Sig Sauer Alpha MSR Features The Sig Sauer Alpha MSR is machined from proprietary aluminum with an exactness that delivers both strength and ductility allowing the integrated steel rings to form securely around a riflescope without damaging the tube under proper torque and installation. The epoxy powder-coated steel rings resist oxidation gun oils cleaning solutions and outdoor exposure for long-term durability and reliable zero retention through sustained field and range use. At 7.33 in length and a 1.535 mount height the Alpha MSR positions a 30mm scope at the optimal height for MSR platforms with flat-top Picatinny receivers. The Alpha MSR 30mm one-piece scope mount is constructed from black anodized aluminum for a lightweight corrosion-resistant profile that keeps total system weight to just 7 oz without sacrificing the rigidity and zero retention that precision MSR shooters demand. All necessary mounting hardware is included for immediate installation on any standard Picatinny rail without additional purchases. The Alpha MSR is designed to complement the Sig Sauer Tango-MSR scope lineup providing a purpose-matched mounting solution for a complete factory-integrated MSR optic package.
