The Unmatched Legacy of the Remington 700 Action

A Standard Forged in Time

To understand the phenomenon, you must first look at its progenitor: the Remington Model 700 BDL. Introduced in 1962, it didn't just enter the market—it defined it. The Remington Model 700 BDL has no equal, and is a superior performer in every way. It quickly became the standard footprint by which all other centerfire rifles are measured and continually fall short. Its combination of a strong, smooth action, consistent accuracy potential, classic beauty, and unequaled value resonated deeply with hunters and shooters alike, making the Model 700 BDL the hunter's favorite centerfire rifle for over half a century.

This legacy is not sentimental; it's empirical. The Model 700's design—a dual-lug, bolt-face, controlled-round feed system—was a significant leap forward. Its receiver, machined from high-quality steel, provided a rigid platform that could handle increasingly powerful cartridges while maintaining tight tolerances. The strong, smooth action became a benchmark. Hunters from the Alaska frontier to the African plains relied on its dependability, and its accuracy potential, especially in the later ADL and BDL models, was proven time and again on target.

The Foundation of a Custom Revolution

Perhaps the most significant testament to the Remington 700's design is its role in the custom rifle movement. Remington Model 700 actions and receivers have been used as the foundation for custom rifle builds for generations!! Gunsmiths recognized early on that the factory action was not only robust but also highly amenable to modification. Its external and internal dimensions were consistent, and its design allowed for skilled hands to enhance its performance through blueprinting, lapping, and accurizing.

This created a virtuous cycle. As more custom rifles based on the 700 action proved their mettle in competitions and on hunts, demand for the core component soared. The sheer volume of aftermarket parts—stocks, triggers, barrels, bolts, magazines—exploded. They are ready to be turned into that dream rifle. This ecosystem of support is the 700's greatest strength. A builder isn't limited to factory options; they can mix and match from a universe of components to create a truly unique, personalized firearm that meets exact specifications for weight, balance, ergonomics, and ballistic performance.

Why the Remington 700 Action is the Custom Builder's Dream

Modularity and Aftermarket Support

The primary reason for the 700's dominance is its staggering modularity. The platform is available in two primary action lengths: short action (for cartridges like .223 Remington, .308 Winchester, 6.5 Creedmoor) and long action (for cartridges like .30-06 Springfield, .300 Winchester Magnum). Within these, there are further variations (standard, magnum, mini) that affect magazine length and bolt travel. This means you can start with an action perfectly suited to your intended cartridge family.

The aftermarket support is simply incomparable. Companies like McMillan, B&C, KRG, and MDT offer stocks in every conceivable material (laminated wood, synthetic polymer, aluminum chassis) and configuration (sporter, tactical, folding). Trigger groups from Timney, Jewell, and TriggerTech can replace the factory unit for a crisp, light pull. Barrels from Bartlein, Shilen, and Proof Research can be chambered to your exact specs. This means you can replace your wood stock SPS and keep it from getting beat up with a modern, durable chassis system, or install a match-grade barrel for sub-MOA accuracy. The ability to upgrade and customize piece by piece is fundamental to the custom build ethos.

The Engineering Behind the Legend

At its core, the Remington 700 action is a study in functional simplicity and strength. It's a bolt action rifle with a hinged floorplate internal magazine. The bolt features two large locking lugs that engage the receiver, providing a strong breech face. The controlled-round feed design (on most models) guides the cartridge from the magazine into the chamber smoothly, enhancing reliability. The hinged floorplate provides a large, easy-to-use magazine opening for loading and unloading, a feature highly valued in the field.

Markings on original factory actions are part of their identity and legal requirements. Typically, the left side of the barrel is marked “Remington Arms Company Inc Ilion NY [Cartridge].” The left side of the receiver is marked with the serial number and “Remington Model 700.” These markings confirm the action's origin and caliber. It's important to note that there is no provision for iron sights on most modern 700 actions, as they are designed from the ground up for telescopic sight use. The receiver is drilled and tapped for scope bases, a critical feature for any precision-oriented build.

Exploring Modern Variants: Razor and Fusion

While the classic Model 700 BDL and ADL are legendary, Remington (under current ownership) has evolved the platform with modern manufacturing and materials. Two standout families are the Razor and Fusion.

The Razor: A No-Compromise Precision Platform

The Razor family represents Remington's top-tier, precision-focused offering. It's designed for the shooter who demands the highest level of factory performance and a solid foundation for serious custom work. Take your shooting to a whole new level with the Razor and Fusion family of precision bolt actions. These are not just rebranded 700s; they are enhanced from the ground up.

Key features often include a heavy, free-floating barrel, a robust and adjustable trigger system, and a modern, tactical-style synthetic stock with adjustable features. The action is typically polished and smoothed to a high degree, and the overall fit and finish exceed that of standard production models. For a builder, a Razor action provides an excellent "out-of-the-box" performer that can be further tuned or simply used as-is for demanding disciplines like PRS or long-range hunting.

The Fusion: Modern Materials, Classic Reliability

The Fusion line brings modern materials to the trusted 700 platform. Its most notable feature is the polymer synthetic, black & gray finish action and stock. This synthetic construction offers exceptional durability against the elements, scratches, and impacts—a significant advantage over traditional wood. The standard sporter bottom metal type refers to the magazine and trigger guard assembly, which is typically a robust polymer unit that integrates with the stock.

The Fusion is aimed at the hunter and sport shooter who wants the legendary 700 reliability in a more contemporary, low-maintenance package. It's often chambered in popular hunting calibers and comes with a scope already mounted and bore-sighted, making it a complete package. For a custom builder, a Fusion action (or its components) can be a cost-effective way to acquire a modern, stainless-steel action with a durable finish, ready to be paired with an aftermarket stock of choice.

