correct, although the picture i posted with my 512 on it has not been modifiedThanks Charles ...if I get this right, I need to let my dealer know to contact you for the uppers that have the sides lowered so I can use my 552 on it (I have a 552 not a 512 - does that make any difference?)
Yes, but you will need the barrel clamp and the railed adpaterand then wait for the new barrel clamp so I can have my front sight co witness with the 552.
150 pieces will be complete tomorrow and shipping to dealers. That issue has been sorted for this batch. From what i understand, none of the dealers have stock right now on uppers or lowers. So any new orders will be filled with an upper that has a captive ball.Will the modified upper have the captive detent ball of the 4th generation uppers? (I've had a standing order at my dealer for a set of uppers and lowers for a while now but have been waiting till it gets all sorted out).
I'm assuming that the lower hand guard will be fine as is with the modified upper - correct?
