***Doesn't fit the TM22-S-18 shown below.

These magazines will not fit the TM22-S-18 without modification. The TM22-S-18 uses a magazine tube with a notch on the back that locks the magazine into the magwell.

Your rifle may be marked TM22-A-18 even if it is actually a TM22-S-18. These rifles share some parts, so the markings on the rifle can be misleading.

If your rifle looks like the one shown below and the magazine locks into the magwell using a notch on the rear of the magazine tube, these magazines will not fit as-is. The magazine would need modification: cut a corresponding notch in the rear so it can lock properly into place.

If your rifle matches the picture below, do not purchase these magazines unless you are prepared to modify them.***
