TSNIITOCHMASH introduced a compact version of the machine under the cartridge 9h39 mm (sniper SP-5 and SP-6 piercing).
Borisov A.D. and VN Levchenko. based machine AS "Val" developed a shortened version, Names MA "Whirlwind" with index CP-3
Automation is based on the energy of powder gases, moved from the bore through the gas pipe to the piston bolt. Locking occurs by turning channel shutter five lugs. The trigger mechanism allows keeping both single, and automatic fire. High penetration bullet cartridge SP-6 provided the defeat hard targets at ranges up to 200 m. At this distance the CP-3 punches 6 mm steel plate preserving slaughtering actions for a barrier. Therefore provides reliable defeat targets in flak jackets 1-3 protection class, as well as in the vehicle. At a distance of up to 150 meters bullet pierce vehicle engine block.
Small dimensions and weight allow concealed carry CP-3 in a case. His bullet has a high muzzle energy, more 600 J., which, the large mass (16,1 gram) long retains its, providing reliable defeat of live targets at a range 200 m, far surpassing in this case by stopping power and penetration all similar models.
Magazine capacity is insufficient for short-range automatic weapons. Large slope of the trajectory complicates the choice of aiming point, especially when shooting at the maximum distance. Used cartridges are very scarce. Their large mass limits wearable ammunition.CP-3 is simple in design, easy to disassemble. The trigger mechanism allows single and automatic fire. Translator fire mode is located next to the trigger, it is possible to switch without removing hands from the fire control handle. Sufficiently large trigger guard allows you to shoot with gloves. Folding abutment shoulder increases the resistance arms. Automatic sufficiently robust and resistant to contamination.
The elastic deformation is not enough hard butt when firing bursts improves the dispersion of bullets. High rate of fire helps stem taking with line of sight and the rapid consumption of ammunition.
