Unless our opposition gets into service rifles, I don't see a reason to revise our proven product right now.  I would like to a wildly different cartridge available for when we diversify into heavier weaponry.  We save money by doing it now.

Oh, fer those wondering, I have updated the Autogun proposal from 1912. Please tell me what Ive screwed up.
Quote from: Prykanbul AG-6-??
The AG(also known as the Autogun) is designed to dish out our 6x50mm round in job lots. Gas piston-operated and belt-fed from a contained spool(using a metal belt that adds to cost but improves reliability, and drawing rounds back out of the belt and then down to the breach. The spool itself is contained within a box mounted under the gun and holds 50 rounds, although longer lengths could be used.), the autogun is designed to be truly man-portable and used almost like a rifle, retaining the layout of one(with the addition of a pistol grip). It comes with a fire-selector for the ability to put out single shots and has a full-length 559mm quick-change barrel designed to take no longer to replace than it takes to reload. An integrated bipod capable of being positioned at either the gas block or the trunnion and large diameter aperture sights(with a smaller diameter flip-up leaf for precision work) graduated out to 800m bring the feature list to a close. The firearm's rate of fire is some 500 rounds per minute.
 Maximum weight is to be under 10kg and should be more along the lines of 8kg; cost should be less than 45 and more along the lines of 30.

How nerdy do you want to get?

Given how much our competition loves putting out cheap and unreliable POS, I'd include full accessories: an "oiler" oil can, cleaning rod, and most importantly one or two spare barrels specifically headspace'd for the individual gun.  (Even today, most machine guns have barrels are specific to the individual gun.  Adjustable headspace is a thing on the M2, but then you're making barrel changes slower as well as trusting privates in combat conditions not to screw it up.)

If you're going to do select fire, might as well do a safety setting.  Also, does the action fire from a closed or open bolt?  Closed is sexier, but an open bolt allows for easier cooling and prevents cookoffs.  In you go open bolt, you can always put a dust cover flap if you're worried about field grime.  While we're talking about action, a "last round bolt hold open" is a nice ergonomic feature to consider.

Which direction does the belt feed from, and which direction does the brass eject?  Assuming a solo right handed shooter, you want it to feed from left and spit brass to the right.  But if you want an assistant gunner, it might be more convenient to feed from the right and spit brass down (rather than left across the shooter's face.)  (Feeding from the bottom can make obstruct prone use, and top fed can block sights and general field of view.)

Speaking of assistant gunners, the problem with making a MG with changeable barrels is that there's no way in hell a solo operator can carry an MG, hundreds of rounds and a spare barrel or two.  They're called "crew-served weapons" for a reason.

Speaking of barrel changes, make sure there's an insulated (wood) grip/handle, or everybody is going to have a bad time.

The small diameter sight is kinda silly, but maybe some customer will like it.  RoF and belt size looks about right.  Other than being easier to carry, another nice thing about smaller belts is it keeps the operator from overheating the air-cooled barrel.  (Fun fact: Modern air-cooled MG's that go through 100-200 round belts are supposed to be getting their barrels swapped every 2 to 5 minutes.  This is why quick change barrels and two spare barrels are a major feature of GPMGs.)

30 credits seems pretty optimistic, but I guess we'll see, eh?

I actually removed a fair few accessories, namely the ability fer mounting volley sights, and dont feel that noting cleaning kits is really needed, while barrels would be up to the end user. Open/closed bolt firing is a point, might have it do open for full-auto and closed for repetition. If theres going to be a fire selector, I would assume theres a manual safety, but sure, thats easy enough to note... And yeah, I would generally assume that any MG is going to have assistants, at the least to carry(or collect) more ammunition. Heck, SMGs did for a while.

 Well , new turn, and since we lack the funds to get a handgun and ammo fer it and we dont want to use anyone elses ammo, I guess its autogun time.

The spool itself is contained within a box mounted under the gun and holds 50 rounds, although longer lengths could be used.), the autogun is designed to be truly man-portable and used almost like a rifle, retaining most of the traditional rifle's layout with the addition of both a pistol grip and a hand-piece on the stock. It comes with a fire-selector for the ability to put out single shots(also acting as a manual safety and fully ambidextrous) and has a full-length quick-change barrel(contained within a perforated stamped-metal shroud and exactly the correct length for optimum power from our fast-burning propellant) that is designed to take no longer to replace than it takes to reload and yet retain the firearm's headspacing. The firearm's bolt rotates to lock with eight locking lugs and fires from a closed position. The firearm is striker-fired.
 The firearm is capable of feeding from either the left or right(although changing from one to another is an armorer-level task) and spent casings are ejected out the front of the receiver. The firearms features include an integrated bipod based upon that of the SR/M-6-12 capable of being positioned at either the gas block or the trunnion, large diameter aperture sights(with a smaller diameter flip-up leaf for precision work) graduated out to 800m, a last-round bolt hold-open system, automatically-opening dust covers and drop- and out-of-battery safeties. The firearm's rate of fire is some 500 rounds per minute.
 A steel-tubing tripod is available for the firearm weighing in at 20kg and is designed to mount 250-round boxes of ammunition and integrated volley sights, along with settable stops for both elevation and traverse.
 Maximum weight of the complete firearm(including barrel) is to be under 10kg and should be more along the lines of 8kg; cost should be less than 45 and more along the lines of 35-40.

