The 6.5 Grendel cartridge has rapidly gained popularity among shooters and hunters, known for its impressive accuracy and effective range. A complete upper receiver, especially one featuring a 20-inch barrel, significantly enhances the capabilities of an AR-15 platform. This detailed guide explores the advantages of a 6.5 Grendel complete upper with a 20-inch barrel, highlighting key considerations for potential buyers.
Why Choose a 20-Inch 6.5 Grendel Barrel?
The 20-inch barrel length offers several key benefits for the 6.5 Grendel round:
-
Increased Velocity and Energy: Longer barrels allow for more complete powder burn, resulting in higher muzzle velocity and greater downrange energy. This translates to extended effective range and improved ballistic performance compared to shorter barrels. This is crucial for long-range shooting and hunting applications.
-
Improved Accuracy: A longer barrel contributes to enhanced accuracy by providing a more stable platform for the bullet to exit. The longer the barrel, the more consistent and precise the shot grouping is likely to be.
-
Flatter Trajectory: Higher muzzle velocity provided by the longer barrel leads to a flatter trajectory, meaning less bullet drop over distance. This simplifies aiming and reduces the need for significant trajectory compensation at longer ranges.
-
Reduced Recoil: While counterintuitive, a longer barrel can sometimes slightly reduce felt recoil in certain calibers due to more efficient powder burn and momentum transfer.
Key Features to Look For in a 6.5 Grendel Complete Upper (20-inch Barrel)
When selecting a 6.5 Grendel complete upper with a 20-inch barrel, several crucial features should guide your decision:
Barrel Material and Profile:
-
Material: High-quality barrels are typically made from chrome-moly vanadium steel (CMV) or stainless steel. Stainless steel offers superior corrosion resistance, while CMV provides excellent strength and accuracy.
-
Profile: Barrel profiles (e.g., mid-length, heavy profile) influence weight, heat dissipation, and stiffness. A heavier profile barrel will generally be more accurate but heavier to carry. Consider the intended use – a heavier profile is better suited for long-range shooting, while a lighter profile is preferred for maneuverability in closer-quarters situations.
Gas System:
-
Mid-length Gas System: This is a popular choice for 6.5 Grendel uppers, providing a balance between reliability and reduced recoil.
-
Carbine-length Gas System: Offers faster cycling but may contribute to increased recoil.
Handguard:
- Length and Material: Ensure the handguard adequately protects the barrel and provides sufficient mounting points for accessories. Consider materials like aluminum for durability and heat dissipation.
BCG (Bolt Carrier Group):
- Material and Finish: Opt for a BCG made from high-quality materials with a robust finish to ensure longevity and reliability.
Considerations Before Purchasing
Before investing in a 6.5 Grendel complete upper with a 20-inch barrel, consider the following:
-
Intended Use: Are you primarily interested in long-range target shooting, hunting, or a combination? Your intended use will influence the choice of barrel profile, gas system, and other features.
-
Budget: Complete uppers vary significantly in price. Set a realistic budget before beginning your search to avoid impulse purchases.
-
Compatibility: Ensure the upper receiver is compatible with your existing lower receiver.
Conclusion
A 6.5 Grendel complete upper with a 20-inch barrel offers a compelling combination of accuracy, range, and performance. By carefully considering the factors discussed above, you can choose a setup that meets your specific needs and budget, allowing you to fully experience the capabilities of this versatile cartridge. Remember to always prioritize safety and follow proper firearm handling procedures.
