I designed an MP7 Foregrip that mounts to picatinny rails.
I started by designing an adapter for my MP7 foregrip that I had taken off my VFC/Elite Force MP7 AEG. I then realized how simple the design of the grip itself was and decided to draw that up as well.
You pill need:
a 4mm roll pin or set screws
a 7.9mm pin or a 1" 8-32 screw w/ the included pin
a spring with a max OD of Ø12.5mm and >44mm long
The spring goes between parts 02 & 03 of the grip.
Update 03/04/2022:
Added MP7_Foregrip_AdapterV2, now with 2 screw holes for more secure mounting to pic rails
Update 10/03/2022:
Added MP7_Foregrip_AdapterV3, it is shorter and should grab the picatinny rails better.
Updated the V2 version for better picatinny grip.
Added a V2 STEP with updated components.
