    Well, it looks like we have the same magwell dimensions. The 2.957 vs 2.953 in length is within .004 and our widths matched dead nuts. However your mag dims are a little smaller than mine. But even going by your measurements the magwell is only about .030 larger than the mag.

    yeah thats what i math'd out... about 30K....

    but does yours rattle around like that?

    since our magwell numbers match, that means the lower is fine & another member checked another brand & was also within a K of both of our numbers....

    so that would mean its the mags. guess i'll grab 1 expensive metal mag & see if it makes all that clatter.

    wonder if maybe its the mag catch? thats the only other part that has any contact in there.

    Sorry to be ignorant here. Does Stoner or ASC mags differ in their dimension or lockup? I really don't know. Another reason I've avoided the AR10 all these years.
    We all know how to change mag fitting on an individual basis.
    If the mag locks and feeds?

    gonna get a different brand of mag when im at the creek...

    but gonna swap mag releases tonite & see if that makes any difference.

    did it feed? yup functions fine... but would you wanna carry it around with that rattle? it looks soooo cool & mod... cant have a ford sounding rattle in it.

    ok.. did a couple things & got the rattle of the mags out.

    1. different mag catch (couldnt "see" anything wrong with the other one)... that helped

    2. different magazine. fits way tighter than these magpuls did.

    now we move on to the upper & some things there..

    found out that the BHO wasnt working all the time. turns out that this was a clearance issue in the upper. the BHO lever was hitting the side of the receiver & stopping before it could get high enough to cath the bolt. easy 30 second fix to get that clearance & problem solved!

    thats all for now.

    update time!

    problem solved!

    thanks to the member who said "go with the ASC mags" & provided a good link to them on sale!

    they came in today, went out loaded 10 in each mag (5 romy, 5 SAF) staggered..

    dumped them ALL. no hang ups, no failures of any type.

    will try again with another brand of lower on this upper over the weekend.

    but it seems to me at first glance that this AR10 just doesnt like the MagPul gen 3 mags. im shocked & baffled as ive never had a MagPul product not be just top of the line. ???

    but in this gun, in this set up? they just dont work.

    thanks to all who advised & made suggestions!
