Guaranteed Perfect Fit and Ease of Installation Unlike the competitors “universal fit” rails, the G2SA Arca Rail has been meticulously engineered to precisely fit the 2nd Generation Ruger American short action rifle stocks (will also fit most late-model, post 2017, Gen 1 stocks). Our design goals for the G2SA were to produce a high quality, lightweight but rigid, full-length Swiss-Arca adapter system that is precisely contoured to match the Ruger stocks and could be quickly and easily installed by anyone. In addition to the precision fit and ease of installation, the G2SA is very attractive and looks like it belongs on the rifle. Unlike other rails, the G2SA doesn’t look or feel bulky, and all edges have been rounded or chamfered to ensure comfortable off-hand shooting that feels natural. Machined from aircraft-grade 6061-T6 aluminum and finished in a tough, attractive H-190 Cerakote, the 10.25" rail offers a full-length Swiss Arca mounting interface—ideal for securely attaching tripods, bipods, and other accessories. Beyond its modularity, the G2SA rail addresses the Ruger’s biggest weaknesses by greatly improving the stock’s fore end stiffness, providing a more solid and stable shooting platform to fully realize the Ruger American’s full potential! Installation is quick and easy, thanks to the included drill guides, quality hardware, and clear instructions. Most users can complete installation in under five minutes with no specialized tools or gunsmithing skills required.
