Kb.1920 Series

Description
The Karabin 7.92mm Model 1920 or Kb.1920 in short. In translated form, Rifle.1920.

Unlike it's total failure of a "predecessor", the Kb.1917, the Kb.1920 was meticulously made throughout all stages of the design process. The end result of this was a very reliable, effective and accurate rifle capable of being used in essentially any role without obvious downfalls. The rifle was, as a result, seen as an extremely valuable piece of a soldier's kit. In fact, the rifle was received so well by the Uswan Armed Forces that it was affectionally nicknamed, "Poski's Wonder Rifle". The rifle itself had a slightly increased capacity than what was standard at the time, having a 6-round internal magazine which was loaded with a singular charger clip. This allowed the rifle to have a slight edge over competitors in terms of ammunition capacity without any noticeable difference in weight. The rifle's iron sights were accurate up to a range of 800m and the bolt-cycling was found to be fast and easy due to the light weight and oiled steel allowing for quick followup shots in the event one was needed. The rifle came with a wide assortment of attachments including a rifle grenade launcher, a 2.5x, 5x or 8x telescopic sight, a suppressor or a bayonet. The Kb.1920 was a pioneer for increased infantry firepower as it was the first rifle in Uswan service that was able to fire rifle grenades. This feature gave it the renowned ability to launch either high-explosive or smoke grenades at distances far exceeding the throwing range of an infantryman.

However, even the Kb.1920 had it's downsides. Rather than using an already widespread caliber, Jakub Poski instead decided to use his personally designed 7.92x58mm Płameń round which was specifically made in such a way so as to pack as much of a punch as possible while also keeping recoil manageable and the rifle lightweight. This caused an increased logistical strain when the rifle was first being issued as both the rifle and the ammunition had to be delievered to units.

Overall, the Kb.1920 passed all of its tests with flying colours and was accepted by the Uswan Military as the new service rifle for all branches.

History
The Kb.1920 and the majority of it's variants were an extremely succesful rifle series made in 1920 by the then, relatively new competitor to the firearms market, Poski FM. The rifle was designed out of a need for a "universal rifle" that would standardise manufacture, ammunition and equipment as a whole to fix the collapse of Uswan logistical systems as they were overburdened due to the astronomically high amount of different calibers and pieces of equipment in service at the time.

The Failure of the Kb.1917
The need for a universal rifle was supposed to be remedied back in 1915-17 with the introduction of the Kb.1917. However, due to a number of factors including lack of experience and desperation, the Kb.1917 turned out to be a complete failure. The 7.53x54mm Ministry cartridge which it was chambered in was notorious for jamming and being unreliable in general and the accuracy was appaling, with only 12 out of the 33 rounds which fired correctly hitting a man-sized target at 500m.

The rifle was only adopted as a stopgap while a better solution was being developed, this solution would eventually develop into the Kb.1920.

Legacy
The Kb.1920 was a breakthrough in terms of rifle designs. The rifle was a revolutionary design that incorporated many aspects of firearms designed prior to it and set the standard for ones designed in the future. It was successful enough that the Uswan War Cabinet didn't believe it necessary to design a new rifle and instead simply upgraded and modernised the tried and true design in 1935, resulting in the Kb.1935.
