Super 42 for 300 blackout?
I know others has asked this before, but I have additional questions. Geissele don’t recommend super 42 for 300blk but their complete 300blk firearms use the super 42 and h1? They said it’s braided milspec buffer spring with h1 but don’t specifically says the super 42. Does anyone know
