Budget VR Gun Stock for PICO 4

This is the budget VR gun stock for PICO 4: the protubeVR starter frame with cradles shaped for the PICO 4 controllers. Both controllers lock onto one frame for a steady two-hand hold, from €100 for the bare frame.

A PICO 4 gun stock that does not cost a lot

PICO 4 accessories are thinner on the ground than Quest ones. This is a low-cost, modular option that fixes the two PICO 4 controllers to one frame.

PICO 4 controller cradles

Shaped for the PICO 4 controller ring; twist-release for reloads.

Tracking clearance

PICO 4 tracks its controllers from the headset — the bottom-mounted cradles keep that view clear.

Shoulder stock & armature

• No stock — bare frame, lowest price.
• MK1 Static — fixed shoulder stock.
• MK2 Adjustable — adjustable-length shoulder stock.
• Haptic Explorer — adds a ForceTube-style haptic stock.

Armature in chrome or black carbon-fibre; parts in grey, black carbon, red or white.

FAQ

Does it fit the PICO 4 Ultra? No — the Ultra has different controllers. See the PICO 4 Ultra version.

Does it block PICO 4 tracking? No — the cradles are bottom-mounted.

Is €100 the whole price? That is the bare frame; a shoulder stock or the Haptic Explorer option costs more.
