Two new videos from RA-Tech for the mid-week. The first is the custom slide sets for the KJ Works gas blowback pistols which are mainly the KP-07 or the KJW 1911 and the KP-08 or the KJW Hi-Capa pistols.  All these slides come with their markings and the video shows them put in test. The other test is about the RA-Tech NPAS Nozzle which is installed in the WE SCAR-L Gas Blowback Rifle.
