IMPORTANT FITMENT NOTE
This rail is designed for compatible commercial Mauser 98 Large Ring actions. Mauser-pattern rifles were produced by many manufacturers and can vary considerably. Identifying your rifle as a Large Ring Mauser does not automatically confirm that this rail will fit. We strongly recommend verifying the receiver type and measuring the mounting-hole spacing before ordering.
Product Overview
The EGW Mauser 98 Large Ring Commercial Picatinny Rail provides a modern one-piece optics mounting platform for compatible commercial rifles built around the Mauser 98 Large Ring action.
Machined from domestic 6061 T6 extruded aluminum, this rail provides a continuous Picatinny mounting surface while keeping weight to approximately 2 ounces. Full-length Picatinny cross slots give you flexibility when positioning scope rings and setting proper eye relief.
This version features 20 MOA of built-in elevation, providing additional scope adjustment for longer-range shooting. It also uses a published 3.825" center spread. Because of the large number of commercial and military Mauser variations, we recommend confirming your receiver and mounting dimensions before ordering.

Large Ring or Small Ring Mauser?
Before ordering a Mauser scope rail, it is important to determine whether your rifle uses a Large Ring or Small Ring Mauser action. The two receiver types can look very similar at first glance, especially on older commercial rifles or rifles that have been re-barreled, refinished, or otherwise modified.
Use the comparison below as a visual reference. For a more detailed explanation of receiver measurements, profiles, military versus commercial actions, and common Mauser variations, read our complete Mauser identification guide.
Small Ring vs. Large Ring Mauser Action Comparison
Not Sure Which Mauser Action You Have?
Mauser actions were manufactured in many countries and in a wide variety of configurations. Our guide explains how to identify Large Ring and Small Ring Mauser actions and discusses differences between common military and commercial receivers.

LARGE RING IDENTIFICATION DOES NOT GUARANTEE RAIL FITMENT
This product is specifically for compatible commercial Large Ring Mauser 98 actions. After identifying your rifle as a Large Ring action, you should still verify that your receiver's mounting-hole pattern matches the published 3.825" center spread.
Compatible Mauser 98 Commercial Actions
This Mauser 98 scope mount fits compatible commercial Large Ring actions including, but not limited to:
- FN Mauser Action
- Herters XK3
- Herter's Zastava J9
- Husqvarna 5000
- Interarms Mark X
- JC Higgins Model 50
- JC Higgins Model 51
- JC Higgins Model 51-L
- Parker Hale 1200
- Santa Barbara Mauser
- Zastava M70 Mauser
- Remington 798
This Mauser 98 Rail Does Not Fit
We recommend measuring the hole spacing in your receiver to confirm that it matches the dimensions published on this page.
3.825" Center Spread
This rail uses a 3.825" center spread. Because Mauser receivers can vary by manufacturer and model, the firearm's name alone should not be used to determine compatibility.
Measure your receiver before ordering. If the mounting-hole spacing does not match the dimensions published here, do not assume the rail will fit simply because the rifle uses a Large Ring Mauser-style action.
One-Piece Picatinny Rail
Picatinny cross slots run the full length of the rail, giving you flexibility when positioning scope rings and setting proper eye relief.
The center channel reduces overall mass while maintaining a continuous one-piece mounting platform. In many applications, the channel may also allow continued use of factory iron sights.
Machined From Domestic 6061 T6 Aluminum
We machine these rails in our shop from domestic 6061 T6 extruded aluminum.
After machining, the rails are tumbled, sandblasted, and Type II anodized with a matte black finish for long-lasting durability.
Why Choose 20 MOA?
This rail has 20 MOA of built-in elevation. The rail is slightly angled relative to the receiver, which allows the scope to retain more of its internal elevation adjustment for longer-range shooting.
A 20 MOA rail is particularly useful when your intended shooting distance requires more elevation adjustment than a flat 0 MOA rail would provide.
0 MOA VS. 20 MOA
0 MOA: Recommended for shooting approximately 0-500 yards.
20 MOA: Recommended for shooting approximately 500-1000 yards where additional scope elevation may be beneficial.
When zeroing a rifle equipped with a 20 MOA rail, we recommend zeroing at 200 yards.
Installation
Before installation, verify that your receiver type and mounting-hole spacing match this rail.
We recommend tightening the mounting hardware to 20 in-lbs and applying a small amount of blue threadlocker to the screws. Blue threadlocker is available separately.
#6-48 x 1/4" mounting screws and a T-10 bit are included.
Minor fitment may be required due to manufacturing tolerances and the wide variety of commercial Mauser-pattern receivers produced over the years.
VERIFY FITMENT BEFORE INSTALLATION
Do not force the rail or mounting screws onto a receiver that does not match the published dimensions. If you are unsure which Mauser action you have or whether the receiver has been modified, we recommend having the rifle inspected by a qualified gunsmith.
Made in the USA
The rail and included mounting accessories are made in the USA.
