Thanks to the success of the previous series, APS continues to develop the Phantom Extremis Rifles series providing more variants on the market leading to the new PER MK V version. The rifle inherits all the advanced features of its family. For example the quick spring change, the M-Lok handguard, the ergonomic grip, fire selector, magazine release and ambidextrous arm lever. APS did not limit itself to this by adding to this weapon some advanced components such as rs-2 stock and fiber optic sights.

The Phantom Extremis MKV is equipped with a special flash hider called "Sound Blaster". This sound amplifier increases the noise produced during the shot to intimidate the opponent.

Thanks to the success of the RS-1 version, APS has further developed the line of kicks by switching from RS-1 to RS-2. Like its predecessor it is built in military grade polymer, increasing stability and robustness. The stock is reduced to a minimum to reduce weight but still allows you to comfortably house the battery and the compartment can be opened without the need for tools.
