    Those of you 80 percent builders, what do you prefer in 7075 forged in 5.56 and 308?

    And to add..
    I've no issue researching them, just thought to ask the pistol pros their thoughts as well.

    I just got done finishing a couple hell fire armory 7075 billet lowers with their jig set. I have a CNC mill so the machining was easy once I got set up. 2 things I like about these lowers are the threaded pin hole(custom pin included) for the bolt catch and that they tap the hole for the rear take down detent. You can then retain the detent and spring with the included setscrew.

    I did have to alter their jig set some to do a 7075 forged lower(no idea of brand) I picked up somewhere but was able to do it as well.

    not much of a review but my $.02 :)
