Description
Topping a classic Marlin lever gun with a modern optic used to mean fighting with flimsy two-piece Weaver bases. This EGW rail fixes that. It's a single piece of 6061 T6 extruded aluminum machined to the Picatinny standard, finished in a matte silver Type II anodize that pairs nicely with stainless or lighter-finished receivers. At roughly 2 ounces and just over 5 inches long, it adds a real mounting surface without turning your handy lever gun into something bulky.
Fitment Across the Marlin Lineup and Beyond
This rail uses the Weaver 63B receiver pattern with a 2.75 inch center spread, which covers a wide range of rifles. It fits the Marlin 1895, 336, 375, 444, Model 36, and the Glenfield 30, and it works on the newer Ruger-made Marlins since Ruger kept the same receiver hole spacing. Beyond Marlin, it mounts to several Henry lever actions including the 30-30 (H009), 45-70 (H010), and the .410 (H018, 20 inch barrel only), plus the Rossi 95 and later Camp Carbine 9mm and .45 models. Since there are a few different hole patterns floating around out there, it's smart to measure your receiver spacing against the 2.75 inch spec before mounting.
Mounting the Silver EGW Rail
Installation is a straightforward drop-in job using the factory drilled and tapped holes on your receiver. The rail comes with #8-40 x 1/4 inch screws and a T-10 Torx bit, and EGW recommends a drop of blue threadlocker with the screws torqued to 20 inch-pounds. Full-length Picatinny cross slots let you slide your rings fore and aft to dial in eye relief, which matters on scout-style and LPVO setups where head position is everything. The center channel trims weight and in many cases leaves your factory iron sights usable as a backup.
What the EGW Rail Works Best With
The 0 MOA cant is the right call for the typical ranges these rifles see, generally inside 500 yards. Keep in mind this rail is not quick-disconnect compatible, so it's built to go on and stay put. It accepts both Picatinny and Weaver-style rings, giving you plenty of room to run anything from a compact LPVO to a traditional hunting scope.

Frequently Asked Questions
Will this EGW rail fit the new Ruger-made Marlin rifles?
Yes. Ruger kept the same receiver hole spacing as the original Marlin models, so this rail is compatible with the new production 1895, 336 and other covered models. It still uses the factory drilled and tapped holes, so no gunsmithing is needed.
Does the Marlin Picatinny rail come with mounting hardware?
It does. The rail ships with #8-40 x 1/4 inch screws and a T-10 Torx bit. EGW recommends a drop of blue threadlocker and torquing the screws to 20 inch-pounds for a solid, lasting hold.
Can I still use my factory iron sights with this rail installed?
In many cases, yes. The center channel is cut out to reduce weight and often leaves a clear sight line to the factory irons as a backup. It's a good idea to check clearance with your specific sight setup once the rail is mounted.
What scope rings work with this EGW silver rail?
The top is cut to the Picatinny standard, so it accepts both Picatinny and Weaver-style rings. The full-length cross slots let you position your rings forward or back to nail down proper eye relief, which is handy for LPVOs and scout-style scopes.
