Iâm aiming to get a GSG-16 as my first submachine gun (I refuse to call it a rifle, since the standardized naming system is so shit). Theyâve got good enough reviews, and so do the 110-round drum magazines you can get. Altogether Iâm looking at about $600 for the gun plus the large mag plus a cheap holographic sight. And thatâs great, because I live in Canada. This place is quickly devolving.
