The MAS 49/56, a robust and iconic French military rifle, holds a special place in the hearts of firearms enthusiasts. Its sturdy design and reliable action have ensured its continued popularity, even decades after its retirement from front-line service. While originally chambered in 7.5x54mm French, a significant number of these rifles have been converted to fire the more readily available and widely popular .308 Winchester (7.62x51mm NATO) cartridge. This article delves into the intricacies of this conversion, its implications, and the factors to consider before undertaking or purchasing a converted MAS 49/56.
Understanding the Conversion Process
Converting a MAS 49/56 to .308 Winchester is a significant undertaking, requiring specialized gunsmithing skills and knowledge. The process typically involves:
-
Barrel Replacement: The original 7.5x54mm barrel is removed and replaced with a .308 Winchester barrel. This requires precision machining to ensure proper headspace and function. Improperly fitted barrels can lead to dangerous malfunctions.
-
Chamber Modification: The chamber must be re-cut to accommodate the .308 Winchester cartridge. Again, precision is paramount to ensure safe and reliable operation.
-
Magazine Adaptation: While some conversions utilize modified original magazines, others require completely new magazines designed specifically for the .308 Winchester cartridge.
-
Headspace Adjustment: Precise headspace adjustment is critical for safe and reliable operation. Incorrect headspace can lead to catastrophic failure.
Advantages of a .308 Conversion
The primary advantage of converting a MAS 49/56 to .308 Winchester is the readily available ammunition. Finding 7.5x54mm French ammunition can be challenging and expensive, whereas .308 Winchester is widely available at most sporting goods stores and ranges. This increased ammunition accessibility makes the converted MAS 49/56 a more practical and cost-effective option for recreational shooting and collecting.
Disadvantages and Considerations
While the .308 conversion offers benefits, several factors need careful consideration:
-
Headspace Issues: As mentioned earlier, improper headspace is a major concern. A poorly executed conversion can lead to dangerous malfunctions and potential injuries. Only a qualified and experienced gunsmith should undertake this conversion.
-
Reduced Collector Value: Converting a MAS 49/56 significantly reduces its value to collectors who prefer original, unaltered examples. The conversion alters the rifle's historical integrity.
-
Accuracy Potential: While many converted rifles function reliably, the accuracy potential may not always match that of the original cartridge. The bullet's trajectory and performance can differ slightly in the new chamber.
-
Finding a Reputable Gunsmith: The success of the conversion hinges entirely on the skill of the gunsmith. Choosing an experienced and reputable gunsmith specializing in military rifle conversions is crucial.
Choosing a Converted MAS 49/56: What to Look For
If you're considering purchasing a factory-converted or already converted MAS 49/56 in .308, look for the following:
-
Proof of Conversion: Ensure the seller provides documentation or proof that the conversion was performed by a reputable gunsmith.
-
Thorough Inspection: Carefully inspect the rifle for signs of shoddy workmanship, such as mismatched parts or signs of damage.
-
Function Test: If possible, fire a few rounds through the rifle to ensure reliable function and accuracy.
The MAS 49/56 in .308 Winchester offers a unique shooting experience. However, understanding the nuances of the conversion process and carefully considering the potential drawbacks is crucial before making a purchase or undertaking the conversion yourself. Remember, safety should always be the top priority when handling firearms. This conversion should only be performed by a qualified and experienced gunsmith.
