Description
The Sig Sauer M400 TREAD is a step in the right direction when it comes to entry level AR15 platform pistols. It utilizes a pistol-length direct impingement operating system with a SIG Microlite Gas Block. The upper and lower receiver of rifle are made from aircraft grade 7075 aluminum and have been hardcoat anodized for long lasting durability.
The Sig Sauer M400 TREAD features a full length handguard that is free floated and has lightning cuts for heat ventilation. The handguard features Magpul’s MLOK attachment points that reduces overall weight and gives the M400 TREAD a clean no-nonsense look. The lower receiver features ambidextrous safety controls and bolt release. The barrel of the rifle is made from stainless steel, uses a natural stainless finish, and is crowned with a flashhiding compensator. The Sig Sauer M400 TREAD Pistol is one of the finest entry level AR15 pistols available, with features usually not found on pistols at its price point. Don't forget to pick up an optic too - any reflex sight, holographic sight, or low power scope would make a great addition to this rifle!
