This receiver is the heart of your build. It’s engineered for the extended magazine box and bolt face of the powerful Ultra Magnum family. The real value here is in the flexibility—you’re not paying for a factory barrel you might replace anyway. Instead, you can pair it with a premium aftermarket barrel from brands like Proof Research or Criterion, and a trigger from Timney or TriggerTech. The total weight of your finished rifle will depend entirely on your component choices, but starting with this stainless receiver adds a solid, reliable base. Remember, an FFL transfer is required for firearm purchases like this receiver.
Who This Receiver Is For
This is for the hands-on shooter who views a rifle as a sum of its parts. It’s perfect for the budget-minded long-range enthusiast wanting a .300 RUM or .338 RUM hunting rifle without the $1,200+ price tag of a complete model. It’s also ideal for experienced builders who trust specific aftermarket parts over factory offerings. If you enjoy the process and want a rifle no one else has, this is your starting block.
Pros & Cons
Pros: Significant cost savings versus a complete rifle. Total customization control. Durable stainless steel construction. Compatible with a massive ecosystem of Remington 700 aftermarket parts. A practical project that teaches you how your rifle works.
Cons: Requires additional investment in barrel, stock, trigger, and gunsmithing for assembly. Not a ready-to-shoot firearm. You need technical knowledge or a trusted gunsmith. The final cost will exceed the receiver price—that’s the tradeoff for customization.
Frequently Asked Questions
Q: What parts do I need to complete a rifle using this receiver?
A: You’ll need a barrel chambered for your chosen Ultra Magnum cartridge, a barrel nut and recoil lug (if pre-fit), a bolt assembly, a trigger, a stock or chassis, bottom metal, and a magazine. It’s a project, but each part is an opportunity to optimize for your needs.
Q: Is this compatible with standard Remington 700 long action stocks?
A: Here’s the thing—while the action screw spacing is standard, the Ultra Magnum has a longer magazine box. You’ll need a stock or chassis inlet specifically for the “Ultra Mag” or “Magnum” action length, not just a standard long action. Always verify compatibility with the stock manufacturer.
Q: Can I use this for calibers other than .300 RUM or .338 RUM?
A: The bolt face and magazine length are designed for the large rim and overall length of the RUM family. While a skilled gunsmith could potentially modify it, it’s not cost-effective. This receiver is purpose-built for those high-power cartridges, which is why it’s a niche but valuable find at this price point.
