue favorites:
M16A1 or CAR-15 or COTS carbine. Light weight is plus here especially with the carbine when on foot. Though I am not really excited about the terminal performance of the 5.56x45mm cartridge they work great in full automatic. I would not want a newer gun with 3 round burst capability. Also the ability to Mount an M203 grenade launcher would be helpful, so if I had my druthers Id get an M16A1 with M203 mounted and spray paint it green.
FAMAS A1
I would choose this rifle specifically for it's small sized and high cyclic rate of automatic fire but I don't know why they only had a 25 round proprietary magazine. That being said they have a very twilight 2000ish ugly look and would be great for clearing buildings.
Fantasy hard to find favorite
Steyr AUG A1 Commando 14" barrel bullpup with built in optic and two stage semi-auto/full auto trigger. I would run it with 42 round HBAR magazines for a compact spray gun.
9x19mm
Basic standard issue favorites
Browning Hi-Power/L9A1 these are great 9x19mm handun and I would very much attempt to locate one.
Fantasy hard to find favorite
L34a1(Mk5) Sterling. I don't know how many SBS typs would be wandering around, but it's an excellent firearm if one could be had. That being said I'm sure it would extremely rare but really cool.
