EGW Guns Heavy Duty Scope Base Features The EGW Guns Heavy Duty Scope Base is machined from ultra-rigid extruded 7075-T6 aluminum a stronger alloy than EGW s standard lightweight bases and suited to the recoil of magnum Weatherby cartridges. Its Heavy Duty design sits .100 inches lower than the Lightweight version keeping the optic closer to the bore centerline for improved accuracy and a lower overall profile. Full width cross slots are gauged to MIL-STD 1913 specs within plus or minus .002 inches ensuring Picatinny or Weaver rings seat securely and can be adjusted for proper eye relief. The built-in 20 MOA of elevation shifts the scope s adjustment range toward distant targets giving long-range shooters more usable travel before running out of turret. At just 2.5 ounces and a 7.064 inch overall length the base adds negligible weight to the rifle while covering the Mark V s 9-lug bolt action receiver with a 4.485 inch center spread. EGW includes number 6-48 by 1/4 inch screws and a T-10 wrench and recommends 20 inch pounds of torque with a drip of blue Loctite for a secure long-term mount. The base is also compatible with quick disconnect rings giving shooters the option to remove an optic without losing zero. For a Weatherby Mark V owner chasing distance this EGW Guns Heavy Duty Scope Base delivers the elevation and rigidity a long-range build demands.
