I cant see them on the daystate website yet for sale, but personally I have never had an issue with the Mag that came with my airwolf or the one with my red wolf. plus 3 others I have purchased. I do shoot 1.77 if that makes any difference.
I've owned 4 calibers of Daystate rifles from .177 cal. to .30 cal. and on each rifle the pellet probe developed nicks that gradually increase with use. From reading about other Daystate owners I came to the conclusion that the magazine actuator design causes this problem by striking the pellet probe.
I also had a sudden problem with loss of accuracy with my .22 caliber Daystate Wolverine Hi lite. Apparently, the damaged pellet probe gradually ate-away at the breech O-ring. When I described this loss of accuracy to the technician over the phone, he immediately diagnosed the problem -- "probably an O ring" -- without telling me about this common problem with these rifles.Then, he charged me for shipping the rifle to them for repair, as if the problem with a practically new rifle was my fault.
As with "Hawkeye69" above, I will not purchase another Daystate rifle. Nor will I patronize the vendor who sold me the rifle.
