The Otto Arms SCAR Backplate is precision-crafted from 6AL-4V titanium, delivering superior durability compared to the factory backplate. Engineered to address common issues with buttstocks not originally designed for the SCAR, this backplate boasts an impressive shear strength of 110,000 psi—far surpassing the 30,000 psi of aluminum alternatives. Designed for compatibility with all SCAR models, it offers enhanced reliability without compromising on weight. At just 73 grams, it remains lightweight while providing a significant upgrade over the factory backplate's 49 grams.
