Looks like they were on the right track then pulled off a huge fail with that trigger guard design.

I dig the looks of this, wouldn't mind having one and a matching upper.
Because I need another receiver set and all...
Would consider swapping for my umbrella set on my current set up. Hell its being reworked anyways.-One Nation, Under God

Okay so the obvious question is why?
Why is this more expensive than Noveske Stihl cryptonite?
Why NOT Titanium? They make everything else in Ti.There's no "Team" in F**K YOU!

Because Titanium is heavier, heavier than aluminum, and definitely heavier than Aluminum Lithium.
As for price, I never machine Aluminum Lithium so I'm not sure how easy or hard it is (tooling/machine time/whatever), but pretty sure it's not a cheap alloy. I read about it being used in fighter aircraft several years ago, kinda wondered when or if it'd hit the AR market.-One Nation, Under God

But 7075 AL-Li isn't aerospace alloy, really, and it has its own flaws that Ti doesn't have. Sure, a firearm won't exploit those weaknesses, but Neither will plain old 7075 AL. So, it better be a hell of a lot lighter, because they took away the whole exclusivity thing by including that horrid trigger guard. It doesn't fit the design any better than a snorkel hoodscoop fits on an Enzo.

7075 Al-Li isn't a thing, either.
(however, 7075 WAS(when in vented)/IS(currently in use) Aerospace, as well... fun fact )
2055 and 2099 Al-Li is a thing, and both ARE Aerospace alloys, being currently used by Boeing because they reduce maintenance cycles, have enhanced corrosion resistance, decreased crack propagation propensities, and higher modulus of elasticity. They also weigh a few percent less. *all as compared to 7075
The only "flaw" with AlLi is how painstakingly careful the anodizer has to be to get Type III RIGHT, and increased tooling wear and different CNC programs to account for thermal and shift differences in the material when cutting. It literally trumps 7075 T651 in every aspect from strength to weight to rigidity to resistance to fatigue to corrosion resistance. There is NOTHING it does not do better.
But...7075 will also do the job of "M4 lower". I won't argue that in the least. That said, so will 6061. Would you like a 6061 lower for the same % less as Al-Li costs more, than 7075? Why or why not?
OP, did you double-check the ACTUAL weight on that lower acclaimed at 6.4oz? I am not at all saying Joel is not 100% accurate, I would just like a 3rd party verification.Last edited by JGifford; 21 December 2016 at 23:05.

At that price I would expect ambi controls.

I actually think the price is good for what it is.
Titanium is 3x the cost: http://www.vertexops.com/mobile/prod...-ti-lower.htm=
