Primary Weapons Systems MK107 MOD-1 upper. Long-stroke piston, 7.75" barrel, .223 Wylde, 3 position gas regulator, Radian Raptor LT charging handle.
Approximately 100 rounds fired and it has been perfect. I bought this as a blem from PWS which still has their lifetime warranty.
$725 for complete upper only
