Sig Sauer Buckmasters 3-9x 50mm Rifle Scope - Buckmasters BDC - The Buckmasters Riflescopes were inspired by Jackie Bushman to bring the performance of SIG SAUER Electro-Optics at a value that is within reach for every hunter. The riflescopes feature a custom Buckmasters Bullet Drop Compensation (BDC) reticle that has holdover dots out to 500 yards. The rangefinder will provide lightning-fast-ranging performance in a vivid red illuminated display optimized for low light hunting. As an extra value, the rangefinder can be used in "Buckmasters Mode" which comes equipped with 8 onboard ballistic groups, so the rangefinder can indicate which Buckmasters BDC holdover dot to use in your riflescope.
