EGW Guns Remington 870 Scope Base Features The material choice here is worth noting: EGW Guns machines this base from extruded 7075 T6 aluminum a higher strength alloy than the 6061 used in many mounts which lets the rail stay light while resisting the flexing and thread damage that heavy 12 GA recoil inflicts on a mount over a season of slugs or buckshot. Being a single extruded piece the rail fixes the front and rear ring positions relative to one another by machining rather than by installation so ring alignment is not something the owner has to get right with two separate bases and a set of shims. The 0 MOA elevation keeps the optic s internal adjustment centered which is the correct starting point for a shotgun zeroed at slug or defensive distances where no banked elevation is needed. For the Remington 870 owner turning a bead-sighted shotgun into a scoped or red-dot gun that rigidity and neutral geometry is the foundation everything else sits on. The Heavy Duty profile sits .100 in lower than EGW s Lightweight version bringing the sight closer to the barrel centerline which shortens the sight offset and makes a red dot s point of impact track the bore more closely at the short ranges a fighting or slug shotgun actually gets used at. Full-width cross-slots gauged to MIL-STD 1913 within plus or minus .002 in mean rings and optic mounts from any maker index properly into the recoil slots and can be positioned anywhere along the rail until eye relief and head position are genuinely right. Installation uses the factory scope mount holes already present in the receiver so no drilling tapping or gunsmith is required and the socket head Torx screws and wrench are in the box; EGW recommends 20 inch lbs of torque with a drop of blue thread locker. Fitting the Remington 870 along with the 1100 and 11-87 and accepting Picatinny or Weaver rings this base is available for sale at GrabAGun.
