I’m going to be in the market for a lower soon, but my local dealer’s 140$ RRA lowers just went to 190$ on obamma day. Seeing threads like this is making me feel less offended at that price every day.
well i had a peice of crap oly lower before so anything is an upgrade from that junk. both of my sun devil seem to be in spec so i will keep the two that i have in this market.
Yes. I had a second gen SD lower but sold it to obtain a Larue. I am much happier with the larue and it doesnt seem to ding and dent as easily as the SD did. Especially around the mag well opening.
Dont get me wrong. SD makes good lowers. But they are not worthy of billet prices. If you are going to spend extra money for a billet, get one made of more durable material.
The only true drawback I can see for 99% of AR owners when it comes to billet is pricing. I’m not arguing it is inherently better than forged in any category but appearance, but I’m also not going to chastise someone for throwing down 160 bucks on a Sun Devil in this purchasing environment. Sounds like a pretty good deal to me.
My SD uppers and lowers were around 140.00 shipped( around jan/feb 09). So, price was not an issue when comparing to standard forged receivers being close in price. At my local gun show, standard forged receivers were being marked between 150.00 and 250.00…now they are down to around 150.00 or so.
They are a good deal and a well built piece. It wouldnt suprise me if they last forever.
I would prefer a 7075 billet piece over anything else out there.
I have a bunch of Sun Devils Billet Lowers (Sun Devil even custom engraved one for me in case I decide to register this lower as an SBR)
This SD lower goes nicely with my billet LMT MRP Piston Upper
Not to hijack the thread but…
Has anybody used a Sundevil lower with a RRA .458 SOCOM upper?
I have one (complete A2 SD .458 SOCOM marked lower) on order and just looking to troubleshoot any known problems.
I don’t think there would be just checking…
As an actual Sun Devil owner, it seems a lot of bull pucky is being said by either people who don’t know or people that just want to put other brands down…As I have said in many other threads, I am new to the AR world, but I did do my homework before buying my receivers…The price of my Sun Devil SD15 lower was actually LESS than a DPMS, RRA, R-Guns, Stag Arms and many many more…the fit and finish is fantastic. My only complaint is the odd set screw, but it doesn’t really effect it much…if you don’t like it, back it out and use one of them red wedge thingies in. And to Jakal, my local gunsmith is currently making a Sun Devil/.458 SOCOM…odd
no… don’t ever do that. and your sun-devil does not have m4 ramps, BTW.
Where is this tensioning screw, I went to their web site and didnt see any pics?
I don’t have a Sun Devil upper. According to your reply in a different thread, I DO have M4 feedramps, at least when I looked is looked like I do…
The screw is at the rear of the receiver under the grip…it puts tension on the rear eyelet of the upper receiver.
i think it’s under the pistol grip. been a while since i fucked with one. it’s a little dhelrin-<sp?>esque set-screw that pushes up against the bottom of the upper when closed. as i said at some point in the history of this dead thread, all it does is make the upper hard to open and close- it still wobbles, plus it just holds the gap wide open.
ah. i cant speak for whatever upper you might have, then.
Guess it is one of those “well it looked good on paper” ideas.
So I should sell my 2 lowers and my upper since they suck.
In that case who wants to buy a used 80% complete SD lower…150 bux with the trigger group,selector, trigger guard,A2 grip and YHM pivot/takedown pins… Oh, it has been painted green by the Krylon fairy. 
The tensioning screw is right under the grip as stated above. It does make it harder to pull the rear takedown pin if you have the smaller standard pins or the KNS push button pins(I use these now). This is only if you tension it tight as fuck, which you shouldnt need to do anyway. I have it in the middle somewhere and I can pull the rear KNS pin even with gloves on.
I didnt have a problem tightening it more when I was running the YHM EZ-pull pins.
M4 ramps are not integral but they are easy to blend into the M4 extension with a dremel or hand file(I wish I still ahd the pics).
They are good enough… not the best and definatley not the worst.
I heard the horse gurgle so I thought I would kick it again.
Since this thread has been resurrected I will post in it.
I have several Sun Devil lowers and uppers and I like them. The lack of M-4 feed ramps is not a deal breaker for me. All my mags have anti-tilt followers and I have shot 77 gr ammo through them without an issue. Do I wish Sun Devil had M-4 feed ramps, yes. As someone else in another thread pointed out, there is no downside to having them, but again it is not a deal breaker for me.
Sun Devil upper receivers ARE now available with M4 feed ramps.
My SunDevil lower came in. It is marked “Model: AR458 Caliber: 458 SOCOM”.
The finish is really nice and the fit looks like it was a matched lower to the RRA 458 SOCOM upper. No slop, rattle or gap!
I put an A2 stock on it. I need to get out and shoot it since my .458 Barnes 300grn TTSX loads came in from SBR. I have the EO Tech 517 sighted in but that was with the 300grn Barnes TSX bullets, wouldn’t think that there would be much difference in the two, so POI shouldn’t really change alot.
I just need to get a Geissele SSA trigger for it and some sort of backup sights.
Clean and simple!
