Unpacking the Core Features of the M400 TREAD

The M400 TREAD is not just another AR-15; it's a meticulously crafted system featuring components optimized for superior function and user experience.

Precision-Engineered 16-Inch Stainless Steel Barrel

At the heart of the M400 TREAD's accuracy is its 16-inch stainless steel barrel. Stainless steel barrels are renowned for their excellent corrosion resistance and superior accuracy potential compared to chrome-lined barrels, often preferred by precision shooters. The 16-inch length is a universally popular choice for AR-15s, striking an optimal balance between maneuverability, velocity, and practical accuracy. This barrel length is particularly effective for delivering consistent performance across various ammunition types, making it suitable for everything from target shooting at the range to varmint hunting in diverse environments. Its quality construction ensures longevity and repeatable accuracy, shot after shot.

Robust 7075 T-6 Aluminum Receiver with Black Hard Coat Anodized Finish

The M400 TREAD’s receiver is constructed from 7075 T-6 aluminum, a high-strength aluminum alloy widely regarded as the industry standard for AR-15 receivers. This material offers an outstanding strength-to-weight ratio, ensuring the rifle is both durable and manageable. The receiver is finished with a black hardcoat anodization. This finish is not merely aesthetic; it provides an extremely durable, scratch-resistant, and corrosion-resistant surface that protects the rifle from the elements and the rigors of heavy use. This robust construction ensures the M400 TREAD can withstand challenging conditions and maintain its operational integrity over a lifetime of use, solidifying its reputation as a dependable choice for personal defense or competitive shooting.

Free-Floating M-LOK Handguard: The Epitome of Modularity

One of the most significant performance-enhancing features of the M400 TREAD is its free-floating M-LOK handguard. Unlike traditional handguards that can contact the barrel and potentially affect accuracy, a free-floating design ensures the barrel remains untouched, allowing it to vibrate consistently and thus improving shot-to-shot precision. The M-LOK system itself is a modern standard for accessory attachment, offering a lightweight and robust solution for mounting lights, lasers, grips, bipods, and other tactical enhancements directly to the handguard. This innovative design provides unparalleled modularity, allowing users to customize their rifle with ease and confidence, adapting it precisely to their specific needs and preferences. Whether you're setting up for low-light operations, competitive shooting, or simply adding a comfortable foregrip, the M-LOK system makes it effortless.

Ergonomic Magpul SL-K 6-Position Telescoping Stock

The inclusion of a Magpul SL-K 6-position telescoping stock further enhances the M400 TREAD's adaptability and user comfort. Magpul is globally recognized for producing high-quality, durable, and ergonomically superior firearm accessories. The SL-K stock is a compact, lightweight, and snag-free option that allows users to quickly adjust the length of pull to suit different body types, shooting stances, or layers of clothing/gear. This adjustability is crucial for maintaining proper shooting form and recoil control, which translates directly to improved accuracy and a more enjoyable shooting experience. Its sleek design minimizes snag points, making it ideal for quick deployment and maneuverability in confined spaces.

Crisp Single Stage Trigger for Enhanced Control

The M400 TREAD comes equipped with a single stage trigger. A single stage trigger is known for its clean break, offering a consistent and predictable trigger pull that many shooters prefer for precision and speed. Unlike two-stage triggers, which have take-up before breaking, a single stage trigger offers a direct pull through to the break, which can aid in rapid follow-up shots and fine-tuning shot placement. This feature contributes significantly to the rifle’s overall shootability, allowing for better accuracy and more confident engagement with targets. For shooters looking to improve their groups or engage targets quickly, a clean-breaking trigger is a distinct advantage.

Versatile 5.56x45mm NATO Caliber with 30+1 Capacity

Chambered in 5.56x45mm NATO, the Sig Sauer M400 TREAD is compatible with both 5.56 NATO and .223 Remington ammunition, offering exceptional versatility and widespread availability of cartridges. This caliber is a staple for AR-15 platforms, known for its flat trajectory, manageable recoil, and effectiveness across a range of distances. The 30+1 round capacity, utilizing a standard AR-15 magazine, ensures ample firepower for training, competition, or defensive scenarios. This common magazine type means users will have no trouble finding additional magazines at DEGuns or other reputable retailers, further enhancing the rifle's practical utility.
