If you want them cut to the same length as the standard 13 inches, please give us a note in the comments section of your order. Will also fit Sten 9mm, SMG and semi auto Mac type magazines.

These are factory used Sten magazine springs for the 32 round mags. These have been sitting in boxes for many years but still have plenty of life left in them. Some are greasy and oily and do show age but are a good replacement for a damaged or lost mag spring. Can also be used for a replacement in a zytel or M-11 32 round magazine.
