Actually, 6.8 mm Has Just officially replaced 5.56 as the official Military round for assault rifles and carbines : - ).

LOLZ

Well, you cant say every marine, navy and air force member got the new Barret AR fully loaded with 6.8mm rounds.

Because that would be like, very hard and very expensive.

The 6.8 mm Remington SPC (or 6.8x43mm) is a rifle cartridge that was developed with collaboration from individual members of US SOCOM.[2] Based upon the .30 Remington cartridge [3], it is midway between the 5.56x45mm NATO and 7.62x51mm NATO in bore diameter and velocity. It is particularly adaptable to current 5.56 mm NATO firearms, the cartridge overall length being comparable.
Though ballistically similar to the 1950s-era .280 British, improved propellant powders allow the 6.8 mm to have a smaller case. The 6.8 mm SPC (Special Purpose Cartridge) has a muzzle velocity of 2,625 feet per second (800 m/s) from a 24 inch (606.9 mm) barrel using a 115-grain Hornady OTM bullet.[4]



------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------


Development:

The 6.8mm SPC cartridge was designed to address the deficiencies of the terminal performance of the 5.56x45mm cartridge currently in service with the U.S. Armed Forces.[5] The cartridge was the result of the Enhanced Rifle Cartridge program. Participating in the program were U.S. Special Operations soldiers, as well as armorers and other technicians from the United States Army Marksmanship Unit.[6] The development of this cartridge is remarkable in that it was designed by actual shooters in the armed forces, instead of by industry professionals. The goal was to create a cartridge that would bridge the gap between 5.56mm and 7.62x51mm, something that would perform similarly to the Soviet bloc 7.62x39mm AK-47 cartridge.
The program started the design by using a .30 Remington case, which was modified in length to fit into magazines that would be accommodated by the magazine wells of the M16 family of rifles and carbines that are currently in service with the U.S. Armed Forces.[7]
In tests, it was determined that a 6.5mm projectile had the best accuracy, but a 7mm projectile had the best terminal performance. Further tests showed that a 6.8mm projectile was the best compromise between the two, providing accuracy, reliability and terminal performance up to 500 meters. The combination of the cartridge case, powder load, and projectile easily outperformed the 7.62x39mm cartridge, with the new cartridge proving to be about 200 feet per second faster.[8] The resulting cartridge was named the 6.8 Remington Special Purpose Cartridge due to the size of its projectile and the fact that it was based on the .30 Remington case.
In general, adapting an AR-style rifle to the new cartridge only requires the replacement of the barrel, bolt and magazine of the 5.56mm-chambered rifle but to further streamline and simplify the conversion process many parts manufacturers sell complete upper receiver assemblies chambered for 6.8SPC alongside their conversion kits focusing on the key individual parts. While a complete 6.8SPC assembly is a somewhat more expensive route, the conversion of an existing 5.56mm/.223 rifle to 6.8SPC using a complete upper assembly takes less than a minute on an AR platform rifle without the need for specialized tools or skill. In contrast, when swapping out the individual component parts a significant level of gunsmithing experience, special tools, and time generally are required to detach the barrel from the rifle's upper receiver and the gas system, and conversely those same needs are required for the reassembly of the upper receiver with the new 6.8SPC barrel.

Performance:

The 6.8 mm Remington SPC was designed to perform better in short barreled CQB rifles after diminished performance from the 5.56 NATO when the AR15 was changed from the rifle configuration to the current M4 carbine. The 6.8 SPC delivers 44% greater energy than the 5.56 mm NATO (M4 configuration) at 100-300 meters. The 6.8mm SPC is ballistically inferior to the 7.62x51mm NATO cartridge; however, it has far less recoil, is considerably more controllable in rapid fire, and much lighter, allowing operators to carry more ammunition than would otherwise be possible with the larger caliber round. The 6.8 mm generates around 1,759 ft·lbf (2385 J) of muzzle energy with a 115 grain bullet. In comparison, the 5.56x45mm round (which the 6.8 is designed to replace) generates around 1325 ft-lbf (1,796 J) with a 62 grain bullet, giving the 6.8mm a terminal ballistic advantage over the 5.56mm of 434 ft-Ibf (or 589 J). In recent developments (the period 2004-2008) the performance of the 6.8SPC has been increased by approximately 200 ft/s by the work of one ammo manufacturer and a few custom rifle builders using the correct chamber and barrel specifications. The velocities obtained now from an 8" barrel are equal to what a 16" barrel was producing 4 years ago and the 16" barrel velocities are equal to what a 24" barrel produced 4 years ago using the data below. By increasing the velocity of the ammo 200 ft/s the range of terminal effectiveness has been increased approximately 100 yards or an 8" barrel now has the same effective range as a 16" barrel had in 2004 as the 6.8 loses apx 25ft/s/inch. -SSA website and 6.8 Performance test verified[9].
There are 2 standardized, but different, chambers for the 6.8 SPC which yield different results. Only the rifles chambered with the newer specified chamber and the slower barreling twist rate can safely use the higher powered/higher pressure ammunition. All other rifles should only be used with the standard cartridge pressure loadings.

