The new Inception feednecks look great. Also did an Empire one using the Inception stem.
PnueMag, xvalve,Ule body, Luke's rail, CCM feedneck, rt on/off, Rpg detent, CP foregrip, $320 shipped and pp. May need some tuning, dry fires as it should.
No pre orders, I've already spent too much money to worry about it.
