APFG MCX Bolt Carrier Group Takedown + NPAS Install | YNS Tactical Technical Guides

We take a look at the takedown and reassembly procedure of the APFG MCX's bolt carrier group. Once again this is applicable to all three models available, with some very minor differences for the MCX legacy which should not need any special attention or change of the procedure shown. We will also cover how to install an NPAS valve in the nozzle to adjust your FPS for varying field limits, as well as some information on lubricating this entire assembly, and finally a bit of insight on how to take care of a stripped screw. 0:00 - Introduction 5:54 - Recoil spring and guide rod disassembly 7:23 - Nozzle removal: Nozzle stop 9:28 - Nozzle removal: Heat gun extraction of return spring screw 13:44 - Nozzle disassembly 16:20 - Comparison of fixed valve vs NPAS valve 17:24 - NPAS install and Nozzle Reassembly 20:50 - Lubricants and threadlock used for this job 23:07 - Reinstalling the nozzle into the bolt carrier 26:08 - Recoil spring and guide rod reassembly
