Welcome to Gaia! ::

The MP5K seems kinda neat if you're going for easier concealment but it isn't gonna manage well on recoil being so much lighter than a MP5N, having no real stock attachment, and that vertical grip. Vertical Grips are fine for the really small SMGs like MAC-10s and Micro Uzis (Which still have horrible recoil anyway) but there's no real solid way to compensate for recoil without a heavier gun. Vertical grips just complicate things, I'm not even convinced they actually work better than the standard barrel guard grips for steadying your aim.

Well the Colt Anaconda is a magnum, there's a notable difference in the type of ammunition. For .454 casull those are definitely compacted. Rifle casings just don't fit in handgun magazines. If a handgun was made in such a way you'd never get your hand on the grip. I think those really were just oversized handgun rounds, and with the limited casing space for powder grain they'd probably actually be much weaker than the real thing. .44 rounds for a Colt Anaconda would likely pack a lot more punch. Still bullet diameter isn't the only factor in determining muzzle velocity and stopping power. Much of it has to do with the design of the casing as well.

I think I'll decline on adding the Coriolis Effect. I get how important real world physics is to taking a proper shot and really everything in plausible storytelling. The Coriolis Effect is inescapable since we're on an actively spinning planet. But this might get into a depth of realism people don't want to have to consider when RPing. If someone were to bring it up in their RP they'd probably be met with resounding moans and accusations of killing the escapism.

Yeah, that was pretty awesome. Guys like that are why charging in spears first is dead. A M249 SAW is designed to mow down targets with bullets. He doesn't have to use them accurately either. With the sheer amount of bullets they pour out, that broad side of a barn would look like a gigantic slab of swiss cheese. Those are armor piercing rounds mind you.

Well, AK-47s have a lower rate of fire. If you're trying to keep below 650 to 700 RPM then you're basically stuck with the AK-47 or a Chinese variant of it. You could get a FN SCAR or HK G417 if you want something more modern.

If you could somehow work you way around to getting your hands on an experimental Korobov TKB-022 Assault rifle you might be able to get your firing rate below 600 RPM. It is experimental though and it lost out to the AK, which then became more wide spread.

Lowest I can find is in Singapore, the SAR-21 bottoms out at around 450 RPM. If you want an even lower firing rate consider an old battle rifle.

So do automatic pistols. I covered "semi-automatic" under gun function and "Shotgun" under gun types. I'm not going to go into detail on every precise type of gun. It should be up to the person who chooses a gun to know how it works, what ammunition it uses, and what it's capable of.

For that matter I think I'll leave out pointing out Bullpup designs vs standard configurations.

My guide is gonna be like 10 times longer if I include ammunition types. There is a huge amount of variants for the same chamber sizes, but then of course there's chamber sizes into the sky. 9x19 Parabellum could be Lead, wad cutters, full metal jacket, semi jacketed or full jacketed hollow points, lead hollow points armor piercing rounds, the list goes on.

Shotgun ammunition types are plenty of fun too...

High cap mags are self explanatory.

Except for the mini reflex scopes, there isn't much of a difference. They're red dot target sights in a lens. Honestly I don't see why they're necessary but that's my opinion. The iron sights are just fine at close combat ranges. I'll add em later.

That's not an M4A1 carbine, I'm pretty sure it isn't, anyway.

I see it now. But wouldn't the SIG 556 be much simpler to mistake for the M4A1, considering the similiar qualities the two share.
