The Sig Sauer M400 TREAD Pistol is a step in the right direction when it comes to entry level AR15 platform pistols. The pistol utilizes a direct impingement operating system and comes standard with features usually only found on premium priced pistols. 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 pistol 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 3 prong flash hider. If you're in the market for your first AR15 or just looking for an upgrade at a great price point, the M400 TREAD will undoubtedly exceed your expectations. Don't forget to pick up an optic too! A reflex sight or low power variable scope would compliment the rifle incredibly well.

Features of the Sig Sauer M400 TREAD

  • Flush Cup built into receiver for single point slings
  • Ambidextrous Controls accommodate left handed shooters
  • Full Length Handguard to accommodate all support-hand positions
  • MLOK Attachment Points at the 12, 3, 6, and 9 o’clock positions on handguard
  • Blade 2.0 Pistol Brace provides a comfortable and customizable fit.
