Mach Sakai is the next reviewer we have noticed to review the Bolt Airsoft MP5J BRSS, or what Bolt Airsoft officially calls the the Bolt SWAT. This has the Bolt Recoil Shock System (BRSS) which has been ported from the AR/SR-47 Series to the MP5 series, featuring an electronic blowback and simulated recoil. Mach Sakai reviews this for accuracy and performance in steel series.
