Mane Six (and more) go Gun Shopping! (updated)

Nice!
Here's a few I came up with:

TWILIGHT SPARKLE:
COLT M4A3 SOPMOD www.motionpicturearmourer.com/…
Everything about this rifle screams "standard issue", which is why Twi would swear by it. It's also near-infinitely customizable and uses some of the most plentiful ammunition in the world.

RARITY:
COLT M1928 SUBMACHINE GUN www.thespecialistsltd.com/file…
Designed for soldiers in the trenches, used by Prohibition-era villains, the Thompson is the gun that made the twenties roar. And if you're the pony everypony should know, you need a damn good reason for them to know you.

APPLEJACK:
WINCHESTER MODEL 1897 12G  www.thespecialistsltd.com/file…
Forged on the benches of master gunsmiths and tested in the trenches of WWI, this is one badass boomstick you don't want to be on the business end of. Especially not when Applejack busts out the 97's party trick...

RAINBOW DASH:
MAUSER MG-42 www.nazarian.no/images/wep/163…
Too fast for its own good and with no real durability to speak of, this bonkers machine gun was still able to shred entire platoons of Allied troops during the European campaign of WWII. Its amazing 1200 rounds per minute was unheard of in 1942, but it came at the cost of a gun that was so fast to overheat that the barrel had to be changed with every reload. Perfect for a reckless adrenaline junkie like Dash.

FLUTTERSHY:
MOSIN-NAGANT 7.62x54r.net/MosinID/0003.jpg
German troops laughed the first time they saw Soviet infantrymen carrying these awful-looking rifles. Joke was on them, because the Mosin rifle went down in history as one of the most accurate and popular bolt-action rifles of the 20th century. And staying away from the action is definitely Flutter's style.

PINKIE PIE:
GENERAL ELECTRIC M134 "MINIGUN" arniesairsoft.co.uk/news2/wp-c…
What's better than a party cannon? Six party cannons firing 50 times every second, of course!

BIG MACINTOSH:
M60E4 oyster.ignimgs.com/mediawiki/a…
Samuel Jackson had it all wrong. The AK-47 is NOT the weapon you use to "kill every motherf*cker in the room". Short of a grenade, the M60 is the best you can get. Introduced in Vietnam and made famous by Rambo, The Pig continues to kick ass to this day. For added fun, slip some 20mm grenades and 10 gauge shotgun shells into the belt. (they fit!)

OCTAVIA:
IZHMASH AKS-74U "KRINKOV" media.moddb.com/images/members…
One of the more ingenious entries in the long line of successors to Mikhail Kalashnikov's brainchild, the AKS-74U has all the compactness of a submachine gun, while retaining the punch of an assault rifle. Remove the magazine and it effortlessly fits in a violin case!

PRINCESS CELESTIA:
TAURUS RAGING BULL .500 MAGNUM static.comicvine.com/uploads/o…
A hand cannon for the highest class, this "pistol" takes the concept of practicality and laughs in its face. Make no mistake, it's still useful. This gun can bore a hole through an elephant at 100 yards.

PRINCESS LUNA:
FN HERESTAL FIVE SEVEN (SUPPRESSED) www.quiettime.us.com/nfa_img/1…
If ninjas packed heat, this would be their sidearm of choice. A favorite of spec ops teams throughout Europe and even some parts of the US military, the Five SeveN's combination of space-age materials, ingenious construction, and nasty ammo set it far apart from other pistols. Headshots aren't a priority with this little gun, as its 5.7mm rounds drill straight through body armor even with a suppressor.