Commercial Sales:

For hunters, the 6.8 SPC cartridge is a significant improvement over the 5.56mm and .223 cartridges currently available in the AR-15 platform. The latter cartridges fall below .243 of an inch, which is what many states have chosen as the smallest caliber legal to humanely take medium sized game such as deer. By adopting 6.8 SPC, a hunter gains the ability to use the versatile and ergonomic AR-15 platform for hunting.

Military use:


There is confirmed adoption of the caliber by the U.S. military.
Several law enforcement agencies Major and small,have adopted this caliber due to its strength.
In 2010 the Jordanian state-owned arms manufacturer KADDB announced that they would be producing 6.8mm rifles and carbines for the Jordanian Army.

Guns:
Semiautomatic action
The first major manufacturer to offer a 6.8 mm Remington SPC chambered version of the AR-15 was Barrett Firearms Company, offering the Barrett REC7. By 2007, most major manufacturers of AR-15 type rifles for the civilian gun market, such as Bushmaster Firearms International, LWRC, DPMS Panther Arms, Rock River Arms, and Stag Arms were also producing 6.8 mm Rem SPC carbines. Ruger Firearms produces a 6.8 mm version of their popular Ruger Mini-14 series carbine. [11] The Stag Arms Hunter and Tactical models utilize the newer chambers and specified twist rates to accommodate higher pressure loadings. Microtech Small Arms Research offers their version of the Steyr AUG in 6.8. Robinson Armament offers the XCR-L in 6.8, which can be easily converted between 6.8, 5.56, and 7.62x39.
Manual action
Remington also makes a bolt-action rifle chambered for 6.8 SPC, a 24" barrel Model 700. Ruger offers their M77 Hawkeye Compact rifle with a 16.5" barrel weighing in at 6.0 pounds. Browning offers their A-bolt rifle in 6.8 SPC, and Thompson/Center offers barrels chambered for 6.8 SPC for the G2 Contender and Encore.

Are you kidding me?! no blonking way im going to read that giant block of letters... what are you trying to say?

same here, tl;dr version

What Im saying is,The 6.8x43mm Cartridge Is Just as readily available as 5.56mm or 7.62mm ammunitions.
And That The M16\M4 configuration and receivers are COMPLETELY adaptable with the 6.8 mm assault rifle receivers and configurations.

So yes, The 6.8 is extremely COMMON.

As far as i know, this game is set before this gun was made, so no, i dont think its so common

i think it would be epic if you get an oxygen tank and a lighter and turn them into a heavy duty flame thrower.

That would Be COLD HomeBoy Good Idea! Same with spraypaint and a lighter.Thats Cool! Carl Mane Why Do you always have something smart allecky to say? Cmon Mane Just accept that the gun should be in the frakken Game!

Because im mean

And, you know its true

^ COLD, Mane and Mane again

also "frakken" is a "improvised" word for "fucking"

WoW....I never did like the look of WoW....after what Seth said, I like the sound of it even less.....ZP has a better WOW factor!!!

Cheers

XenaMorphed

..... Please Just Accept the Barret REC7 Into the damn game, It can use 5.56 Or 7.62 Or you Can make 6.8 I don't Care But I BEG OF YOU Let us Have the Piece Of Gold Known As The Barret REC7 (M468)!

I Will DONATE!

Behold the Taurus Raging Bull.

