Wanted: Mag extensions for 10/22

Looking for anyone who is printing mag extensions for the factory Ruger BX1 10 round rotary mags. I would like them to simulate the look of the M4 pmag 30’s,I’d settle for 20’s if that’s all that’s available 

Any help would be appreciated 

Pic is the look  I’m going for,should also mention I am not looking to add ammo capacity,only looking for the ecstatics  

Thanks