The Importance of Premium Steel: 416R Stainless

Both the Razor and Fusion lines, along with many premium aftermarket and custom actions, are made from premium 416R stainless steel. This is a critical detail. 416R is a martensitic stainless steel specifically designed for gun barrels and actions. It offers excellent machinability, high strength, and superior corrosion resistance compared to standard carbon steels.

Each Razor and Fusion action is made from premium 416R stainless steel. This means the action itself is highly resistant to rust and pitting, a vital feature for rifles used in wet, salty, or harsh environments. For a custom build, starting with a stainless action ensures the core of your rifle will withstand decades of use with minimal maintenance, protecting your investment. It also provides a clean, silver finish that many shooters prefer for its aesthetic and functional qualities.

Where to Find Your Perfect Remington 700 Action

Authorized Dealers and the Aftermarket

Sourcing your action is the first tangible step in your build. You have two primary paths: purchasing a complete rifle to strip for its action, or buying a standalone action/receiver from a parts supplier.

Shop Remington 700 actions at MidwayUSA. MidwayUSA is a premier, reputable dealer for all things firearms and ammunition. They frequently stock standalone actions, complete rifles, and a vast array of parts. Their user-friendly website, competitive pricing, and reliable service make them a top destination. You can often find standard production actions, as well as models from the Razor and Fusion lines, depending on availability.

For specific part numbers and deeper inventories, 430115734 available online at Brownells today and many more rifle receivers & parts products are available in our gun parts department. Brownells is another industry giant, famous for its exhaustive catalog and customer service. The part number mentioned (likely a specific model or variant) is an example of the precise SKUs you can search for. Their "gun parts department" is a treasure trove, offering not just actions but every conceivable component needed for a full build, often with detailed specifications and compatibility notes.

The Used Market and Inspection

Don't overlook the used market. Many gunsmiths and custom shops sell "take-off" actions—essentially new or like-new actions removed from rifles they've built for clients. These can be exceptional values. However, buying used requires diligence.

When inspecting any used Remington 700 action, especially one described as in great shape 45.00 shipped tyd (a common forum/listing shorthand for "in great shape, $45.00 shipped, thanks"), you must be your own quality control. Look for:

• Bolt Movement: The bolt should operate smoothly, with a clean, positive lock-up. Any gritty feeling or excessive play is a red flag.
• Receiver Face: Check for cracks, pitting, or excessive wear where the bolt lugs contact.
• Threads: Ensure the barrel threads (if already threaded) are clean and undamaged.
• Magazine Well: Inspect for deformation or damage.
• Serial Number: Verify it is present and legible on the receiver. Be cautious of any signs of alteration.

Practical Considerations: Policies, Parts, and Your Build

Understanding Return and Inspection Policies

When purchasing a firearm component, especially online, understanding the seller's policy is crucial. Reputable dealers stand behind their products. For example, a listing might state: We gladly offer a 3 day unfired inspection policy from the time that the firearm is delivered to your FFL. Refunds are available for all qualifying. This is a significant buyer protection.

A 3-day unfired inspection policy means that once your local Federal Firearms License (FFL) dealer receives the package, you have three business days to inspect the action (or rifle) for any defects or damages not apparent in online photos. You can refuse the transfer to the FFL if it's not as described, initiating a return. Refunds are available for all qualifying returns, typically covering the purchase price but not necessarily return shipping. Always read the specific terms, but such a policy from a major retailer like Brownells or MidwayUSA provides immense peace of mind.

Bottom Metal and Stock Configurations

Your choice of stock and bottom metal (the trigger guard and magazine floorplate assembly) dramatically affects the rifle's ergonomics and performance. The standard sporter bottom metal type is what comes on most factory Model 700s. It's functional and durable but often the first component replaced in a serious custom build to save weight or accommodate a different magazine system (like AICS or Accuracy International magazines).

The BDL / hinged floorplate is a classic feature. The hinged floorplate allows the magazine to be opened by pushing a release, providing a large opening for easy loading and unloading. This is a beloved feature for hunters. If you source a BDL model action, this floorplate is included and is a high-quality, blued steel part. You can often use this factory floorplate with aftermarket stocks that are cut for the BDL pattern, maintaining that classic functionality.

The Polymer Finish and Modern Upgrades

As mentioned, modern variants like the Fusion use a polymer synthetic, black & gray finish action. This is a durable, matte-finish coating applied to the steel action. It's highly resistant to corrosion and scratches, requiring little more than a wipe-down. For a builder who plans to use the rifle in rugged conditions or simply prefers a modern, non-reflective look, this is a major advantage over a traditional blued finish.

Replace your wood stock SPS—this advice points to one of the most common and impactful first upgrades. The factory SPS (Special Purpose Synthetic) stock on many modern 700s is functional but often flexes under load, hurting accuracy. Upgrading to a rigid, adjustable aluminum chassis or a high-quality laminated stock can dramatically improve accuracy potential and customize the rifle's fit to your body. This is where the modularity of the platform truly shines.

Conclusion: Building Your Legacy on a Legend

The journey of building a custom rifle is deeply personal. It's about crafting a tool that is an extension of your own skill and intent. At the center of that journey, more often than not, sits a Remington 700 action. Its history is not a museum piece; it's a living, breathing foundation for innovation. From the classic lines of the Model 700 BDL that set the world standard to the modern engineering of the Razor and Fusion families built from premium 416R stainless steel, this platform has continuously evolved while maintaining its core identity.
