These Sten mags were purchased as a lot from a 07/SOT who used them for his firing range rentals. They’ve all been disassembled and cleaned in house, removing dirt, grease, and most corrosion. After cleaning each magazine was tested with 5 dummy rounds of 9mm, 2 times in a 3D Printed SVTR lower, to ensure they fed reliably. While pictured, the Sten mags with Bubba’s patent pending speed loader (which is actually pretty rad) have all been sold. If you have a color preference (blued vs steel) please indicate in order notes and I’ll do my best to accommodate.
