A basic overview of the Sig 522 Tactical Rimfire

..................... A basic overview of the Sig 522 Tactical Rimfire, along with some additions and upgrades. In addition to the basic Sig 522 Classic, this version is the Combo version, which comes with both a 16' barrel and a 20" Match barrel. I go over basic disassembly, changing the barrel, and upgrading the Swiss style forestock for a Samson Quad Rail, and add a Magpul RVG, ARMS BUIS and other features.
