Ok, here's what I think of the weapons - very exhaustive. I cant say theres any weapon I dont like or wouldnt be able to use. They all sound great as well IMO.
SMGs – Like in games past, they all have a decent amount of recoil, but some have the option to attach a grip to lower them. There is no slow firing high power SMG like the UMP45 or Mp40….thank god.
MP5K - Its much more similar to its MW1 counterpart in look and feel than the MW2 MP5. Iron sights are pretty good, recoil is significant and very random. It can kick to the side just as easily as it does up. Medium fire rate and reload time.
Skorpion – EXTREMELY accurate. Very little spread, no recoil. Probably the closest to a laser beam in the game. But also only a 20 round clip. Iron sights are pretty meh as theyre just the flat top of the gun like a pistol, and you cant even attach a sight, so its hardly long range. Medium fire rate and reload time.
MAC 11 – Fires a bit faster than the MP5, with quite a bit less recoil. Reload time about the same. Iron sights are OK, similar to scorpion. Medium reload time.
Ak74u – Pretty similar to the Mp5 – decent iron sights, and while it does recoil, it seems to spread around evenly rather than kicking constantly in one direction, and overall I’d say less than the mp5. Medium fire rate and reload time.
Uzi – High rate of fire, and very high recoil, equal if not surpassing the mp5k. Seems to reload pretty fast, and has a 32 round clip. Iron sights are pretty bad IMO, blocked around the side and pretty busy in the middle.
PM63 – Fast fire rate, but small clip. Similar recoil to mac11. Pretty fast reload, especially if you don’t exhaust the clip.
MPL - fast fire rate, I’d say medium to fast reload. Decent clip size at 32, pretty average recoil. Iron sights are pretty busy in the middle but still solid.
Spectre – Very high rate of fire, and it has the recoil to match, similar kick to the mp5. Reload is about average, the iron sights are pretty bad though, blocked on the immediate sides leaving a pretty small box to look through.
Kiparis – Again, very high ROF, with a pretty fast reload. But it kicks like a donkey, often flying up and to the right pretty fast, probably more than any other SMG. Iron sights are good, similar to ak74 but quite a bit busier in the middle.
Assault Rifles – Again, the thing to know here is that ALL rifles have some kick, unlike MW2. And again, there is no slow firing, high power rifle like the SCAR. As in MW2, the ACOG significantly increases the already present recoil.
Enfield – Relatively slow firing, similar speed to the ACR. Mediumish recoil, feels like it should be pretty powerful. Basically your average starter rifle that’s average in all ways. Good iron sights, medium reload.
FAMAS – Very high ROF, recoil is present but not outrageous. Reminds me a lot of the F2000. Very similar iron sights to enfield and other ARs.
Galil – Similar ROF to enfield. Much wider open center of the iron sights, but still blocked on the sides. Big clip at 35, but reload is slightly slower. Perhaps slightly more recoil than the enfield.
Aug – very high ROF, perhaps slightly faster than the famas. Reload speed is medium, iron sights are pretty good, and it doesn’t seem to recoil outrageously more than others.
Ak47 – Actually seems like it could be one of the more accurate ARs, recoil is relatively controlled. But the iron sights are awful, as they are very busy in the middle, and during fire the gun kicks to the point where youll hardly be able to see your target. Youll prob want a sight with this. Medium ROF and reload.
Commando – DEFINIETLY the most accurate full auto AR. It still kicks a bit, but its more of a spread. Its basically the M4 carbine from MW2 with a little added recoil, perhaps a slightly slower firing rate. Iron sights are OK, definitely one of the busier ones in the center, but no where near as bad as the AK. Reload speed and fire rate about average.
M16 – 3 round burst. Basically feels like its returned unchanged from MW1-2, iron sights and all, which were never my favorite. 3 round burst, no recoil, very fast reload, but without SP, probably will need more than one burst to kill.
G11- 3 round burst. This weapon is a bit ridiculous. Super fast 3 round burst, no recoil, very accurate. Reload speed decent, iron sights good. 48 round clip! I have to imagine this rifle is very weak and takes at least two solid bursts to kill, otherwise itll probably be a bit unbalanced. However – you have only two attachment options – one is the “low-power scope”, which is like the ACOG from MW1, where it zooms way in, takes up most of the screen, and sways like crazy, and you cant hold breath. The other is a variable zoom sniper scope where you can. Still, it does kinda seem head and shoulders above the rest, but it’s a very high level unlock and requires you to unlock all other ARs first, so hopefully it wont be too commonplace and dominant.
M14 – Semi auto. Similar to MW1. Kicks like a donkey, but its always straight vertical, and always returns exactly. Will probably be a deadly medium-long range rifle as long as you can moderate you rate of fire. Honestly, the grip doesn’t make much difference. You can only fire maybe 25% faster or so before losing accuracy. Iron sights are a bit tight, similar to the m16.
FAL - Semi Auto. Unlike the M14, the recoil doesn’t always kick straight up, it’s a bit more random. Both are very accurate, the M14 is a bit more predictable in its recoil, with the FAL giving a bit more spread. The iron sights are fantastic though, very wide open and not too busy in the middle.
LMGs – Unlike MW2, the majority of LMGs have AR sized clips, with the exception of the M60. Recoil is on average pretty high, and reload rates slow.
HK21 – Fairly accurate, 30 round mag. Recoil probably about equal to the AK, but move and aim speed is slowed. Pretty slow reload time, but not ridiculous. Iron sights OK, kinda blocked on the side, but still usable. Reminds me a lot of the AUG from MW2.
RPK – Basically a very heavy AK. Recoil is significant, and reload time is slow. 40 round clip, but can use dual mags. I have to imagine each shot is powerful, and it gets my vote for best iron sights in the game. You simply don’t need a sight with this one.
M60 – 100 round clip, 100 round spare. Recoil is fairly ridiculous, and rate of fire is slow, probably about SCAR-H speed. Iron sights fairly good, similar to most ARs. Takes a long time to reload like most MW2 LMGS. Grip lessens recoil significantly, but its still very present. You simply are not going to kill anything at a distance with this thing full auto.
Stoner 63 – Basically a very large assault rifle. Fire rate is very fast, and recoil is very high, but reloads pretty fast. Only 30 round clip.
Pistols – Let me say straight off the bat that the upgraded iron sights are a joke. Theyre hardly an upgrade. Very, very minor difference.
ASP – Small clip at 7, recoil is minor and kicks straight vertical. Reload time is crazy fast, especially if you don’t exhaust the clip. Seems to sway a tad less than the others. Basically, a great finisher.
Makaraov – Very accurate, little to no recoil and spread as fast as you can pull it, and 8 bullets. But reloads noticeably slower than the asp, yet still pretty fast since it is a pistol. It does have noticeable idle sway, unlike primaries.
M1911 – Hardly distinguishable from the makarov, with noticeable idle sway again.
Python – Kicks straight up, only 6 shots, and SUPER slow reload (one bullet at a time). Speed reloader definitely helps. No idle sway at all.
CZ75 – Also very similar to the makarov and m1911, sway and all. 12 round clip, and has an attachment to go full auto, which fires about as fast as a SCAR-H. Probably my favorite pistol of all due to this.
I cant really comment on the snipers without someone to shoot at, because the real differentiator there is how many hits it takes. Theyre all usually very similar.
