So, this is just a sad sob story. It is me being sad and sobbing!
In 1999, before the big bad bans took place in the Peoples Republik of Kalifornia, I bought a total of 16 "M14 Magazines". These are 20 round mags, I got them, I put them away, I never touched them.
I had one 10 Round Mag, and one 20 Round mag, and these are all I ever used when I took the rifle to the range.
I finally decided to take these mags out to the range. I first tested each one with 5 dummies on the bench and made adjustments as needed. 13 of the 16 functioned with 10 rounds at the range. BUT, when loaded with 15 or more rounds, they all failed. Mostly, they spit rounds (unfired) out during each cycle. They also tended to swell to the point where it was difficult to seat the mag into the rifle.
I took some apart after returning from the range, and the bottom retaining plates could be bend into a banana shape and not return to normal, indicating that these are not tempered or heat-treated.
End result, these mags as they are can not be trusted or relied upon.
My question is this: Can I reasonably heat treat the mag bodies, or should I just resign myself to buying replacement parts. Since I live in Kalifornia, this would be my ONLY recourse under the law.
I welcome your thoughts and input.
BTW: Does anyone out there have any mag bodies that they might be willing to part with? Springs I can get. Followers I can get, Floorplates I can get. Bodies is what I need.
