Replacing the handguard on your DPMS LR-308 can significantly enhance its ergonomics, aesthetics, and even performance. This guide provides a step-by-step process, covering everything from choosing the right replacement to completing the installation. Whether you're upgrading for improved comfort, a tactical advantage, or simply a personalized look, this guide will walk you through the entire process.
Understanding Your DPMS LR-308 Handguard
Before diving into the replacement, understanding your current handguard and its attachment method is crucial. DPMS LR-308 rifles typically utilize a free-floating handguard system, meaning the handguard doesn't contact the barrel, contributing to improved accuracy. However, the specific attachment mechanism might vary slightly depending on the year of manufacture and model. Familiarize yourself with your rifle's configuration before proceeding. Consult your owner's manual if necessary.
Identifying Your Handguard Type
Several types of handguards are compatible with the DPMS LR-308 platform. Common types include:
- Standard quad rail: Offers multiple attachment points for accessories.
- Keymod rail: A lighter and more streamlined option with attachment points only where needed.
- M-LOK rail: Similar to Keymod but with a different attachment system.
- Free-floating drop-in handguards: These are generally simpler to install and often more affordable.
Choosing the right replacement depends on your individual needs and preferences. Consider the weight, length, and accessory mounting options when making your selection.
Choosing the Right Replacement Handguard
Selecting the correct replacement handguard is critical for a proper fit and functionality. Ensure the handguard is explicitly designed for the DPMS LR-308 platform. Pay close attention to the specifications, confirming compatibility with your rifle's gas system and barrel nut. Reputable manufacturers clearly state compatible firearm models on their product pages.
Factors to Consider:
- Material: Aluminum is a popular choice for its strength and lightweight properties. Polymer handguards offer cost-effectiveness and reduced weight but may be less durable.
- Length: The handguard's length should complement your shooting style and intended use. Longer handguards offer more real estate for accessories but can increase overall rifle length.
- Rail System: Choose a rail system that's compatible with your existing accessories (e.g., lights, lasers, bipods). Consider whether you prefer a quad rail, Keymod, or M-LOK system based on your needs.
- Weight: A lighter handguard reduces overall rifle weight, improving maneuverability, especially during extended use.
Step-by-Step Handguard Replacement
Once you've selected your new handguard, you can proceed with the replacement. This process typically involves removing the existing handguard and installing the new one. Remember to always prioritize safety and follow proper firearm handling procedures.
Tools You'll Need:
- Appropriate sized wrench(es) for barrel nut removal (This will vary depending on your rifle's specific design)
- Punches (for stubborn barrel nut removal)
- Torque wrench (to prevent over-tightening)
- Possibly a vice block or other stabilizing device
Steps:
- Unloading the Firearm: Ensure your rifle is completely unloaded and clear of ammunition. Visually inspect the chamber and magazine well.
- Removing the Existing Handguard: This process involves removing the barrel nut and any other retaining mechanisms securing the handguard to the upper receiver. Consult your rifle's manual or online resources specific to your model for precise instructions. The process generally involves loosening or removing the barrel nut.
- Installing the New Handguard: Carefully align the new handguard with the upper receiver and install it according to the manufacturer's instructions. This may involve tightening screws or locking mechanisms.
- Tightening the Barrel Nut: Use a torque wrench to tighten the barrel nut to the manufacturer's specified torque. Over-tightening can damage the barrel nut or threads.
- Testing and Inspection: After installation, visually inspect the handguard to ensure it's securely attached and doesn't interfere with the barrel or other components. Test fire the rifle at a safe shooting range to verify proper functionality.
Conclusion
Replacing your DPMS LR-308 handguard is a relatively straightforward process that can drastically improve your shooting experience. By carefully selecting a compatible handguard and following the steps outlined above, you can successfully upgrade your rifle and customize it to better fit your needs. Always prioritize safety, consult your firearm's manual, and seek professional help if you're unsure about any step of the process. Remember to always practice responsible gun ownership.
