ICS Airsoft got a competitor to the Tokyo Marui MK23 SOCOM NBB Pistol to match it for its stealthiness. Alexander of Red Army Airsoft tries to find out if the claim is true in this video review (in Russian with English subs)... "PM-2 from ICS claims to be the competitor for MK23 Socom. Moreover, a 'pro-Russian competitor,' which whets appetite to this product in Russia.

The main minus of MK23 Socom is its size, it is huge and not the most convenient to carry.

PM-2 from ICS is noticeably more compact, doesn't have a blowback, has a higher velocity and can work at lower temperatures, because it works from CO2.  

According to the manufacturer, the PM-2 is quiet, due to the silencer, and shoots far due to good hop-up. We will definitely check this out in this video."
