Rifle design: VL M187x50mm Ammunition
The Vaux and Leander Manufacturing’s VL M18 (not to be confused with the ’18 or the G18 or the other M18) is a ten-round straight-pull bolt action rifle for standard infantry use. In order to fit a ten round internal magazine, it extends vertically through the bottom of the rifle next to the trigger guard. The magazine is prone to mis-alignment, resulting in an internal jam if dropped or jostled.
The M18 uses a straight-pull action. This means the user does not need to lift the bolt or lock it back down, simplifying the action and increasing firing speed. The M18’s straight pull action does leave a little to be desired, however – the user must be certain the action is all the way forward before firing or the rifle may experience an out-of-battery fire. In this case, the rifle can be damaged or even wound the user, and the stiff nature of the M18’s bolt makes it difficult to be certain it’s fully forward without visually checking. The accuracy of the M18 is sub-par, though the reason is as-of-yet unclear. Though it won’t be winning any sharp-shooting awards, the VL M18 can reliably hit a man-sized target at up to 300m or so. The rifle can be field stripped with some difficulty, as the straight-pull bolt is reluctant to leave its housing and testers often resort to using leverage to pull it free.

Revision: VL M18 A1Rifle: VL M18
Gunsmith engineers adjust tolerances on the straight-pull bolt of the M18 (no, the other M18). The bolt slides much more smoothly now and it's obvious once it reaches all the way forward - though it is still possible to fire out-of-battery if the bolt isn't seated all the way forward for some reason. The bolt can be removed without the use of leverage now, assuming the user knows what they're doing.
No price change.
VL M18 A2Minor flaws noted in the rifling are likely the cause of the VL M18's poor accuracy - particularly near the muzzle, where the rifling simply...stopped. The rifling is improved and the barrel is lengthened slightly, giving the weapon accuracy comparable to most major rifles of this era. The extra attention to performance and material slightly increases the M18's expense.

VL M18 A3SScopes are a bit of a shift from gunsmithing. After some discussion and preliminary designs, we conclude it's cheaper to create a mounting rail alongside the main action and purchase some after-market scopes. The scope is off-set from the barrel, which isn't great for sharpshooting but means the spent brass doesn't have any risk of hitting the scope. The scopes are a bit expensive, increasing the cost of this variant of the weapon.

rifle: VL M18 B3
finally getting around to making changes to the action to prevent the gun from firing if the is not fully closed.
The firing pin now features a safety (a small internal lever which pushes up against the chamber) which requires the bolt to be fully forward before clicking off. This should prevent the weapon from being able to fire before the bolt is fully seated.
It's a small piece and non-complex, so the cost of the weapon does not change appreciably.

Design: Machinegun VL mg21 A1
7x50mm Ammunition
The VL mg21 is a belt fed machinegun chambered in 7x50mm, and operates with recoil action. To keep the weight down the machinegun is air cooled, in order to ensure sustained fire it has a heavy barrel and a barrel shroud to help disapate heat. Additioanly the barrel is designed to be quick change to ensure that once the barrel does over heat a machinegun crew can quickly replace the barrel with a fresh one instead of having to wait for the gun to cool down. The mg21 come with two mounting points one at the end of the barrel shroud too attach a collapseable bi-pod and one at the bottem of the reciver for mounting the gun on tripods and emplacments. Much like the VL M18 the mg21 come with an adjustable sight that starts at 50m increments by 50 up to 400m. The reciver is designed to be somewhat spacious to make it easier for the guuncrew to access the internal components for ease of maiintenance.
Overall the VL mg21 is designed to be a somewhat light machine gun that is man portable and somewhat easy to maintain on the field.
Machinegun VL mg21 A1The smallest caliber machinegun to come out of Occassio yet, the VL mg21 fires 7mm belt-fed ammunition. The weapon is recoil-operated, which means the entire barrel rocks back with each shot in order to cycle the action. The moving barrel gives the weapon a stiff penalty to accuracy, but this type of action is fairly common and not difficult to pull off. The weapon is air-cooled, so the barrel is designed to be quick-swapped once heat buildup has become an issue. A simple bipod keeps the muzzle elevated, and the sights are standard ladder sights going up to 400m. The receiver case is large and held together with simple clasps - not particularly elegant, but easy to access.
Separating the barrel from the heat shroud proves to be a bit tricky - initial designs don't specify much in how the quick-swap is supposed to be performed, and conflicting design schematics result in the bipod, barrel, and shroud being one whole piece. To swap the barrel, the entire front-end is unlatched and then unscrewed. This is quite cumbersome and awkward, and the new barrel must also come with its own shroud and bipod. This, obviously, increases weight. Additionally, if the barrel gets too hot before it is swapped, the tight tolerance in the screw threads will cause it to bind and become stuck, making it impossible to quick-swap altogether.
The belt is simple canvas with rimless ammunition. If the round slips too far forward or back in the canvas belt, it will cause the weapon to jam. The mg21 does not have a box magazine, and relies on a second operator to "smooth" the feeding process. It's not a particularly accurate weapon, and repeated heat warping can cause the lid of the belt feed cover to not close correctly.
Cost: $33 per Shipment Revision: VL mg21 A1.1
work is done to rework the receiver of the MG21 to make use of disintegration belt instead of a fabric belt.
Revision: VL mg21 A1.2
rework the gun body firstly adding bit more material into the feed cover to make it more rigid, secondly mounting fixtures are added to the side of the machine gun to allow for an Ammo container to to attached. finally the bipod is now to be attached to the front of the gun body instead of the barrel shroud, the shroud will have a catch at the bottom to hold the bipod when it folded.
Revision: VL mg21 A1.3
reworking the quick release to use locking lugs instead of normal screws which should resolve the issue of the threads binding when over heated. The latch is still retained to ensure the barrel does not rotate out of position during operation.
Revision: VL mg21 A2
VL mg21 A2 consolidates all of the above revisions into one design
The VL mg21 A1 features a number of revisions this turn, rapidly improving the weapons capabilities.
The fabric belt is discarded in favor of relatively new disintegrating links. These mechanical links fall apart once the round is removed, and are discarded along with spent brass. This requires the mg21's feed system to be redesigned, and it now will no longer be compatible with the previous canvas-based belts. This minorly increases cost.
The bipod is moved back to the gun's body, meaning the weapon now pivots closer to the center rather than at the muzzle. It can be collapsed and clipped to the forward shroud for easy storage. Adopting a box magazine and reworking the feed cover would require their own revisions, unfortunately.
The barrel no longer screws into place, but instead uses quick-locking lugs. The latch ensures it will not come lose unless disengaged.
Testing indicates the new lugs will not bind during temperature changes.
These changes are all unified under one name: the VL mg21 A2.

