Description
Product Overview
The SIG Sauer M400 TREAD is a versatile semi-automatic rifle chambered in 5.56 NATO and compatible with .223 Remington ammunition. Its 16-inch stainless steel barrel uses a mid-length gas system and a three-chamber compensator, while the free-floating M-LOK handguard provides a lightweight platform for mounting accessories. A polished hard-coat single-stage trigger, ambidextrous controls, aircraft-grade aluminum charging handle, and Magpul SL-K six-position telescoping stock give the rifle practical handling and customization options for range use and sporting applications.
