Egw Mosin Nagant 91/93 1-Piece Undrilled Picatinny Base 0 Moa
$80.99
The EGW Mosin Nagant 91/93 1-piece Picatinny base is a no-drill, no-solder mounting solution for shooters who want to modernize their classic rifle without permanent modification. This undrilled base leverages the existing rear sight housing as its foundation, letting you keep the original pin and avoid the irreversible work that comes with some aftermarket mounts. It's a straightforward way to add optics to a Mosin—whether you're hunting, running it at the range, or building a modern-era battler out of a Soviet-era platform.
Installation uses the rifle's original rear sight pin and a simple set screw that takes up play in the rail, so you don't need special tools or gunsmithing experience. The mount ships undrilled, giving you the flexibility to fit it to your specific receiver; EGW recommends confirming your hole spacing against their published dimensions before final installation. Once seated, the full-length Picatinny cross slots let you position scope rings anywhere along the rail, and the recessed center channel keeps weight down without obstructing factory iron sights in most cases—useful if you want to keep backup irons in the fight.
EGW machines these bases in-house on precision machining centers, then tumbles, sand-blasts, and Type III anodizes every piece for lasting durability in the field. The solid steel construction pairs with an aluminum top mount that handles repeated mounting cycles. As a 0 MOA base, it sits flat—no built-in elevation—so all zero adjustment happens at the rings or your optic itself.

Frequently Asked Questions
Do I need to drill my Mosin Nagant receiver to install this base?
No. This is an undrilled base that uses your rifle's existing rear sight housing and the original pin, so no drilling or permanent modification is required. EGW recommends measuring your receiver's hole spacing against their published dimensions to confirm fitment before installation.
Will this mount work with factory iron sights?
In many cases, yes. The recessed center channel in the mount reduces its overall profile, which often leaves your factory iron sights usable. Fitment can vary by specific rifle, so checking the base against your receiver before final installation is a good idea.
What tools and supplies do I need to install it?
EGW recommends applying 20 inch-pounds of torque when tightening and using a small amount of blue Loctite on the fasteners (sold separately). A basic set of gunsmith screwdrivers and a torque wrench are all you need for installation.
Can I mount this base in either direction?
Yes. The mount can be installed in either direction on the rifle, giving you flexibility in how you position your scope rings and optics relative to your receiver and stock.
