This is a discussion on 17S magazine for 20s? within the Want to Buy forums, part of the FN Forum Marketplace category; I'm looking to buy a new mag for my 20S. Cant seem to find one anywhere!
will this work?
Mags for 17 and 20 are the same as jaflowers said. The mag that comes with the rifle is a 10 rounder. I like the 10 round better because I like the rifle lower when I firing it prone but the 20 works fine.
