Egw Montana Rifle 1999 Long Action Hd Scope Base 20 Moa

The EGW Montana Rifle 1999 Long Action HD scope base with 20 MOA is a precision one-piece aluminum mount built for shooters who want rock-solid optics placement on their long-action rifle. If you're running a scope on a Montana 1999 and need the extra elevation correction that a 20 MOA base provides—whether for long-range hunting, precision rifle work, or high-distance shooting—this American-made base gives you the foundation to dial in accurately without burning up your scope's internal adjustment range.

Machined from solid 7075 T6 aircraft-grade aluminum and finished in matte black, this mount is built to handle repeated shooting without shifting. The base features full-length Picatinny rails gauged to military spec (MIL-STD 1913), so you have the flexibility to mount standard Picatinny or Weaver rings exactly where you need them. A beveled design on both sides makes the base ambidextrous, and the Picatinny cross slots run the full length and width of the mount, opening up options for ring placement and accessory mounting. Type III hard-coat anodizing on the aluminum and mil-spec parkerizing on the steel rails ensure durability in the field.

Installation is straightforward with included #6-48 X 1/4 screws, a T-10 bit, and clear torque specs (20 inch-lbs recommended). A drip of blue Loctite—sold separately—secures everything permanently. Made entirely in the USA from machining through packaging, this is the kind of mount that lets you focus on precision rather than worrying about your scope shifting between shots.

Frequently Asked Questions

What scope rings do I need for this base?

This mount accepts any standard Picatinny or Weaver scope rings. The full-length Picatinny cross slots give you flexibility in ring placement along the rail.

What's included in the box?

The base comes with #6-48 X 1/4 mounting screws and a T-10 bit for installation. You'll need a small amount of blue Loctite (sold separately) to secure the screws permanently, and scope rings to complete the setup.

How tight should I tighten the mounting screws?

EGW recommends applying 20 inch-lbs of torque to the mounting screws. Use a torque wrench to hit that spec consistently—over-torquing can damage the receiver or base, and under-torquing leaves room for shift.

Will this work on other rifle platforms?

This base is specifically designed for the Montana Rifle 1999 Long Action. Always verify receiver compatibility before purchasing a scope base for any rifle.
