Unfortunately cheap lowers are hit or miss with the hole for the buffer retainer. Operation on the mill for that tool path is important and a lot of cheaper lowers have the hole off enough to cause the buffer to beat the retainer up.With lowers you can always cheap out on them, so no reason to spend over $80 for one IMO. Same for upper receivers. What really matters is the handguard, barrel, BCG, and trigger (optional, but definitely an improvement). Depending on your budget, I recommend BCM or Daniel Defense for the first three and a Larue for a trigger.
Never had a problem with Aero Precision, but then that was my go to place when I lived in Washington.Unfortunately cheap lowers are hit or miss with the hole for the buffer retainer.

There’s other things about the lower that matter too and some companies will put out shit.

Which brands had that issue? Usually the worst I'd notice is play between the upper and lower but not a mismilled buffer retainerUnfortunately cheap lowers are hit or miss with the hole for the buffer retainer.

Anderson seemed to be the leader in that category. Core could be worse actually.Which brands had that issue? Usually the worst I'd notice is play between the upper and lower but not a mismilled buffer retainer
