I’m pretty sure I am one of the first to order and receive the new M5E1 upper with the 15in Mono type rail. Got it on their prerelease sale. Gonna order up the M5 lower soon. Got a 16in SS rainier arms barrel with mid gas and PWS FSC30 Break. Going with a JP buffer, Geissele SD-E, BADASS short throw ambi. About does it, will be used for 3gun heavy metal with troy ak irons. May get a SWFA 3-15 a bit later for a hunting rig.
I load a lot with my 650 and will be getting some dies soon. have a bunch of AA2460 for 5.56 that will work on the 308.
