With the decision to split the competition into weight classes, a request for submissions was put out.
The Substitute Standard Heavy Machine gun category had four promising entrants, with most entrants scared off by the weight restrictions.
As a reference for cost, the Arbatescu rifle is 1₮50, while the M.853 Holborn-Arbatescu Machine Gun is 45₮15.
The Cirno Machine gun is a relatively complex gas operated tilting-bolt machine gun. It is air cooled, belt fed, and as a result has a 18kg and 1040mm long gun body with a 711mm barrel. Specifications call for a 400 round per minute firing rate, which can likely be sustained for a minute or two at least although limited long term as the gun fires from a closed bolt somewhat negating the best efforts of the cast aluminium radiator. The tripod is significantly simplified from the standard model to try and cut 7.4kg (and just barely doesn't make it at 18.5kg,) and lacks gearing for elevation and traverse, as well as locks for either. Estimated price of the Cirno is 48₮120.
The Handel Schweres Maschinengewehr is an Irmionic-designed short recoil toggle locked system like most heavy machine guns, but is air cooled and fires from an open bolt at a blistering 550rpm. Thanks to some clever clever design work, the action is significantly lighter and simpler than the Holborn-Arbatescu, and uses a much heavier fluted barrel for cooling instead. This overall resulted in a 13kg and 1120mm long gun body with a 716mm barrel. The tripod is 17.9kg but is somehow even more bare-bones than that of the Cirno, and only has a two position height adjustment. Estimated price of the Handel Schweres Maschinengewehr is 43₮40.
The Mornay Maschinengewehr is particularly unique, being a screw-delayed blowback action, and managed to make weight with a lighter, compact receiver, to the point where without the 3kg of water needed for the jacket, it is 17.5kg with an 1100mm gun body and a 600mm barrel . Feeding is done with a rotary spool like some early Holborn models, and is relatively robust. The tripod is even lighter at only 12kg, but is just barely tall enough to allow the gun to feed reliably from a standard ammunition box, while also being effectively just a bare pintle mount without any forms of adjustment. Estimated cost of the Mornay is 42₮10.
Continuing the delayed blowback category, and rounding out the heavy category is Abram Topani's submission. The Topani Maschinengewehr is a toggle delayed blowback, relying on pure mechanical disadvantage to contain the cartridge until such time as pressure has dropped to a safe level. The cyclic rate of the action is 400rpm Not bothering to cut weight to the extent called for by the commission, the Topani has a 20kg body, uses 3kg of water in its water jacket, and is 1067mm long with a 527mm barrel. The tripod is also 20kg, but has tubular continuously adjustable height legs and geared elevation and traverse. Estimated cost of the Topani is 38₮149
The Manportable category, despite being subject to more stringent restrictions had a wider field of entrants at five.
Viktor Schneider, a veteran turned employee of a state armory, submitted an automatic rifle design based off of our current service rifle. The rifle uses a gas-operated piston running under the barrel to unlock and open the bolt, which is then returned to position by a spring contained in a metal enclosure behind the bolt, stripping another round from the top-mounted, detachable 32-round box magazine and allowing the firearm to cycle again. Further modifications to make the final automatic rifle design better suited for sustained fire include the elimination of some wooden furniture on the gun, a simple bipod, a finned barrel, and a modified receiver design to cover up the moving parts used to automatically cycle the rifle. Cyclic rate is 450rpm. Overall weight is 8kg and length is 1042mm with a 686mm barrel. Estimated cost of the Schneider is 35₮100.
The Handel Leichtes Maschinengewehr is an Irmionic-designed short recoil toggle locked system like most heavy machine guns, but is air cooled and fires from an open bolt at 550rpm. Thanks to some clever clever design work, the action is significantly lighter and simpler than the Holborn-Arbatescu, and uses a much heavier fluted barrel for cooling instead. This overall resulted in a 13kg without ammunition and has a 1120mm long gun body with a 716mm barrel. The Handel light entry is fitted with a simple bipod folding bipod, and replaced the butterfly trigger with a pistol grip and a buttcap on the back of the receiver. Estimated price of the Handel Leichtes Maschinengewehr is 39₮149.
The Montel Makina Fusila is a frankly unique concept for an automatic weapon from Euskadia. The overall action hurts to think about but can best be described as a short-recoil action, with a non-reciprocating, swinging breech block, fired from a closed bolt. The action is notionally capable of a fairly slow 360-400 rpm The overall weapon is quite light at only 10kg unloaded, and according to the documentation the heavily finned barrel and barrel extension can be pulled out out of the jacket and receiver and replaced with a new barrel fairly quickly in the field. The thirty round magazines of the Montel are notably simple, with the feedlips being actually integrated into the receiver. Overall length of the Montel is 1143mm with a 583mm barrel. Fairly uniquely the Montel can easily swap the bipod out for a pintle if needed for a specific role. Estimated cost of the Montel is 46₮130.
The Frankengatsch Leichtes Maschinengewehr is a long stroke gas-piston operated rotating bolt weapon. It has a 47 round pan magazine indexed by the action, and uses a cast aluminum radiator inside a shroud/flash hider to cool the action, necessitated to fire for any length of time thanks to its astounding 550rpm cyclic rate. The Frankengatsch is of roughly middling weight at 11.8kg and is 1283mm long with a 666mm long barrel. Otherwise descended from the Frankengatsch pistol, the action is reasonably complex with an adjustable gas regulator among other things. A bipod is mounted to the shroud allowing for ground firing, although provisions have been made for attaching a yoke to let the gun take advantage of a pintle mount if available. Estimated cost of the Frankengatsch is 49₮149.
The Balzac Portative is a Balkh-designed air-cooled long stroke gas operated weapon that fires from an open bolt. Uniquely for the competition the Balzac offers a semi-automatic firing mode as well as fully automatic. The Portative locks using a rotary nut mounted on the barrel extension which is operated by the piston, and locks into serrations on the bolt. Because of the unique offering of selective firing, the thankfully non reciprocating charging handle on the back of the action is also the fire selector, and is pulled back into where the stock would normally be to change positions. The Portative, like all Balzac guns uses a thirty round metallic feed strip for feeding, allowing continuous firing until the finned barrel overheats. With the unique small tripod, the Balzac Portative weighs only 12.8kg, although the tripod can be unlocked for further weight reduction or to use the yoke and pintle it rides on to mount it to a fixed position. Overall length is 1190mm with a 565mm barrel, and the cyclic rate on full auto is 500rpm. Estimated cost of the Balzac Portative is 45₮20.
With nine total weapons, it would be advisable to downselect in at least one category before handing a selection over to the testing team, but this is not a necessity.
