Description
The Remington 597 is a great little semi-auto rimfire, but getting glass mounted solidly on it isn't always the smoothest job with factory options. This EGW rail fixes that by giving you a full-length, one-piece Picatinny surface across the top of the receiver, so you can run modern scope rings, a red dot, or just about any other Pic-compatible accessory with no guesswork.
It's machined from domestic 6061 T6 extruded aluminum and wears a matte black anodized finish, so it holds up to real use and matches the gun nicely. At 6.276 inches long and about 2 ounces, it stays light, thanks in part to the milled channel running down the center that trims weight without giving up rigidity. The cross-slots run the full length of the rail, which means plenty of room to slide your rings fore and aft and dial in exactly the eye relief you want. It's also ambidextrous, so lefties and righties are both covered.
Why the 0 MOA Setup Makes Sense on a 597
For a rimfire like the 597, the 0 MOA rail is the way to go for typical plinking and small-game distances. A flat 0 MOA base keeps your scope's adjustment range centered, which is ideal when you're working inside about 150 yards where most .22 LR shooting happens. If you were stretching things way out, a 20 MOA base makes more sense, but for this platform the 0 MOA keeps your zero simple and your turrets in a comfortable range.
Installing the EGW 597 Rail
The rail is drilled to match the factory scope mount holes on the 597 receiver, so it lines up clean with no drilling or tapping on your end. EGW includes the #6-48 screws and a T-10 bit in the box, and recommends torquing to 20 in-lbs with a drop of blue Loctite to keep everything locked in. Builders consistently report all the holes lining up right and the rail sitting tight with zero movement once it's properly torqued. In many cases it also sits low enough that it won't block your factory iron sights.

Frequently Asked Questions
Will this EGW rail fit my Remington 597?
Yes, this 40300 rail is made specifically for the Remington 597 rimfire platform. It's drilled to line up with the factory scope mount holes on the 597 receiver, so it bolts right on with no drilling or tapping. Users consistently note all the screw holes lining up cleanly.
What's the difference between the 0 MOA and 20 MOA version?
The 0 MOA rail sits flat and keeps your scope's adjustments centered, which is ideal for the shorter distances a .22 LR 597 is typically used at, roughly out to 150 yards. The 20 MOA version adds built-in forward cant to squeeze out more elevation for longer shots. For most 597 plinking and small-game work, 0 MOA is the practical pick.
What rings work with the EGW 597 Picatinny rail?
It accepts standard Picatinny or Weaver-style scope rings. The cross-slots run the full length of the rail, so you have plenty of positions to mount your rings and fine-tune eye relief. It is not compatible with quick-disconnect ring systems.
Does installing this rail block the factory iron sights?
In many cases the rail sits low enough that it won't obstruct use of the factory iron sights, though this can vary with your exact setup. EGW recommends torquing the screws to 20 in-lbs with a drop of blue Loctite to keep everything locked in place.
