Tuf-22 mags 25 round ruger 10/22

These magazines have a block on them so they will not fit in unmodified 10/22 receivers. That is why they remain legal at 25 rounds when BX-25s have to be pinned. You need a TUF-22 or 11/22 receiver, or to dremel a small slot in your stock 10/22 (this is pretty easy and does not prevent you from using normal magazines) to use them.

I can ship if you cover it, pal required I have a couple kicking around if you need more than one
