I was very sceptical about electric air rifles, and couldn't understand the attraction that daystate held for some of my fellow shooters.
Then I got a Mk4 in a sporter stock and I was in love. For me, it is the best sporting rifle bar none. I have had HW100's, S400, and a range of other target rifles, but IMO as a sporter and for some target shooting it is best in class.
No problems with the electric, just a new battery after 3 years.
