The Richeleau Model 10 (R-10) bolt action rifle was the mainstay of the Araean Armed forces for years. However during the outbreak of organized hostilities against Araea's natives - the sentient maniraptoran skrykes - the R-10 was found to be unwieldy in the kind of close quarters fighting in dense cover that typified engagements with skrykes. A shortened "carbine" version was widely issued as a stopgap measure. Shortened R-10s had already been issued to Araean cavalry units for some time and the design was adopted for infantry use as the R-10 "bush rifle" While the reduction in barrel length made the weapon more manuverable it did not solve the issues of low magazine capacity and slow manual operation - shortcomings that often proved fatal when facing a swift and agile opponent like a skryke. Small arms standardization went out the window during the early part of the war. Commercial lever action carbines and police riot shotguns were rushed to frontline troops and several prototype autoloading rifles were fielded with varying levels of success. Later on, submachine guns were added to the mix as well. Though used in ever decreasing numbers as the conflict went on, the R-10 was not officially retired as standard issue until the formal adoption of the KG-35 battle rifle. fav.me/d3jvu6f
The Araean army continues to use scoped R-10s as sniper rifles and even recently developed a refined and accurized version as their latest issue precision weapon. Surplus R-10s is still very common in the hands of rural police and civilian, and it's rugged action has been the basis for many commercial sporting rifles in various calibers.
One example of the many sporterized R-10 variants is the Kirscher KS-6 Ranch Rifle. The KS-6 is a essentially a surplus R10 action, but rebuilt by the Kirscher Design Bureau in 5.9x43mm and using a detachable synthetic magazine similar in construction to that of the KP-60 assault rifle fav.me/d3k40j3
. The stocks on the KS-6s were skeletonized as well, for weight savings and probably to give the weapon a racier look to appeal to customers. Kirscher marketed the weapon as a general purpose rifle suited for small to medium game hunting and defensive use (armed gangs of bandits are common in some regions). However most of the citizenry dwelling in the frontier regions tend to prefer Kirscher's autoloading rifle designs - the KG-35 and KP-60 for this role instead. The KS-6 has found favor among some customers due to it's simplicity and low pricetag however.