Prykanbul Manufacturing Automatic Rifle, 6mm, Pattern 1914 (AR-6-14)
The AR-6-14 is a new form of weapon, one that buyers have started considering and asking for, an automatic weapon that isn't so heavy that you need a team to move it, that can be fired from the shoulder on the move and used in any situation.

The barrel is made particularly short, as short as only our fast-burning propellant allows. Its construction is light, relying instead on its heat-resistant alloy to allow sustained fire. The barrels are also made to be easily changed to permit longer duration firing. This is accomplished by means of a carry handle on the barrel, which must be rotated forwards out of a slot on the side of the receiver, then used to rotate the barrel to unlock it. The slot ensures that the barrel cannot come loose with the carry handle still in place, since it cannot rotate until the carry handle is pulled out of the slot. There is a bayonet lug on the end of the barrel capable of taking the SR-6-11 bayonet.

The action is built around a long-stroke gas piston system, with the piston assembly below the barrel. The springs, distance of travel, and gas port size are tuned to ensure a relatively low rate of fire of about 400 rounds per minute on automatic fire but a fairly powerful action so that the weapon remains very reliable even in poor conditions. It fires from a closed bolt and relies on the barrel and changing system as well as its low rate of fire to deal with heat. The charging handle on the right side does not reciprocate, and includes a dust cover section that covers its own running slot. The ejection port is sealed completely by the bolt when closed. The mainspring is captive in the buttstock, and a metal guide rod on the bolt carrier is used to push against the spring. The bolt carrier runs on two substantial rails cast into the receiver body, which allows the back plate of the receiver to be integrated into the wooden buttstock and hinged, allowing the whole action to come out of the gun in one piece (basically the FN Model D BAR). The bolt is locked by rotating similar to a regular bolt-action rifle, except it is forced to rotate via a cam in the bolt carrier rather than a soldier working the bolt directly. The whole receiver is cast and then machined to the final dimensions, saving a lot of machining time and therefore a huge portion of the cost but trading off strength, as a casting will almost never be as strong as a regular milled component. However, our metallurgical knowledge can offset this enough to allow the casting to be strong enough. The full-length rails and use of a spring long and strong enough to force the action to come to a complete stop without any impact both reduce wear and stress accumulation points.

There is a detachable bipod mounted to the bottom of the gas block, made out of a durable steel but generally as light as possible while still giving the weapon a stable firing platform. The bipod allows some left/right traverse. This allows the weapon to have a bipod mounted forwards of the center of mass, far enough forwards to give good stability and controllability, without requiring each barrel to have a bipod, or to have one detachable bipod switched between barrels. The magazines hold 30 rounds and are attached to the bottom of the rifle. They're double-stacked and double-feed, and most importantly are not disposable and instead are built to be durable and always reliable, built of tough steel.

There is a selector lever integrated into the fire control group that allows the user to toggle between automatic and semi-automatic fire. There is a separate simple safety that locks the hammer in place when it is engaged, preventing it from being dropped intentionally or accidentally. The sights are the same as on the SR-6-11. It has a separate wooden pistol grip and stock for better control when not firing from a supported position.

The combination of bottom-mounted mags and detachable barrels (detached from the right side of the weapon) mark this as a combination weapon. It must be reloaded by the gunner himself, and is easy for him to do so, but an assistant gunner can easily be added to the team allowing for more barrels and ammunition to be carried, thereby allowing for sustained fire. With one gunner this weapon acts much like an automatic rifle, with a team it can be pressed into the light machinegun role as well.

Okay, trying to forecast this turn again.  FR's MG isn't the garbage it used to be, but it was rejected for the Cro autorifle contract for still being a full size MG.  I don't see a way they can fix that with a revision.  They probably should focus on the IRA MG contract.

Behrens is in an interesting position.  The bank contract is a gimme for their original shiny pistol, especially because no one else is getting into pistols.  But they do have two lines and 20 creds for a design.  They could make a cheap blowback SMG.  It would open up a lot more opportunities going forward. A compact or suppressed pistol would be a sure thing short play though.  Though they could also throw good money after bad revising that machine pistol.

That being said,  I see the Wiel B and Behrens SMG/MP going for Crovern again.

The bank contract is a handout for Behrens.

Under the two contract rule, Behrens may throw a pistol at the Royalist assassin's if they make an assassin pistol or their SMG/MP rolls terribly enough to skip the Crovern bid.

For the IRA MG, FR is definitely going to go for this.  Question is only if they're doing a new design/revision for it.

All that said, we're pigeonholed with that 6mm rifle cartridge.  It's too small for a proper MG, but too large for a blowback SMG.  The Crovern contract is where we should focus.

Therefore, I'm leaning more towards Madman's autorifle.  The Wiel got rejected for being too big and AH's autogun seems to be headed in that direction.  It seems more towards the IRA MG, but again we don't have the best cartridge for a machine gun nest.  Furthermore, the belt-fed reversible action which can be fired as both open or closed bolt sounds pretty dodgy.  The  IRA explicitly want something reliable, and that doesn't sound like it would be.
