As the title says, any comments about them, good, bad, or otherwise?

Good to go. Have had a few.

I purchased 2 and they were fine...not real expensive either.

The only thing I think I've heard is that you can't use one of those buffers that some people use. The accu wedge. The shelf inside is too high.

Yes, they have a high shelf, PSA lowers as stated above are GTG.  Blemished lowers on sale are GTG also.  Your would be hard pressed to find it on most.

I'm running an AccuWedge on my PSA build. The AccuWedge can be trimmed.

Thanks to all. Seems like it will work out fine.

The new Midwest lower has a jacking bolt so there is no need for the wedge. For $99 it cant be beat. The bolt realease takes a set screw too so no need to beat the roll pin in and out.

Well yeah, that was obviously my first thought but I don't want to screw with the integrity of the wedge because I don't want it to come apart and jam something up. I've heard it happening without it being trimmed so trimming it will just exasperate the problem.

You guys should try running an O-ring over the front pivot pin lug...tightens up everything nicely...no need for accuwedge and worries about trimming and jamming..got like 10 of em at lowes for a couple of bucks
