Sig M400 Tread 16" 5.56 Review
The Sig M400 Tread 16" 5.56 is presented as a strong contender in the sub-$1000 AR-15 market, exceeding expectations for an 'entry-level' Sig firearm. It boasts 100% reliability over 1100 rounds, a 16-inch 416R stainless steel barrel with a 1:8 twist, and enhanced ambidextrous controls. The primary drawback is the handguard's tendency to overheat due to a lack of ventilation.
