Gun stock U.K.

Hi I’m hoping someone can help me. My son is asking for an Enforcer Revolt - Haptic Rifle Stock with Force Feedback for Quest VR from deadeyevr which isn’t in stock. We are in the UK. I’d like to get one for his 13th birthday that’s really good. He currently has a 3d printed one he doesn’t like (Sanlaki Pullstock ELITE Gunstock and a magnetic one from Amazon).

Any recommendations on something that’s in stock I can order?

Thank you in advance 🙏🏻
