I've got a 516 striker in 308 that I have converted to 300blackout. It has a blind box mag. I know there aren't many strikers around period but they share a lot of parts with the rifles. The last hang up is the mag. Numrich list the part but I'm not sure if you can just swap the blind mag. Any wisdom?
Theres probably 1000 blind mags in parts bins from folks that have upgraded. Any places you recommend asking ?
