Originally designed and patented by Beta Mag Inc.
These are out of a batch of 50 that I bought many years ago, half of them are now being sold to fund another important project. The ones I have tried out of this same batch have worked 100%.
These have the smoke colored transparent bodies that are easy to clean and load, they are also equipped with the roller/coil springs that never wear out. You can keep them loaded without fear of spring set. They come in my now famous 4mil thick Zip Locks bags suitable for long term moisture proof storage.
