SIG SAUER RM400-16B-TRD-V2G M400 5.56MM TREAD V2

The SIG SAUER RM400-16B-TRD-V2G is a SIGM400 TREAD V2 semi-automatic rifle chambered in 5.56 NATO. The suffix “V2G” designates the Moss Green finish. It is built on the AR-15 platform and is intended for sporting, recreational, and defensive use where lawful. The TREAD V2 updates the original M400 TREAD with several upgraded features, including an improved trigger, enhanced controls, and furniture.

Specifications

Key Features

• 16-inch stainless steel barrel with a 1:8 twist, suitable for a wide range of common 5.56/.223 bullet weights.
• Mid-length gas system, which generally provides smoother cycling than a carbine-length system.
• Free-floating M-LOK handguard for mounting compatible accessories and helping maintain barrel consistency.
• Matchlite Duo two-stage trigger, offering a lighter, more defined trigger break than a typical mil-spec trigger.
• Ambidextrous safety selector and magazine release.
• Threaded muzzle fitted with a SIG three-prong flash hider.
• Full-length Picatinny top rail for mounting optics.
• Magpul SL-K adjustable stock for length-of-pull adjustment.

Ammunition

The rifle is chambered for 5.56 NATO, allowing it to safely fire:

• 5.56×45mm NATO
• .223 Remington

As with any firearm, use quality ammunition that matches the manufacturer’s recommendations.

Accuracy

The free-floating barrel, two-stage trigger, and mid-length gas system contribute to good practical accuracy. Many shooters report the platform is well suited for recreational target shooting and competition, though results depend on ammunition, optics, and shooter skill.

Controls

• Ambidextrous safety
• Ambidextrous magazine release
• Standard AR-pattern charging handle
• Bolt catch/release on the left side
• Adjustable Magpul stock

These controls make the rifle usable by both right- and left-handed shooters.

Included Equipment

Depending on the retailer and jurisdiction, the package typically includes:

• SIGM400 TREAD V2 rifle
• One 30-round magazine (or a reduced-capacity magazine where required by law)
• Owner’s manual
• Cable lock
• Hard case or box packaging

Advantages

• Lightweight AR-15 pattern rifle.
• Stainless steel barrel for durability and corrosion resistance.
• Mid-length gas system for smoother recoil impulse.
• Factory two-stage trigger.
• Free-float M-LOK handguard.
• Ambidextrous controls.
• Compatible with many standard AR-15 accessories and optics.

Considerations

• Ships without iron sights or an optic, so you’ll need to add aiming equipment before use.
• The included magazine capacity varies depending on local laws.
• Regular cleaning and lubrication help maintain reliable performance, particularly with direct-impingement AR-pattern rifles.

Typical Applications

The SIGM400 TREAD V2 is commonly used for:

• Recreational target shooting
• Practical shooting competitions
• Hunting where legal and appropriate for the game being pursued
• Home or property defense where lawful and with appropriate training

Comparison to the Original M400 TREAD

The TREAD V2 is generally regarded as a meaningful upgrade over the original model, particularly because of its improved trigger, enhanced ergonomics, and ambidextrous controls.
