Handy TEC9 Stock Buttstock TEC-9

Newly purchased Handy TEC9 from PDD, found that the tail has M4 screw holes, convenient for installing the buttstock, so I designed the corresponding buttstock. If your version does not have screw holes, the connecting part needs to use glue, please note.

Two versions are designed:

1) Version 1: Suitable for the original TEC9, use the M4 screw at the tail of the TEC9 to secure the connecting part, then fix the buttstock part to the connecting part with two sets of M4*25mm locking screws;

(If your version does not have screw holes, glue is needed when fixing the connecting part to the main body)

2) Version 2: Matched with Deep Blue’s upper receiver designed by the boss, the Picatinny rail part is redesigned and extended. Based on version 1, the Picatinny rail and the connecting part can be fixed with screws, further increasing the strength; Use the M4 screw at the tail of the TEC9 to secure the connecting part, then fix the buttstock part to the connecting part with two sets of M4*25mm locking screws;
