I've built on a couple poly lowers, and then immediately sold them. That should tell you something. I do believe these are functional lowers that will generally perform admirably. I wouldn't build a rifle I intended to run 20K+ rounds through, or even one I deemed a personal 'keeper' around a poly lower. It screams 'cheap!'.
So because I typically build with quality parts (mostly BCM, some PSA), a poly lower will only do a disservice to my rifle's rep and resale value. In that regard, they'll probably never be for me. But it's not a bad idea to keep one around, if only to build an ultralight fun gun on one. Just don't go crazy trying to build a $1500 gun on plastic chassis.
