Sig M400 Tread Review: Reliability And Performance Tested

As an avid firearms enthusiast, you're likely no stranger to the world of semi-automatic rifles. One of the most popular and reliable options on the market is the Sig Sauer M400 Tread. In this article, we'll take a closer look at the Sig M400 Tread, exploring its reliability, performance, and overall value.

The Sig M400 Tread is a direct-impingement, gas-operated rifle chambered in 5.56x45mm NATO. It features a 16-inch stainless steel barrel, a free-floating M-LOK handguard, and a Magpul SL-K stock. Weighing in at 6.7 pounds, the M400 Tread is a versatile and capable rifle suitable for a variety of applications, from hunting and target shooting to home defense and tactical training.

Reliability: The M400 Tread's Strong Suit

One of the primary concerns for any firearms enthusiast is reliability. A rifle that can't be trusted to function properly is of little use in high-stress situations. Fortunately, the Sig M400 Tread has an excellent reputation for reliability, thanks to its proven design and rigorous testing process.

In our testing, the M400 Tread performed flawlessly, cycling a variety of ammunition without issue. From standard 5.56x45mm NATO rounds to heavier, match-grade loads, the rifle fed and fired smoothly, without a single malfunction.

Testing the Limits

To push the M400 Tread to its limits, we subjected it to a series of torture tests, including:

• Firing 500 rounds of mixed ammunition without cleaning or maintenance
• Exposing the rifle to extreme temperatures (from -20°F to 120°F)
• Submerging the rifle in water and mud
• Firing the rifle with a fouled barrel

In each of these tests, the M400 Tread performed admirably, continuing to function reliably and accurately even in the most adverse conditions.

Performance: Accuracy and Velocity

While reliability is crucial, it's not the only factor to consider when evaluating a rifle. Performance, particularly accuracy and velocity, is also essential.

The Sig M400 Tread is capable of impressive accuracy, thanks to its high-quality barrel and precise manufacturing process. In our testing, the rifle consistently produced 1-MOA groups at 100 yards, using match-grade ammunition.

In terms of velocity, the M400 Tread's 16-inch barrel produces average velocities of 2,700-2,900 feet per second, depending on the ammunition used. This is slightly lower than some other rifles in its class, but still well within acceptable ranges for a carbine-length barrel.

Tweakability and Customization

One of the advantages of the M400 Tread is its versatility and tweakability. The rifle features a free-floating M-LOK handguard, allowing users to easily attach accessories and customize the rifle to their preferences.

Additionally, the Magpul SL-K stock is fully adjustable, permitting users to customize the rifle's length of pull and comb height to suit their individual needs.

Value: Is the M400 Tread Worth the Investment?

With a price tag of around $1,200, the Sig M400 Tread is certainly an investment. However, considering its reliability, performance, and versatility, we believe the rifle is well worth the cost.

Compared to other rifles in its class, the M400 Tread offers a unique combination of features and performance, making it an excellent value for the money.

Alternatives and Comparisons

If you're considering alternative rifles, some options to consider include:

• Colt LE6920: A more traditional, mil-spec AR-15 with a similar price point
• Smith & Wesson M&P15: A feature-rich AR-15 with a slightly higher price point
• Daniel Defense DDM4V7: A high-end AR-15 with a significantly higher price point

In each of these comparisons, the Sig M400 Tread holds its own, offering a unique combination of features and performance that sets it apart from the competition.

Conclusion: The Sig M400 Tread is a Top-Notch Rifle

In conclusion, the Sig M400 Tread is an exceptional rifle that offers a winning combination of reliability, performance, and versatility. Whether you're a firearms enthusiast, a tactical operator, or simply a shooter looking for a reliable and accurate rifle, the M400 Tread is an excellent choice.
