Blem M4 Lower
Picked up a blem lower on a whin and was very pleased with the quality. I had to search pretty hard to find anything to qualify the receiver as blem (small dent just above rear of grip location). Fit and finish is excellent
JMac m4 lower receivers
I have now purchased 3 of the JMac M4 lowers (1 alpha run, and 2 "blems" which were nearly perfect), and they are excellent quality and machining. Very high-quality finish. And they are low-shelf cut with the proper 3-position indicator markings. I will be buying more in the future. Very high-quality product. Highly recommend you give one a try.
