The Ruger No. 1 is a beautiful rifle, but its factory scope setup can feel limiting when you want to run a modern optic. This EGW HD Picatinny rail solves that by giving you a full-length one-piece base with true MIL-STD 1913 cross-slots, so you can slide rings fore and aft to dial in exactly the eye relief you want. It drops onto the factory scope mount holes on the receiver, which means no drilling and no tapping to get it on the gun.
This is the Heavy Duty version, machined from ultra-rigid extruded 7075 T6 aircraft-grade aluminum and finished in a durable matte black Type III hardcoat anodize that holds up in the field. The HD design sits about .100 inch lower than the lightweight bases, which keeps your optic tucked closer to the bore centerline for a cleaner cheek weld and better repeatable accuracy. The full-width cross-slots are gauged to MIL-STD 1913 specs within plus or minus .002 inch, so your rings and any Picatinny or Weaver accessory seat where they should.
This rail is built for the Ruger No. 1 B and 1 S barrel contours and mounts flush on the stock recoil pins in the barrel. It is not made for the Ruger No. 3. Because Ruger has placed recoil pins in slightly different spots across calibers, it is worth measuring your hole spacing before install, but the mount is designed to use the mounting screws as the primary recoil lugs so it functions properly regardless. EGW recommends torquing the hardware to 20 inch-pounds with a drop of blue Loctite on each screw.
From the screws and wrench right down to the packaging, the whole thing is made in the USA. If you have been wanting to top your No. 1 with a bigger scope or a longer-range setup, this is the clean, no-fuss way to do it.
It is designed for the Ruger No. 1 B and 1 S barrel contours and mounts flush on the barrel's stock recoil pins. It is not compatible with the Ruger No. 3. Because Ruger locates recoil pins differently across calibers, it is smart to measure your hole spacing first, though the mount still functions using the mounting screws as the primary recoil lugs.
No. The rail is made to drop onto the factory scope mount holes already on the receiver, so there is no drilling or tapping required. EGW recommends 20 inch-pounds of torque on the hardware with a drop of blue Loctite on each screw for a lasting hold.
A 0 MOA rail sits flat with no built-in cant, which is ideal for hunting and general shooting inside roughly 500 yards. A 20 MOA rail adds downward angle to give your scope more internal elevation for longer ranges. For a classic No. 1 used at typical hunting distances, 0 MOA is the way to go.
The cross-slots are cut to MIL-STD 1913 specs, so any standard Picatinny or Weaver rings will seat properly. That gives you a wide range of ring height and diameter options to match whatever optic you choose. The full-length slots also let you shift rings forward or back to fine-tune eye relief.
