How to Choose the Right 12.7×42 50 Cal AR-15 Upper Assembly

Choosing the right 12.7×42 50 cal AR-15 upper assembly involves several key factors. Let’s break them down:

Compatibility

First and foremost, ensure that the upper assembly is compatible with your AR-15 lower receiver. Most 12.7×42 uppers are designed to fit mil-spec AR-15 lowers, but it’s always good to double-check.

• Buffer System: Consider adding a heavier buffer to your setup. This helps manage the recoil from the powerful 50 Beowulf round.
• Bolt Carrier Group (BCG): Typically, a 6.5 Grendel Type 2 BCG is recommended. However, some manufacturers might use a different type, so verify before purchasing.

Budget

Budget is another crucial factor. Prices for 12.7×42 uppers can vary widely, from around $550 to nearly $900, depending on features and quality.

• Basic Models: If you’re on a tight budget, basic models offer good performance without breaking the bank. These usually include standard features and materials.
• Premium Models: Higher-end models offer superior materials, additional features, and better customization options. These are ideal if you want the best performance and durability.

Intended Use

Understanding your intended use will help you choose the right upper assembly.

• Hunting: If you’re hunting large game like deer or moose, opt for an upper with a longer barrel (around 16 inches) for better accuracy and range.
• Personal Defense: For home defense or close-quarters combat, shorter barrels (7.5 to 10.5 inches) are more maneuverable.
• Recreational Shooting: If you’re into plinking or range shooting, a mid-range barrel length (around 10.5 inches) offers a good balance between accuracy and maneuverability.

Quality Control

Quality control can make or break your shooting experience. Look for uppers made from high-quality steel and aluminum to ensure durability and performance.

• Manufacturing Standards: Ensure the upper assembly meets mil-spec standards. This guarantees compatibility and reliability.
• Brand Reputation: Choose brands known for their rigorous quality control processes. Reading reviews and doing some research can help you make an informed decision.

By considering these factors, you can select the perfect 12.7×42 50 cal AR-15 upper assembly that meets your needs and preferences. Whether you’re hunting, defending your home, or just enjoying some range time, the right upper assembly makes all the difference.

Next, we’ll dig into installation and maintenance tips for your 12.7×42 50 cal AR-15 upper assembly, including how to ensure compatibility and reduce recoil.

Installation and Maintenance Tips

Installing and maintaining your 12.7×42 50 cal AR-15 upper assembly is crucial for optimal performance and longevity. Let’s go through some essential tips to help you get started.

Mil-Spec AR-15 Lowers

First off, ensure your 12.7×42 50 cal AR-15 upper assembly is compatible with mil-spec AR-15 lowers. This ensures a secure fit and reliable operation. Mil-spec lowers are standardized, making them the best choice for most upper assemblies.

Heavier Buffer for Recoil Reduction

Given the high stopping power of the 12.7×42 caliber, managing recoil is essential. Adding a heavier buffer can significantly reduce recoil, making your shots more manageable and improving accuracy.

• Standard Buffer: Typically weighs around 3 ounces.
• H2 Buffer: Weighs about 4.6 ounces and is recommended for reducing recoil.
• H3 Buffer: Heavier at 5.6 ounces, offering even more recoil reduction.

The heavier buffer absorbs more of the recoil energy, making your shooting experience more comfortable.

Regular Cleaning

Regular maintenance is key to keeping your firearm in top condition. Here’s a quick guide on how to clean your 12.7×42 50 cal AR-15 upper assembly:

1. Disassembly: Remove the upper from the lower receiver. Take out the bolt carrier group (BCG) and charging handle.
2. Cleaning the Barrel: Use a bore brush and solvent to clean the barrel. Follow up with patches until they come out clean.
3. Bolt Carrier Group: Clean the BCG with solvent and a brush. Pay attention to the bolt, firing pin, and cam pin.
4. Gas System: Ensure the gas block and tube are free of carbon buildup.
5. Lubrication: Apply a light coat of lubricant to the moving parts, especially the BCG and charging handle.
6. Reassembly: Put the upper back together and reattach it to the lower receiver.

Regular cleaning not only ensures reliability but also extends the life of your firearm.

Additional Tips

• Use Proper Tools: Always use the right tools, like an Armorer’s Wrench and Roll Pin Punch Set, to avoid damaging your firearm.
• Safety First: Always ensure the firearm is unloaded before starting any maintenance work.
• Check for Wear and Tear: Regularly inspect parts for any signs of wear or damage. Replace parts as needed to maintain performance.

By following these installation and maintenance tips, you can ensure your 12.7×42 50 cal AR-15 upper assembly performs reliably and lasts for years to come.

Frequently Asked Questions about 12.7×42 50 Cal AR-15 Upper Assemblies

Is 12.7×42 the same as 50 Beowulf?

Yes, 12.7×42 and 50 Beowulf refer to the same cartridge. The 12.7x42mm is the metric designation, while 50 Beowulf is the more commonly used name. Both names describe the same powerful, short-range caliber designed for the AR-15 platform. This round is known for its impressive stopping power and is effective for hunting large game like deer, moose, and black bear.

Does 50 Beowulf fit a 223 upper?

No, a 50 Beowulf upper will not fit directly onto a standard .223/5.56 lower receiver without some modifications. The 50 Beowulf upper is specifically designed to accommodate the larger 12.7x42mm cartridge, which requires a different bolt carrier group (BCG) and magazine. Most 50 Beowulf uppers use a 6.5 Grendel Type 2 BCG, although some manufacturers may use the 6.5 Grendel Type 1 (7.62×39) BCG. It’s crucial to use a 50 Beowulf magazine to ensure proper feeding of the larger rounds.

What is the effective range of a 50 Beowulf?

The effective range of a 50 Beowulf upper is generally up to 200 yards. This range makes it ideal for short to medium-range engagements, whether you’re hunting large game or using it for personal defense. Within this range, the 400-600 grain projectiles deliver tremendous stopping and penetrating power, making it a formidable choice for close-quarters scenarios.

By understanding these frequently asked questions, you’ll be better equipped to make informed decisions about your 12.7×42 50 cal AR-15 upper assembly.
