Product Overview

Is Your Mauser a Large Ring or Small Ring?
Before selecting a Mauser scope mount, it is important to determine whether your rifle uses a Large Ring or Small Ring receiver.
As a general reference, Small Ring Mauser receivers typically measure approximately 1.300" across the front receiver ring, while Large Ring Mausers typically measure approximately 1.410". The Large Ring action usually has a more pronounced step where the enlarged front receiver ring meets the narrower portion of the receiver.
Small Ring vs. Large Ring Mauser Receiver Comparison
Not Sure Which Mauser Action You Have?
Mauser actions were produced in many countries and configurations, and model names alone do not always tell the complete story. Our Mauser identification guide explains how to distinguish Large Ring and Small Ring actions using receiver profile, measurements, and common model examples.

IDENTIFICATION IS ONLY THE FIRST STEP
Confirming that your rifle has a Large Ring receiver does not by itself confirm rail compatibility. This product is for compatible commercial Large Ring Mauser 98 actions. Always verify the mounting hole pattern and the published 3.825" center spread before ordering.

This Rail Does Not Fit
Mauser-pattern receivers vary considerably. We recommend measuring the mounting hole spacing in your receiver and confirming that it matches the dimensions published on this page.
3.825" Center Hole Spread
This rail uses a published 3.825" center spread. Receiver identification and model name should be used together with actual mounting-hole measurements when determining compatibility.
If your receiver's mounting pattern does not match the published dimensions, do not assume the rail will fit simply because the rifle is described as a Mauser 98 or Large Ring action.
One-Piece Picatinny Mounting Platform
Picatinny cross slots run along the rail, giving you flexibility when positioning scope rings and setting proper eye relief.
The center channel reduces unnecessary mass while maintaining a continuous one-piece mounting platform across the receiver.
A one-piece rail also gives you more freedom to position rings than traditional front and rear two-piece bases.
6061-T6 Aluminum Construction
We machine this rail from domestic 6061-T6 extruded aluminum in our shop.
After machining, the rail is tumbled, sandblasted, and finished with matte black Type II anodizing for a durable, low-glare finish.
0 MOA Configuration
This version uses a 0 MOA mounting surface with no additional elevation built into the rail.
For customers who need additional built-in elevation, we also offer a 20 MOA version of this commercial Large Ring Mauser 98 rail.
Installation
Before installation, verify that the receiver configuration and mounting-hole spacing match this rail.
Clean the receiver mounting surface and hardware before installing the rail.
We recommend tightening the mounting screws to 20 in-lbs and applying a small amount of blue threadlocker to the screws. Threadlocker is sold separately.
The rail includes #6-48 x 1/4" mounting screws.
Minor fitment may be required due to manufacturing tolerances and the wide variety of Mauser-pattern receivers produced over the years.
VERIFY FITMENT BEFORE INSTALLATION
Do not force the rail or mounting screws into a receiver that does not match the published dimensions. Mauser actions can vary substantially by manufacturer, model, and previous modification. If you are unsure of your receiver configuration or mounting pattern, have the rifle inspected by a qualified gunsmith.
Frequently Asked Questions

How can I tell if I have a Large Ring Mauser?
Large Ring Mausers typically have a visibly enlarged front receiver ring and measure approximately 1.410" across the front ring. Small Ring receivers are typically closer to 1.300". Because exceptions exist, use the receiver measurement and mounting pattern together when identifying your rifle.
