Had the 3 packs for around $30 a piece awhile back ?

Tactical Machining has them for $29 if you purchase 3 in the white. There are other specials they have right now too and also engraved lowers have been added.

I've bought several TM lowers before and they were in spec.

Thanks

I have bought several TM anodized lowers and they are excellent. (several uppers from them as well, and they work fine)
I do wish that TM would put Fire/Safe markings on their anodized lowers.
On several I just drilled a peck mark and filled it with colored paint (red for fire, white for safe)
And on several others I had them laser engraved, which turns out really great. The laser eats through
the anodizing and exposes the bare aluminum beneath. It looks fine.

I use Graphic Electronics in Spring Valley, IL. They are great people.

Same way I've been doing mine for years. Clean and simple.

If you drill out an 80% that is anodized, doesn't it expose the aluminum that is underneath? Wouldn't you have to have it anodized again to cover those spots?

only if you want to... just keep it clean and oiled and it will be fine without it.

None of the raw aluminum is visible once the rifle is assembled. Obviously rust is not an issue, but, a  light film of oil will keep it looking good.

Me too.  Clean, simple, and no engraving required.
