    You’re using billet 7075? I don’t think I’ve seen those. Usually the bullet ones are 6061 and the 7075 are forgings.
    Yes, I understand that the lower doesn’t add or subtract from accuracy as it’s thought of. But accuracy is simply a byproduct of a culmination of high quality parts built to accent each other. Not to mention the loose nut behind the wheel(or trigger in this case) doing their part! I have no interest in building a quality, bullet proof upper and sticking a cheap piece of plastic under it! (Notice I said plastic, not polymer. If you need help understanding the meaning there, than you aren’t in the right conversation)

    Yes, 6061 was the norm when Billets were new on the scene....7, 8 years ago.. maybe longer. But now 80% 7075 Billets are plentiful among several manufacturers. I have put a tremendous amount of research into them, and have chosen the my supplier for several reasons.
    Nothing wrong with 6061 other than it being much softer, but like I said, I don’t go “lesser” on my builds in order to save $30 bucks.

    Before these 80%’s were available, I would ONLY use Spikes tactical stripped lowers. Believe it or not, I was actually one of Spikes Tactical's FIRST customers! I remember when they were a small start-up company, and many people thought I was crazy buying from them. LOL!

        Does anyone know what kinda durability or round count something like that can endure?
        I think the appeal is that some day you may not be able to get an Anderson, or ANY lower.

        I am a mechanical engineer, and I can tell you that if it is designed well (with enough meat around the through holes), it would definitely be strong enough. I would trust it way more than well designed polymer lowers.

          You do realize that AR parts that undergo far more stress are "screwed together"? e.g., carrier keys, barrel nuts.

            Yeah I’d absolutely trust it. I actually might look into one of these(in 80% form of course), as a lower for doing a 338 Lapua/50BMG upper. I think one ☝️ f these may fit the bill of a custom setup perfectly.

              Thanks for clarifying and enlightening me. I had no idea if it'd be strong enough.

                Your views on any given subject are the sum of the media that you take in, scaled to the weight of the credibility of the source that provides it, seen through a lens of your own values, goals, and achievements.

                    I'm surprised some company isn't cranking these out as complete knockdown kits.
