Lancer Tactical Alpha Stock Fixed HPA QD Baseplate

thingiverse

I built an airsoft Polarstar M4, but I didn't like how the HPA line was all floppy inside the grip. I couldn't use an existing baseplate to fix this issue, as the Lancer Tactical Alpha Stock uses a nonstandard setup with one pin and a screw instead of two screws. This adapter serves as a sturdy place to mount the HPA line's QD connector. To install, simply feed the HPA line through the hole in the bottom of the baseplate, pull it through with some needle nose pliers, insert the hose into the QD fitting, push the QD fitting into the hexagonal hole in the baseplate, and use the original mounting hardware or a small screw and metal pin to secure the baseplate onto the bottom of the gun. This particular gun uses a Polarstar Kythera that has been modified to connect the charging cable to the charging handle. If you want to use a mechanical HPA engine as well, you will need to do something similar, as there is no room to feed the charging cable through the bottom of the grip. Print in PETG or ABS for durability and thermal stability.
