Steel Picatinny base for Remington 700 Long Action. The UTG MNT-RM700 provides a defined Picatinny interface for compatible scope rings and mounts. The key point when buying is the action length: Long Action and Short Action are not interchangeable.

Our honest assessment
If you're looking for a simple, robust steel base for a Remington 700 Long Action system, this is a straightforward solution with six Picatinny slots and a central ejection cutout. It forms the base of your optic setup—not a complete mount with rings.
A good fit / probably not a good fit


A good fit if …
your rifle is definitely a Remington 700 Long Action,
you want to use Picatinny-compatible rings or mounts,
a robust steel base matters more to you than minimal weight.



Probably not a good fit if …
you have a Remington 700 Short Action,
you're looking for a base with a defined forward incline,
you expect rings or a complete optic mount to be included.



Practical benefits


6 Picatinny slots Three at the front and three at the rear provide defined positions for rings and help you adjust eye relief.


Central cutout The action area remains open for ejection and operation, rather than being unnecessarily covered by a continuous full-length rail.


Limitations, drawbacks & how to avoid a bad purchase

Verify that you have a Long Action before ordering.
Choose ring height only after considering the base, optic, objective lens, and your natural head position.
Steel is robust, but heavier than many aluminum options.
The mounting base, rings, and optic form a system; a compatible base alone doesn't guarantee an ergonomic shooting position.

FAQ
Does the
Base for a short action? No. This version is designed for the Remington 700 Long Action. Are rings included? No. The Picatinny base is the interface; compatible rings are selected separately. Why the cutout in the middle? To keep the action area clear for ejection and operation. What ring height do I need? That depends on the optic, objective lens, stock, and your natural head position—not just the objective lens diameter.
Black-Raptor verdict: a robust base for a clearly identified Remington 700 Long Action. The most common mistake isn’t the brand, but choosing the wrong action length or failing to plan ring height properly.
