The Asgarn .50 BMG heavy machine gun is belt-fed, air-cooled machine weapon capable of semi-automatic and automatic fire. The Asgarn fires from a closed bolt at all times, and uses a short-recoil operated action with a vertically sliding locking block, which rises up to lock the bolt to the barrel extension, and drops down on recoil to unlock the bolt from the barrel. It also has a bolt accelerator, made in the form of a lever located at the bottom of the receiver. Upon recoil, once the barrel is unlocked from the bolt, it strikes the accelerator, so the kinetic energy of the recoiling barrel is quickly transmitted to the bolt, improving the reliability of the weapon.

It features a semi-direct gas-impingement system which by turning the gas plug from 1 to 6 increases and decreases the rate of fire of the machine gun by taking exiting gas from the barrel while firing and chanelling it to the bolt through reinforced gas tube,the gas plug system is also suitable (as seen on FN FALĀ“s) to increase reliability in extremely cold weather.
Barrels are screwed into the barrel extension and are not quick-detachable on standard Asgarn weapons; furthermore, once the barrel is installed in the weapon, the headspace must be adjusted prior to firing, or the weapon may fail to fire or produce a serious jam.The rear part of the barrel is enclosed in a short, tubular, barrel jacket with cooling slots,while the front part is fluted. The back of the receiver houses a heavily reinforced bolt buffer, and a special system of two additional buffers are used to soften the movement of the heavy barrel. On infantry guns, the cocking handle is installed on the right side of the weapon, but slots are made on both sides of the receiver for tank installations which may require a left-side cocking handle.

The Asgarn machine guns use a disintegrating linked steel belt, with the feed switchable from one side to the other through the re-installation of certain parts in the feed unit. The belt feed is of the two stage type – every cartridge is first withdrawn from the belt toward the rear by the pivoting extractor lever, attached to the bolt. Once the cartridge is clear of the belt, it is lowered into a T-slot cut into the bolt face, and pushed forward into the barrel. Spent cartridge cases are forced down the T-slot and out of the weapon through an opening at the bottom of the receiver by the following cartridges, or by the pivoting belt extractor lever (for the last cartridge case). A rotary switch is used to select the track for left or right side feed.
Since the gun fires from a closed bolt, it has a separate firing pin, powered by its own spring, and hosted inside the bolt along with the sear and cocking lever. Upon the recoil stroke of the bolt, the cocking lever pulls the firing pin back until it is engaged by the sear. Once the bolt is fully in battery (locked closed), a pull on the trigger raises the trigger bar so it acts on the sear and releases the firing pin. The standard firing controls consist of a push-type thumb trigger and sear release buttons located between the dual spade grips. Alternatively, an electric solenoid trigger can be installed for mounted vehicle applications.

The Asgarn has an unusual method of providing semi-automatic fire – it has a bolt latch, which locks the bolt to the bolt buffer in the open position after each shot. Therefore, if gun is fired in semi-automatic mode (single shots), for each shot the operator must first release the bolt forward by pressing the bolt latch release, located next to the thumb trigger (as the gun fires from a closed bolt). After the bolt is released and the gun is loaded, the operator may push the trigger to fire a single bullet. If the automatic mode is desired, the bolt latch must be turned off and locked by turning its lock to the left. In this position it will not engage the bolt and the gun will fire continuously as long as the trigger is pressed. Asgarn heavy machine guns feature, among other items, an additional manual safety located next to the trigger.

Standard sights consist of a Hensoldt Optical Sight with 7.5x augmentation. Optionally,folding blade front and frame-type rear sights can be mounted. In this case the rear sight is mounted on the receiver, the front sight is located at the front of the receiver and protected by an arc-shaped sight protector. Additionally, various types of other telescopic and night sights can be installed using appropriate mountings.

OOC: A good, solid design. Always nice to see a person who knows what he's writing about.
A couple other suggestions - if you use the Times font, it's best to add a size=3 tag, so that it is easier to read. Also, additional empty lines between paragraphs would help. "Wall of text" is the greatest problem with sales, the text should be readable even to someone looking at it casually.
BTW, I'd suggest to still link the old large image with a click on the small one. That will show detail for those who are interested.


The design itself is good and solid, so I'll get some at the storefront.

OOC: So what does the gas system actually do on this?

Are you basiclaly using a hispano mechanism where the gas just provides the unlocking impulse and the recoil the rest or is it something different?

aside from that it sounds like a reasonable M2 alike

OOC:Yes.It uses the semi-direct (semi-direct because some of it is bypassed and delayed by an heavier chamber in the tube,before it reaches the bolt)gas impingement system to unlock the bolt,hence the gas plug for extreme weather conditions.After the first shot,the backwards impulse of the barrel also has the function of "pushing" the bolt back,aiding in positive bolt unlocking and function.The rest of the firing mechanism works with the simple,softened recoil.

Thank you.
