• Enhancing Ergonomics: A slimmer, more comfortable profile allows for a more natural grip, reducing fatigue during extended shooting sessions and improving control.
• Expanding Modularity: Modern attachment systems like M-Lok provide abundant, secure points for lights, lasers, foregrips, bipods, and other mission-critical accessories.
• Reducing Weight: Utilizing advanced lightweight materials helps trim ounces, making the rifle easier to handle, especially during rapid transitions or long carries.
• Increasing Durability: Robust construction and superior materials ensure the handguard can withstand the rigors of demanding use, protecting your barrel and gas system.

Whether you're building a new AR-15 from the ground up, or seeking to significantly upgrade an existing rifle, choosing the right handguard is a foundational decision that impacts every aspect of the rifle's performance. The Midwest Industries Combat Rail (SKU: MI-CRM15) is specifically designed to meet these high demands.

Unpacking the Advanced Features of the Midwest Industries Combat Rail

The Midwest Industries Combat Rail stands out in a crowded market due to its meticulously engineered design and high-quality construction. Every feature is thoughtfully integrated to provide maximum benefit to the user.

One-Piece Free-Float Design for Uncompromised Performance

The MI Combat Rail features a single-piece construction, a hallmark of superior handguard design. This unitary structure eliminates potential weak points and ensures exceptional rigidity when mounted. Unlike two-piece designs, a one-piece free-float rail offers:

Patented 4140 Heat-Treated Torque Plate and Barrel Nut

At the heart of the Combat Rail's secure mounting system lies Midwest Industries' patented 4140 heat-treated torque plate, coupled with a matching 4140 heat-treated barrel nut. This is a significant differentiator in terms of long-term reliability and stability.

• 4140 Steel: This is a chromium-molybdenum alloy steel known for its excellent strength-to-weight ratio, toughness, and resistance to fatigue. It is commonly used in critical structural components in various industries, including aerospace and automotive.
• Heat Treatment: Applying heat treatment to 4140 steel significantly enhances its mechanical properties. This process increases the material's hardness, tensile strength, and wear resistance, making the barrel nut and torque plate exceptionally durable and resistant to deformation, even under repeated stress from recoil or harsh handling.
• Patented Torque Plate Functionality: The torque plate is ingeniously designed to interface with the barrel nut, creating an incredibly robust anti-rotation system. This ensures that once the handguard is installed and torqued to specification, it will not rotate or shift under any conditions, maintaining consistent accessory alignment and zero retention for optics. This patented feature provides a level of security and rigidity that is difficult to match.

This robust mounting system guarantees that your handguard remains precisely aligned with your upper receiver, providing a stable platform for optics and accessories, even under the most demanding conditions.

Optimal Length and Lightweight Design

The 15-inch overall length of the Midwest Industries Combat Rail is highly versatile, offering numerous advantages for various shooting applications:

• Extended Grip Area: Provides ample space for an extended support hand grip, promoting better control and stability, especially when shooting from unconventional positions or during rapid-fire sequences.
