Blems....
I don't think so not when you can by a quality lower for about a hundred bucks..
Or less; I got my Spikes lower not too long ago for $89.00, IIRC.
Once upon a time, I bought a "cosmetic blemish" lower from a known mfr. at a gun show for about $60. Turns out, the blemishes were more than just cosmetic. I'll pass on these.
