I'm new to firearms in general so I'm still learning but recently my G-Force GFY1 12 Gauges' magazine release button just disappeared looked all over and I cannot find it. My issue is I cannot find a replacement for it either I'm using the wrong terminology or in looking for the wrong type or something. Can anyone show me where to purchase the parts or a lease what I should be looking up?
