I have to add a bit to this. I have 2 ASA lowers and 2 Bushy lowers and 1 RRA Lower
my ASAs are excellent lowers as are the bushys but th RRA is a bit of a quandry the outward appearance looks fine but the rear area of the top route where the rear lug of the upper goes is out of spec as the upper will not pivot into position, the upper is NOT the problem it works fine on every other lower I own, the RRA is the only one that exhibits this issue, you ca position everything in place as long as you don't have the pivot pin in place but then you can't get the pivot pin and the takedown pin in place at the same time, as for the purple comments well NONE of the ASA receivers that have passed through my hands are purple and there were a few, also none of the bushmasters I have been in contact with have been purple either the only purple lowers I have encountered were Sendra and an OLY (Different shades and the oly finish was the darkest the finish was slick not flat and nearly black with a slight Bluish purple look) I don't have a pic that captures the look but it was a dead ringer for the finish on those Cobray flare launchers.
