Description

Description:
Put this adapter between your blaster and stock so that you can add 60mm spaced fidlocks for your holser.

Materials:
2x M5 Fidlock Bolts
2x M4 Nut
2x M4x30mm Socket Cap Head Screws
2x M4x10mm Socket Cap Head Screws
3x M3x14mm Socket Cap Head Screws

Printing Instructions:
Use supports necessary. I recommend PETG with 5 walls and 25% gyroid infill, but PLA should be fine.

Installation Instructions:
1. Insert 2 M4 nuts in slots on the picatinny part.
2. Slide the female picatinny over the blaster picatinny. The 3 holes should be on whichever side you want to have the fidlocks.
3. Secure the picatinny adapter to the blaster with 2 M3x30mm screws. They should tighten against the 2 nuts.
4. Add the 2 M4x10mm screws to the center section of the other part (with the cat!). These are there to reinforce the adapter.
5. Add the fidlock bolts to the raised circle areas on the adapter. They should be as snug as possible.
6. Set the fidlock portion on the picatinny area in your chosen orientation. The Slot on the fidlock adapter should fit into the groove on the picatinny part.
7. Tighten 3 M3x14mm screws to connect the parts.
