Can a SCAR 17 Switch Barrels from .308 to 6.5 Creedmoor? A Comprehensive Guide

The FN SCAR 17, a highly versatile and popular battle rifle, is known for its adaptability. But can you simply swap its .308 Winchester barrel for a 6.5 Creedmoor? The short answer is no, not directly. While the SCAR 17 platform is modular, a barrel change isn't as straightforward as simply unscrewing one and screwing on another. Let's delve into the specifics.

Understanding the Challenges of a Direct Barrel Swap

The SCAR 17's design, while allowing for some level of customization, doesn't include a simple barrel swap between different calibers. The core issue lies in the chamber dimensions and bolt face. The .308 Winchester and 6.5 Creedmoor cartridges, while both being in the same general size class, have distinct dimensions. Attempting to install a 6.5 Creedmoor barrel designed for a different platform into a SCAR 17 chambered for .308 Winchester would be unsafe and could lead to catastrophic weapon malfunction.

  • Chamber Differences: The chamber is precisely machined to accommodate a specific cartridge. A 6.5 Creedmoor chamber is not interchangeable with a .308 Winchester chamber. Trying to force a round into an incompatible chamber could result in a dangerous situation, including a potentially damaging bulge in the cartridge case or a complete failure to cycle the action.

  • Bolt Face Requirements: The bolt face itself is engineered to match the specific cartridge. The shape and dimensions of the extractor and firing pin are optimized for extracting and igniting the appropriate cartridge. A 6.5 Creedmoor bolt is not compatible with the .308 Winchester bolt in the SCAR 17.

Realistic Options for Caliber Conversion

While a direct barrel swap is not feasible, there are ways to achieve the desired caliber conversion:

  • Purchasing a Factory-Manufactured 6.5 Creedmoor SCAR: The most reliable and safe method is to simply purchase a SCAR 17 already chambered in 6.5 Creedmoor. FN Herstal, the manufacturer, offers this configuration, eliminating any potential issues associated with aftermarket modifications.

  • Professional Gunsmithing: A highly skilled and experienced gunsmith specializing in FN SCAR rifles might be able to perform a caliber conversion. However, this would likely involve extensive modifications, including but not limited to a new barrel, bolt, and potentially other internal components. This should only be done by a professional and is costly and time-consuming. Moreover, the warranty on your weapon is almost certainly void.

Why Consider a 6.5 Creedmoor SCAR?

The 6.5 Creedmoor cartridge offers several advantages over the .308 Winchester, particularly in terms of long-range accuracy and reduced recoil. This makes it a popular choice for precision shooting applications. However, the benefits must be weighed against the added complexity and expense involved in achieving the caliber change.

Conclusion: Safety First!

Modifying firearms requires significant knowledge, skill, and expertise. Improper modifications can lead to serious injury or death. Always prioritize safety and consult with qualified professionals before undertaking any modifications to your firearm. Unless you are purchasing a factory-made 6.5 Creedmoor SCAR 17, switching calibers is not a simple or advisable undertaking.
