I just ordered a Sig RM400 Elite Titanium today. It's only 6.5 pounds, has a full-length MLOC handguard, and a 5.5 pound trigger. I plan to put a Holosun on it. I already have a M400 Enhanced Patrol with all Magpul furniture. They are great rifles. The Tread is their newest rifle; it doesn't have the premium trigger, but still comes with a stainless steel barrel, full-length MLOC handguard and the stock is Magpul. Neither of them come with sights.
