TSK standing for "taistelu kivääri" or battle rifle, the TSK is a .308 caliber Astronean service rifle . The TSK is heavy and has a long barrel, making it slightly cumbersome when compared to modern assault rifles, but features good erganomics and handling in comparison to other battle rifles. Accurate out to 800 metres and able to take down targets with a single shot due to its powerful caliber. This accuracy requires training to be taken advantage of, as the TSK is best fielded in semi automatic due to its high recoil in when used in full auto. One cannot simply "spray and pray" with an TSK. It is however very reliable, very sturdy and easy to clean.


The gas system is driven by a short-stroke, spring-loaded piston housed above the barrel, and the locking mechanism is what is known as a tilting breechblock. To lock, it drops down into a solid shoulder of metal in the heavy receiver. The gas system is fitted with a gas regulator behind the front sight base, allowing adjustment of the gas system in response to environmental conditions. The piston system can be bypassed completely, using the gas plug, to allow for the firing of rifle grenades and manual operation. The TSK's magazine capacity ranges from five to 30 rounds, with most magazines holding 20 rounds. In fixed stock versions of the TSK, the recoil spring is housed in the stock, while in folding-stock versions it is housed in the receiver cover, necessitating a slightly different receiver cover, recoil spring, and bolt carrier, and a modified lower receiver for the stock.

A variant named A2A1 LSW, meant to serve as a light machine gun in a support role, is also capable of automatic fire. Differences from the A1A1 include a heavy barrel, squared front sight (versus the "V" on the semi-automatic models), a handguard that doubles as a foldable bipod, and a larger 30-round magazine although it can also use the normal 20-round magazines as well.

The Astronean designated service rifle featured polymer and steel furniture in a black finish, shortening the weight of the weapon. In addition, the carry handle was removed. The weapon was restricted to semi-automatic fire in order to monopolize on the accuracy of the weapon and conserve ammunition.

The A1A1 saw service for half a century before being relegated for marksman roles as the AM series of rifles replaced the A1A1.

A1A1 Para[edit]

A paratrooper version, designed for the Light Infantry, used a folding stock instead of the fixed one in use with the primary A1A1 model, as well as a select fire capability that allowed for automatic fire. Light Infantry troops were considered elite soldiers, and as such were given extensive training in the use of marksmanship and rifle shooting. As such, they were more trusted to handle the automatic fire of the TSK, more so than the average infantryman.

TSK OSW[edit]

The favoured primary weapon of Astronean Tier 1 Special Forces,The TSK OSW (Operational Special Weapon) is a modernized variant of the Astronean TSK series of battle rifle, with lightweight aluminum furniture and a shorter barrel length. The OSW utilizes modern manufacturing techniques to create an affordable and effective combat rifle, up to par with newer competitors. Its large caliber round is able to place shots accurately at extended ranges, acting if necessary as a marksman rifle with relative ease. Superior ergonomics and materials also allow for better control in fully automatic sustained fire, something the original TSK struggled with. This allows the OSW to be utilized in a variety of situations
