Hi all, I'm gettin ready to start a saum build on the defiance ultralight in a medium "SA" or their xm action. I have been told that these have had feeding problems unless you run a detachable mag. I don't really want to run a detachable mag if I don't have to, does anyone have any experience with this or is it a myth? Any one built one on the defiance action which action would be best SA or XM?
Thanks
