    But yet you refuse to address the situation about your lower receivers.

    Agreed?? Just skipped right over that.
    Was there a previous problem, that has now been fixed? Were previous customers taken care of in a fair manner?
    How's your QC now?
    Looking forward to responses.

    Thank you for an opportunity to address this issue.

    First, there is no "rise" in the mag well. There is a process line where the broach comes down from the top and then up from the bottom.

    We made the mag well slighty larger than the standard print dimensions to allow for Lancer and Pmags, which are plastic and prone to minor swelling. So, in fact the mag well on the rifle in question is larger and should have no drag on a P mag or any other mag.

    We never said that we were not going to fix the issue until the next production run. What we said was that the first run had this line on it that did not effect function of the rifle. There is no way that this line damaged a P mag.

    From there where does it go?

    Doesn't it just drop into the action...possibly onto the now-exposed tail of the bolt or the locking lugs...since there is no structure in-place to 'kick' the pile out of the e-port as the forward edge of the 'wipe' slides clear?

    How is this 'better' than the swill just riding the BCG somewhere in-between the 'rails' and staying off of the bolt?

    This is the issue I see, as well. Unless his plastic is more like "rubber" and is acting as a sort of squeegee on the upper receiver (which seems like it would cause all sorts of funky issues with the drag) then all you've really done is tightened the tolerances. Debris can still get in, albeit in smaller amounts, but that debris that does get in is going to be in contact with multiple surfaces instead of just riding around harmlessly.

    I agree that was does get scraped off seems like it would just fall onto the bolt and/or exposed magazine.


    I like the gas regulator idea, I think that's way cool. Wish you offered it as a retrofit in an M4 style front sight. The other ideas... Eh, looks like a "solution" that's trying to cause a problem.

    There is no problem with the mag well. What you have is a process line, not a "step" or "rise". You have one example of a customer who did not like the explaination he was given. There is no problems with QC. We did eliminate this line on new production lowers but again it did not effect the functioning of the rifle becuase it is slightly over sized to allow for plastic mags.

    Please remember that Adcor is a small and growing company working its tail off to establish itself in the industry. Should we have done a better job on follow through? Yes, but there was no pleasing this customer from what I am told.

    You've explained it well enough for me... Thank you.

    I don't get it, you say the line(ridge, edge, whatever it is) didn't cause any problems, yet you fixed the issue. So I guess I have to just say nothing more.

    As far as the forward charging handle eating into the receiver, I think that it must be normal for this design or it is a problem they all have. I was looking at an SBR upper at a local shop and it had the same exact gouging in the same location as the OP's gun.

    Yes, very simply, since the line was an "issue" for some and obviously not cosmetically perfect, we made changes to eliminate it. Again, it had no issue on the functionality of the rifle.

    Please understand that this was our first attempt at making lowers.
