For those of you needing a lower receiver:
Whoa, they also have the LMT Standard Service model:

Unfortunately, I am in no position to pull the trigger on one. But maybe some of you guys can do it.
I can’t warm up to those SunDevils. They have some receiver tensioning screw in the bottom of them… plus they’re billets.
just back the receiver tensioner all the way off if you don’t need it, and what is wrong with billet??
i don’t like billets either, i’d just rather have a forged lower. the “tighter tolerance” thing is a marketing gimmick…and tighter tolerances aren’t always a good thing.
the only time i ever had a problem fitting a LPK was on an out of spec $300 billet, so it sort of spoiled the appeal for me. i know this is statisticly insignificant and meaningless…but personally it ruined whatever allure was there w/billet lowers.
plus the sun devils are 6061 right? eh. the plastic or nylon set screw just seems like a bad idea to me. not sure why you’d even want it.
Nothing wrong with billet lower. Die hard forgers will poo poo them, not as strong, etc… Get billet lowers, if you like them. As long as they are in specs, you will be fine.
An engineer on another site layed out the facts on Billet vs. Forged. There is no factual basis for claiming that billet is as strong as forge. Does it matter? I don’t know. Maybe not for most shooters.
As far as the gay screw thing… forget it. I’d back it all the way out. But then you’d end up with a big hole in the bottom of the lower. It just doesn’t belong there.
It’s also Olympic Arms claim to fame. Enough said there.
Sun Devil uses 6061 aluminum. Too soft for a receiver. They get away with it by making it from billet. So while it it nice to look at, cosmetics are all you get as a bonus from Sun Devil’s billets.
Get off your high horses ragging on billet lowers. Forged receivers have certain good points and billets have their own superior features.
If you are cheap and can’t afford the better finish and look of the billet…then so be it…but don’t run them down just because YOU choose to not like them!
It appears to me that there are a Hell of alot of people who like the billet receivers considering the wild success of the LaRue Stealth series and the HIGHLY praised Magpul lowers that are selling like hotcakes as they are built up into guns by Noveske!
funny stuff
you’re joking, right?
I hope he’s joking.
The Sun Devils don’t run any more than a forged here anyway with the market for lowers between 150 and 200 dollars.
All gone. 
I was not speaking specifically about Sun Devil lowers in my earlier posts. I was thinking more about…

LaRue Stealth

Magpul

I have a Sun Devil lower and it is great, in spec and works just fine. It has held up just as good as my LMT. I have it mated up with a Sun Devil upper and it is a better fit than my Colt M4.
In my book Sun Devil products are good to go.
Note: The uppers do not have M4 feed ramps. Which is fine if you are building a SPR or just a precession rifle.
i already have a POF Gen II lower.
i honestly prefer my forged lowers…and it has nothing to do with being cheap. with the money most of us put into our ARs, a couple hundred here or there doesn’t mean too much.
different strokes for different blokes, i guess.
Those billet receivers are made from 7075 aluminum. They are worth buying. They look good AND are actually stronger. Again, Sun Devil is just for looks.
I’m not a machinest, but my gun dealer is. He builds suppressors and all manner of AR accessories. This is what he says about the 6061/7076 debate:
6061 aluminum has some significant advantages over 7076. While 7076 is “harder” than 6061, it is more brittle. 6061 has a lot more “give” and resilience. 6061 is also more corrosion resistant.
So once again, there is no free lunch. 7076 (particularly 7076-T6) has its advantages, but it is not inherently superior to 6061.
Just curious, do you have actual experience comparing Sun Devil lower head-to-head with your favorite forged lower, to make your claim?
i’m not all that happy with my sun-devils… can only use DPMS charging handles (don’t ask me- that’s what they say and that’s what i’ve experienced), very loose fit between upper and lower- and the tensioning screw just makes it hard to pop it open, it still wobbles even tightened up so tight you can’t take them down without a hammer and punch- and the worst part, the rails aren’t true m1913, so it’s weaver-only for mounting without modification to the item.
they look great, though.
