So I have decided to go with YHM lower and had orginally planned to do a BCM upper but I have been browsing and came across YHM uppers. I played with some numbers and found that I could get a YHM upper for around $775 which includes there quad rail, flip ups front and rear, BCG, and charging handle (I would also have a matching upper/lower). If I go with BCM uppper it would run me anywhere from $850-975 to get everything the YHM upper comes with. So anybody have any experience with YHM, any reason not to go that route? I understand that BCM is top notch with product and CC. Just trying to learn some more about YHM.