8x25mm VLP
The P24 is a closed-bolt SMG chambered for the 8x25mm VLP cartridge and using a 30 round double stack box magazine which is loaded from the bottem. In order to manage the rather powerful pistol cartridge with out requiring a heavy bolt assembly the M24 uses a lever delayed blowback action. To keep cost down much of the gun is made out of stamped metal with only the barrel, bolt, action and trigger assemblies being milled steel. With our experience with the VL mg21 some attention is placed on ease of maintenance though instead of latches the reciver housing using push pins to hold it together. In terms of furnation the SMG has a pistol grip and a strait vertical fore grip as well as a non-collapseable matal stock. The P24 comes with an adjustable aperture sight which can onlt be set between 50, 100 and 200 meters. the Gun has a 25cm barrel and and overall lenth of about 75cm.
the 8x25mm VLP is a 8mm catridge similar to the 9x25 Mauser
An actual honest sub-machinegun, the "Sub-machinegun VL P24" uses 8mm cartridges in a double-stack box magazine. Most of the furniture is stamped metal, including the collapsible stock. This is simpler to produce than wood, but a little heavier and is missing that at-home touch. The assembly is simple to disassemble and clean, which is a nice bonus, and is simple and easy (and fun!) to use. The 8mm cartridge has decent stopping power for relatively close ranges, too.
The closed-bolt is kept shut with a lever-delayed blowback action. The bolt resets the hammer, ejects spent brass, and scoops a fresh round into the chamber each time the action is cycled. The lever-delay can become jammed if the gun is cold, and accuracy past 50m is a bit of a dream - even if the aperture sights go out to 200m. This accuracy is despite the rate of fire, which is only around 200-250 rounds per minute. Furthermore, for no discernable reason, approximately one-third of all VL P24's produced will fail to fire after the first round. What's more, it doesn't even happen every time - for the guns that experience this failure, it happens randomly, about half the time a new magazine is sorted. These guns can be sorted out of our finished production with some careful testing, but this means our manufacturing cost is necessarily 33% higher.
It does look iconic, however.

SMG: VL P24 A1
This revision is a redesign of the action firstly to try and fix issues with some guns being unable to fire after the first shot, this will be done by making some adjustments to the trigger mechanism and bolt assembly to ensure that the hammer sear and firing pin can reset when the action cycles and released when the bolt is closed and trigger held down.
The firing pin and hammer sear are shifted further back, which gives it a slightly further distance to travel. This inertia allows the weapon to overcome a slight stiffness that occurs in one-sixth of our weapons.
As it turns out, this stiffness is due to whether the magazine is initially right-stacked rather than left-stacked, and only for weapons produced by our third assembly line. A minor variance in tolerances in this production line causes the pin to stick in place after the first round is fired. We discover this defect after completing the revision, but as it doesn't increase the cost of the weapon anyways it's not a big deal.

SMG: VL P24 A2
this revision is targeted at making adjustments to the tolerances of the gun assembly to prevented the lever-delay jamming on cold weather.
Rapidly becoming the most popular weapons manufacturer in Occassio, Vaux and Leander spends some time revising their new sub-machinegun's novel lever-delay jamming. The B series had gone for a swap to a straight blow-back design, which improved the weapons ruggedness, but the lever-delay version is clearly the superior as it enables higher rate of fire and lighter internals. Some small changes to the alloys used in the lever-delay mechanism enable different expansion/contraction rates at different temperatures, which should help the weapon maintain relative tolerances at either end of the heat spectrum.
Revision: VL P24 A2
SMG: VL P24 A3
work is done to improve the accuracy and effective range of the P24 by taking a look at the barrel and see if we can improve the rifling.
The grade on the rifling is steepened, giving the bullets more spin. Previously they would be prone to tumbling during flight, which was difficult to notice when your targets were shredded confetti.

Revision: Sub-machinegun VL P24
SMG: VL P24 B1
This is the plan B incase we are fail to fix the issue with some of our guns being unable to fire after the first shot. the plan for this revision to replace the closed bolt lever-delay blowback action for an open-bolt straight blow back. to ensure safe operation the bolt will be heaver stringer recoil spring are also installed. Notches are added to the main opening to serve as safeties by holding the bolt handle, one notch to hold the bolt closed and another hod the bolt open.
The bolt is swapped from a lever-delay blowback to an open-bolt straight blowback. This requires a slightly heavier recoil spring, and makes the weapon slightly more resilient to jamming due to dirt.
