Here's my old Mk 46 Mod 1 preset. I left the bipod off because I've seen pics of SEALs using them without and because it generally makes the gun look sleeker, more (in mall ninja speak) "high speed, low drag".
A
Medal of Honor: Warfighter-inspired M4A1 CQBR build based on Preacher's DDM4 MK18 in the final level.
As you can see here and with the 416 I posted last, I'm switching to darker-colored, high-detail presets for most of my builds.
