Sometimes a deal thats too good to be true…is.
Case in point, the Mossberg 590A1 I picked up. Took it to the range today. Loaded it up, brought it up to my shoulder, pumped the action and…..a shell popped out of the mag tube, missed the carrier, and landed at my feet. Hmmm.
Apparently, every time I worked the action, the shell lifeter would go down but no shell would be released into it by the magazine. You don’t have to be a genius to figure it’s something with the shell stop tab or shell interrupter.
First things is first…hit YouTube and get a disassembly video. Pulled the gun apart, cleaned everything, light oil, and back together.
Same problem.
Now here’s where it gets interesting. One of the cool things about having redundant backups is that rather than guess what part was giving me trouble, I could simply swap parts from a gun that I knew was functioning perfectly, put them in the trouble gun, and see if that made a difference. I pulled a Mossberg 500 outta storage, disassembled it, pulled out the stop and interrupter, exchanged them, and….joy. But because I had a similar model to swap parts from, I was able to swap parts to find what was the problem part. The alternative was to guess, replace several parts, or hand the thing over to a gunsmith.
A quick trip to Mossberg’s website got me several replacement parts for $30. That puts my basis on the 590A1 to about $165. Still ahead of the game. And, as a plus, I learned how to completely take the bloody thing apart. And I picked up some spare parts.
I’ll take the 590A1 to the range again later this week to confirm function, and when the replacement parts get here I’ll put them in the ‘donor’ 500, function test it, and put it away.
Moral of the story? A handful of 12 ga. dummy snap caps would have tuned me into the situation ALOT earlier.
