This unit is the heart of the rifle. It includes the barreled action, trigger, and bolt. You’ll need to source a compatible stock or chassis system, along with optics and rings. The good news? The Remington 700 pattern is the most supported action in the world. That said, building around this action lets you control cost and quality at every other step, often resulting in a better rifle for the money than buying off-the-rack.
Who This Is For
This is for the budget-conscious shooter who wants a true custom rifle but needs to spread the cost over time. It’s perfect for the long-range enthusiast, the serious hunter pursuing elk or moose, or the tinkerer who enjoys the build process. If you appreciate the 700’s reliability but want to bypass parts you’d replace anyway, this barreled action is your smart starting point. It’s available at firearms-missouri.com for Missouri residents and nationwide.
Pros & Cons
Pros: Exceptional value for a proven, accurate action. The adjustable X-Mark Pro trigger is a genuine improvement and fits out of the box with most 700-pattern stocks. Massive aftermarket means endless customization. Lets you build a premium rifle on a practical budget. Saves you from paying for a factory stock you might discard.
Cons: Not a complete rifle—requires additional investment for stock, bottom metal, and optics. Final weight depends heavily on your stock/chassis choice, but the carbon steel construction provides a solid base. You’re responsible for the final assembly, though it requires minimal gunsmithing.
Frequently Asked Questions
Q: What exactly do I get, and what else do I need to buy?
A: You receive the barreled action (receiver, barrel, bolt) with the X-Mark Pro trigger installed. To complete a functional rifle, you will need a Remington 700 long action stock or chassis system, a scope base (likely 1-piece Picatinny), scope rings, an optic, and ammunition. A bipod and sling are also common additions.
Q: Is the trigger really adjustable?
A: Yes. The X-Mark Pro trigger is user-adjustable for pull weight within a safe range using a simple hex key. This allows you to fine-tune the break to your preference, a feature typically found on much more expensive factory rifles or aftermarket triggers.
Q: What’s the main advantage over buying a complete Remington 700 rifle?
A: Cost control and customization. A complete magnum rifle often costs $200-$400 more. By starting here, you avoid paying for a factory stock you may not want. You can immediately invest that saved money into a higher-quality stock or chassis from a brand like Magpul or a premium optic, directly improving performance.
Look, if you’ve been planning a magnum-caliber build for long-range target shooting or hunting big game, this Remington 700 Long Action Magnum Carbon Steel action is the most cost-effective way to start with a trusted platform. It delivers the core accuracy and reliability of the 700 design while letting you build the exact rifle you want, piece by piece. FFL transfer required for firearm purchases.
