I found this post from 2006 with sniper22 stating around 20 MK2s were made. http://www.airgunbbs.com/showthread....991-mirage-xlr
The post also states that 230 were made.
The MK2 mentioned is 2188 and I have found a picture of a MK2 with serial no. 2219, which if numbers were consecutive, suggests more than 20 were made.