With .454 Casull ammunition (.44,45,or .50) It Is stronger than the SW 500 Because Of High powered armor piercing Steel Cored rounds.The Ragin bull Is A very Heavy,Bulky Revolver Weighing In at 3.8 pounds.But makes Up for It In Sheer Power And accuracy. Damage 9-16 Price $4000 Sell value $2500. Please allow this gun into the game.

Specifying ammo is a problem, and if you want guns in the game really really, you should use the Beta Feedback.

I did Use the Beta Feedback. Also,

An Image For the SW M500.

The Taurus Judge is in the game, if a little wonky with it's coding; I've yet to see satisfactory revolvers placed in it :l

Link: M110_Semi-Automatic_Sniper_System
it's an army new replacement for m24, which is already in the game
it would be nice to add new generation of the weapon

Link: M21
Link: M25
sniper rifles based on m14, already in the game

Link: M4
not sure vltor casv m4 is the same, but i would like both m4 and m4a1 (with full auto) included in the game
also there is a handy picture with attachable accesories there

ahhhh the slow motion cumshot (err i meant gunshot)

it will be wise to add more guns and ammo types in the game, but in later stages of the game...what we really need tho is an armor piercing sniper rifle that takes a large enough ammo type to make bowling ball size holes in the zeds ..or maybe even bigger... hehehe

Link: M590A1
not sure if already in game under different name
Link: M870
another one
Link: M1014
looks like franchi shotgun, but not sure
Link: MP7
uses 4.6x30mm ammo, exclusive to the gun
all are officially in use by the us military, they should be found inside humvees and military trucks

Remington 870: very normal shotgun, think its under the name... Police Shotgun xD

Benelli M4: as far as i know is not in the game, would be nice with a 2 round burst, as its semi auto, kinda looks like the "Franchi Shotgun" already in the game.

Heckler & Koch MP7: not very common, but common enough to be found everywhere, very nice little 9mm gun, lightweight, small, and powerful enough for zombie killing.
Mossberg 500: under the name Shotgun

No the MP7 is not used by the Military..

Beneli M4 Super Nova yes It looks like Franchi.

Mossberg and Remingon are already here.


theres no .40 Weapons and it is an increasingly popular round used by law enforcement, the military and criminals alike.

I also dont like a beretta, too inaccurate,poor processing and not made in germany

H&K blows.

That is all.

Liars gonna lie.

The military has indeed been looking at the 6.8, but they aren't making any decision on it any time soon, and MUCH LESS fielding the round in any number. It's like when people saw an add in the newspaper or on Guns and Ammo about how the military was testing out the XM8, and said "OMG the military switched out their crappy M16s and to this HK-made piece of AWESOME!!11!1one!1"


As it turned out, the XM8 completely sucked ass, and they denied it.

Also, go on to gunbroker.com. Go to "ammunition".

Type in 5.56.

Then type in 6.8.

See the difference?

The 6.8 round is a good idea, just nowhere near as popular as you make it out to be.

How about a blunderbus?

You know, those old trumpet-muzzled black powder guns that you could load with chunks of pretty much anything you wanted?

You could use broken glass bottles for ammo!

I will also use beta feed back to post.

M14/varent w 3-round burst setting. Just to add veriety to the rifle section, the Glock 18c is the single burst pistol so I figured it would be nice for rifles to have one.

Multi barreled shotguns(more than 2) These gems of guns are called Drillings(3-barreled),vierling (four barrels), and prepare yourselfs funfling (FIVE barrels) that have multiple rifle or shotgun barrels. I wouldn't imagine the trouble to program a gun with shotgun and rifle barrels. If the developers got the brass balls to do so, You have my support all the way. However, these guns are made with matching barrels too. Who doesn't want a 4-barrel .12ga or 5-barrel 7.62?!?!

I've only managed to see two and at the very same gun show, they were Beautiful.

http://www.hoferwaffen.com/hofer_52.php?lang=en
Copy and paste, and prepare to be amazed.

4 barrelled shotgun, ftw

How about the High explosive-fragmentation rounds for the AA-12 or 12ga. in genral? They would ensure shotguns will be used by high level players. You don't want everybody running around with PKM's and Barrets do you?

Turn that quad shotgun into a quad rocket launcher!
