final verdict
“The Sig Sauer M400 Tread AR-15 is a great mid-level rifle that packs an upgraded handguard and pistol grip. The mil-spec trigger is decent and since it’s an AR there’s limitless further upgrade potentials. Reliability has been great and the price also offers great bang-for-the-buck. If you’re looking to get into the AR-15 game this is a great pick for your first or even second rifle.” – Ken Whitmore
