Description
If you have been running your Marlin 1895, 336, or 444 on iron sights and want to add glass, this EGW rail is one of the cleanest ways to do it. It is a one-piece Picatinny base machined from domestic 6061 T6 extruded aluminum and finished in matte black anodizing, so it holds up to the recoil of the big bore lever guns without flexing or beating itself loose. The cross slots run the full length of the rail, which means you can slide your rings fore and aft to get the right eye relief no matter what scope or red dot you are mounting.
What the EGW 47100 Rail Fits
This base covers a wide spread of lever guns and pistol-caliber carbines. Beyond the Marlin 1895, 336, and 444, it also fits the Model 36, Glenfield 30, the Henry 3030 (H009) and 4570 (H010), plus the Camp Carbine 9mm and Camp Carbine .45 ACP. It is pre-drilled to match the factory tapped holes with a 2.75 inch center spread, so for most folks it is a straight bolt-on job with the included hardware.
Low Profile and Iron Sight Friendly
The rail sits right around 0.4 inches high and keeps weight down thanks to a relieved channel through the center, coming in at roughly 2 to 3 ounces. That center channel does double duty: it trims mass and, in many setups, leaves your factory iron sights usable underneath the rail. Pair it with see-through or quick-detach rings and you can keep your backup irons in play.
Built to Hold Zero
EGW machines these in-house on their own equipment, and that attention shows up in the fit. Owners of .45-70 Guide Guns and Henry 45-70s consistently report the rail dropping onto the pre-tapped holes and lining up with no fuss, holding zero even under heavy-recoiling loads. A dab of thread locker on the screws and you are set for a lifetime of hunts.

Frequently Asked Questions
Will this EGW rail fit my Marlin 1895 and 444?
Yes. The 47100 is designed to fit the Marlin 1895, 336, and 444, along with the Model 36, Glenfield 30, and several Henry lever guns. It uses the factory tapped holes on the receiver with a 2.75 inch center spread, so for most rifles it is a direct bolt-on install.
Can I still use my iron sights with this rail mounted?
In many cases, yes. The relieved center channel in the rail is designed to clear the factory irons, so pairing it with see-through or quick-detach rings lets you keep your backup sights in play. Fitment can vary by sight setup, so it is worth checking your particular rifle.
What rings do I need for the EGW 47100?
This is a Picatinny-style base, so it accepts both Picatinny and Weaver scope rings. Choose your ring height based on your scope's objective size and whether you want to see through to your irons underneath.
Is this rail strong enough for heavy recoiling calibers like 45-70?
It is. The rail is machined from 6061 T6 aluminum and anodized matte black, and owners running hard-kicking 45-70 loads report it holding zero without issue. A little thread locker on the screws is smart insurance against the recoil backing them out.
