so this is probably a very stupid question but here it is. i just bought my gf a mark II FV 22lr that is the heavy barrel, it came with 5 round mag. my question is can i put my mark II F 22lr 10 round mag in there? i figure i can but why wouldnt they just sell them with 10 round mags to begin with?

second question does anyone make a high capacity mag for the mark II, if so where.

thank you
