The Ruger American is a budget-friendly rifle that offers a lot of performance. If you want to maximize accuracy and increase modularity, a chassis is a good upgrade, and MDT makes several chassis that complement the short action Ruger American. Do you own a Ruger American that feeds from an AR-15 magazine-compatible caliber? We make an MDT LSS XL Gen 2 that accommodates a STANAG/AR-15 magazine. If you want to build a training rifle or platform for a younger shooter, the MDT LSS complements the Ruger American 22 LR rimfire rifle.
