Very Good Advice,Gunsmith! A weak upfeed out of a magazine is a definite Deal Breaker. While we're at it it,while it may be true that a Law passed in a time of UnConstitutional Liberal Law Making Fervor is not Legal,it still takes money to fight it in Court. They're counting on you to be angry,but not Financially Supportive of that Court Fight. Back Your Anger and Dismay with a Contribution to the Legal and Legislative Branch of the National Rifle Association,the NRA/NLA. To me,they are the still the best Centralized Fighting System available to Fight for the Second Amendment,and Citizen's Firearm Rights that we have available to us. They are Hated,and that's a good thing. Being Hated means you are garnering good results against your Opposition.
