After reading all the reviews about the blitz my desire to own one finally exceeded my trepidation and I pulled the trigger (pun intended) I ordered the 30 cal and when it arrived I made sure to clean and lube it very carefully as well as working the charge handle in with about a thousand full action travel manual engagements as is my personal preference on way to make smooth like butter. Bottom line is mine does not jam for whatever reason and that makes me extremely happy because without the jamming issues this is an amazing rifle. I can’t believe how fast it runs a mag through. Like three seconds! Home defense? Idk who can walk through absorbing 30 30 cal rounds in 3 seconds at 700fps but if they can, a twelve gauge ain’t stopping them either.
