Steel Blocks: Steel AR-15 barrel vise blocks represent the top tier in terms of strength and durability. These blocks can withstand the highest levels of torque and are ideal for professional gunsmiths or individuals who anticipate frequent or demanding use. However, steel blocks are typically the most expensive option.
Considering the Design
Beyond the material, consider the vise block’s design:
Clamshell/Split Design: This design clamps around the barrel, providing a secure grip. They are generally easier to use than solid blocks and are often a good choice for beginners.
Solid Block Design: These blocks are typically a single piece, which offers excellent stability. However, they may require more effort to install the barrel.
Receiver Extension Blocks: Some vise blocks are designed to accommodate the receiver extension. They provide additional support during removal of barrel nuts and other tasks.
Essential Characteristics to Seek Out
No matter the type, always seek a vise block with the following features:
Proper Fit: The block must be compatible with your AR-15 barrel profile. Standard, heavy, and other specialized barrel profiles will need appropriately designed blocks. The fit should be snug and secure.
Durability: The vise block should be constructed from materials that can withstand the forces involved in gunsmithing. It should be robust enough to handle repeated use without damage.
Non-Marring Surfaces: The barrel is a precision component and needs to be handled carefully. Ensure that the vise block utilizes non-marring surfaces, such as polymer or rubber inserts, to prevent scratches or damage to the barrel’s finish. This helps maintain the value and performance of your firearm.
Mounting Flexibility: The block needs to be easily mounted to your bench vise. Check for design characteristics like compatibility with pins or a direct clamping mechanism.
Gathering Your Gear: Tools and Supplies
Before you begin, make sure you have all the necessary tools and materials. Having everything at hand will make the process much smoother.
The Essentials
The AR-15 barrel vise block (of course!)
Bench Vise: A sturdy bench vise is crucial for providing a stable platform. Ensure the vise is large enough to accommodate the vise block.
