Description

***UPDATE***

  • Modified geometry to make it print easier.

  • Added a variant for the up and comming HK33.


Use TPU for best performance.

Also fits HK33, HK53 and PSG-1.
I included models for all variants plus HK51 & HK21. (In case you are brave enough to build one yourself.) 

Empty Chamber Flag (EC-Flag) Features:

  • Designed to not rest against the nozzle, as to not induce stress and potential damages.

  • Pushes BB's out of HU Chamber. (No broken TV, when you demonstrate your airsoft in the living room).

  • Shows everyone on in the safe zone, that your airsoft in unloaded. (no muzzle device needed)

  • Diconnects trigger and hammer → “extra safe”

  • Made from TPU so it does not scrach your most holy possessions.

  • Now with NPAS Tool holder → 1.5mm Allen Key.

*Flag not included, but now you can print your own ;) ↓↓↓
