Changes to the original design included the fire control and safety selector, whose lever was transferred to the left side of the receiver housing, the cocking handle cut-out in the bolt carrier assembly was covered with a strip of metal.

The cocking handle itself was placed at an upward angle (enhancing left-handed reloading), the rear sight assembly was installed on a sliding tangent with 150 and 300 m range adjustments[3] and the rifle was equipped with a folding tubular stock with a latch modeled on the locking solution employed in the SIG SG 540 rifle.

[5] Prior to the adoption of the RK 95, several Chinese and East German-based AKs were purchased by Finland to easily arm mobilized Finnish soldiers in the 90s.

[8] On April 18, 2023, it was reported that Sako made several RK 95s in a gold finish for export to the UAE in the late 1990s for the Amiri Guard.

[9] The RK 95 TP is a select-fire, gas-operated firearm using the Kalashnikov-pattern operating system with a long stroke gas piston rod coupled to the bolt carrier as in the AK rifle.

The RK 95 TP has a plastic-coated tubular metal shoulder stock that folds to the right side[5] and features an internal compartment used to store a cleaning rod.

[5] The rifle feeds from curved box magazines made of an impact-resistant polymer (empty weight: 0.16 kg), with a 30-round capacity of double-stacked cartridges.

[11] An export variant of the rifle was also produced, modified to use the 5.56×45mm NATO cartridge with the SS109 bullet, fed from plastic 30-round curved magazines.
