NoBeginner Posted August 17, 2007 Share Posted August 17, 2007 Who knows how long it has been since I ran 21 quick rounds through my M-3. Certainly not since I last gave it a major cleaning and lube. Imagine my surprise when the shotty would no longer cycle. When I shook the gun it sounded like loose shells in the magazine extension. HMMMMMMMMMMMMMMMMMMMMMMMMMMMM. Nothing I could do at the gun range without my tools...so back home I went. Tried multiple different approaches before giving in to the idea that a full strip might be in order. Lo and behold, when I was carefully loosening the barrel/magazine extension bracket....I heard the magazine follower fly back toward the bolt. Most likely explanation, I had overtightened the barrel/magazine extension bracket. Solution, less torque and some blue (NEVER RED) locktite. Since I had all of my supplies out anyway, I figured why not do a full strip and lube.....but this time be sure to give the magazine extension extra attention. Long story short, there was also a lot of rust and debris inside the mag extension and it took gun blaster to get it all out. Moral: don't expect your self-help/home defense shotgun to work when you need it most if you don't regularly run full bore shoot-as-fast-as-you-can exercises. Without trying to hard, I can guess how deep the do do would have been if I had only gotten one round out and then the gun jammed and would not fire at all.

HDRDKG Posted August 17, 2007 Share Posted August 17, 2007 How would you get rust in the mag tube? Did the spring rust? Quote Link to comment Share on other sites More sharing options...
tucker301 Posted August 17, 2007 Share Posted August 17, 2007 Good advice! If it won't cycle, it may as well be a Louisville Slugger. Quote Link to comment Share on other sites More sharing options...
NoBeginner Posted August 17, 2007 Author Share Posted August 17, 2007 Because I did not dissassamble the entire magazine extension, I cannot tell you for sure if the rust was limited to the spring or not. How did the magazine extension get rusty? Well the shotgun has been in a gun safe with a golden rod de-humidifer for more than 20 years. Other parts of the shotgun had so little rust, that I only noticed minor amounts when I put another coat of gun oil on it. Quote Link to comment Share on other sites More sharing options...
HDRDKG Posted August 17, 2007 Share Posted August 17, 2007 Well the mag tube is aluminum, so it must have been the spring. I always take a shotgun patch, put oil on it and then turn it through the entire spring. Never had one rust. Quote Link to comment Share on other sites More sharing options...
