Sam - I dont know. I have only ever used them on a Empire Mini, Axe and Vanquish. Whilst owning these i have never used on other guns so cant comment.
From what I have heard the Luxe is similar-ish to a Vanquish so if this is the case I would think all ok.
If you are playing at either a Formula 5 Event or a Southern masters then you would be more than welcome to try one out.
Let me know.
