There have been some stupid low prices on lowers lately. I'm still leaning towards the polymer lowers because I'm pretty handy with a dremel. I have ni interest in .223 so If the polymer lowers can stand up to 9mm and maybe 7.62x39 then I can see having a couple of them to build on at a later date. I'm sure sure the metal lowers are better quality but I'm not trying to build any teotwawki rifles. I also cant really see putting any money into jigs and milling equipment.

The poly lowers I have had and look at all state they are fine up to 7.62x51/308.

The $35 ones are blems, a lot of people say they are out of spec so you will most likely need a jig to finish the holes. A few people have also gotten ones where the takedown pin holes were a little off (warranty covers that, but being polymer you can fix that with jb weld and a drill

I don't think this was for the blems. if i recall right it put regular priced items jn the cart but i put in a coupon code that knocked the price down. I could be wrong but I'm petty sure especially seeing how the inventory went to zero so fast.
