450 Magazine Options
Posted: Thu May 19, 2011 11:47 amI just got word from Cabela's that my .450 Bushmaster upper is headed my way.
What are the magazine options? Do the 30rd Sig 556 mags work without modifications, and how many rounds do they hold?
Do the 20rd mags also work, and how many rounds do they hold?
Thanks!
Dean
