Good deal on these DSA blems. DSA ZM4 Stripped Lower Receiver - DSZM4R-D S Arms My DSA upper is top quality, I assume the blems are just cosmetic.
I bought a CMMG lower for $125 about 18 months ago... Wish I had waited :^) DSA has a great name - especially with the FAL community. I might try getting one of their AR uppers pretty soon. They also have a 6-pos collapsible stock for $50.
thats my upper, 0 defects. Good fit with my Kaiser lower and Bravo Company BCG. I believe DSA also makes the buffer tubes for Magpul and another big name I can't recall at the moment. Initially DSA had QC issues w/ M4 feedramps but mine are perfect.
