Solus or Origin for first custom build?

Looking to build my first from scratch rifle, I’ve done a few barrel swaps on savage actions so between those two being compatible is nice. I’m just stuck between picking one. Anyone that’s handled both care to chime in and steer me either way?
 
Both would work fine but if you wanted to change caliber down the road the Origin is super easy to swap out the bolt face. Just something to think about if you wanted versatility out of the action.

As is the Solus (if you can find the bolt face you're looking for). However not sure if they have all the options as the Origin does currently (PPC face etc..)

Either action would likely serve you well. Most will recommend the Origin as there's concerns with Aero's financial status and support.

Exactly my point. Not even sure they are making a .223 for a Solus yet. Heard they were but haven’t checked. Also if he wanted a Grendel/ARC he is out of luck. Just something to think about for the OP when making his decision. If he doesn’t care about anything but .308 sized bolt face then it’s a push between the two as they both use the same shouldered prefits.

Agreed. Just clarifying in case he took it as the Solus can't change bolt face.
 
Solus… Both are nice, but I prefer the 60° 3-lug design of the Solus.

Bolt faces are just as easy to swap. Only issue is finding the bolt heads. If you google, you might could find one. The only one I’m waiting on right now is the ARC/PPC bolt head.

In theory, the Solus 'looks' better on paper - integral rail, recoil lug, "fat" bolt with 60 degree throw, trigger hanger, cut for AW mags.

None of which I've ever really found myself 'needing'. The rail and lug on the Origin are pinned, the 90 degree bolt is maybe a little lighter, and I've never subscribed to the notion of hot-swapping triggers on a field gun, personally. The AW mags are a nice option to have, though.

The Origin is controlled-round feed, with a fixed mechanical ejector, vs the dual plunger design of the Aero. Both have their pros and cons; all I'll say is that dual ejector on a bolt gun just seems... weird. Works, though, by all accounts.

That's about as even-handed as I can be regarding the two. The big difference is the customer support. Aero burned a lot of bridges over the past 12 months, you really can't piss in the well more than Aero did. The local Aero apologist (I'll let you figure out that one on your own) will tell you all about who/what/why, and why you should buy it anyway. On the other hand, if you need support from Zermatt, you can typically get ahold of a *person* in pretty short order. The owner (Ray) frequents the forum here, and is responsive as well. Aero? Good fucking luck.
 
Do you prefer:

Solus - integrated recoil lug and rail, lower 60 degree bolt lift, 3 lug action feeds from AW magazines, trigger hanger may or may not require a little relief cut in your stock/chassis (not a big deal), fit/finish/feel more like a higher end production gun action, questionable customer service

Origin - pinned recoil lug and rail, 90 degree bolt lift, does not work with AW magazines, no trigger hanger, fit/finish/feel of a custom action, top notch customer service.

Both use the same prefit barrels. Both can be used to build a good precision rifle. I own both. Unless you buy the Solus on a crazy sale, the Origin is the way to go.

I have a couple Origins and a Solus. The Origin overall is a better action but the Solus isnt far behind in my opinion.

The Solus has some really nice features that are hard to not like....trigger hanger, integral rail, dual ejectors, 60° bolt. Savage/origin barrels.

Buy both.

I’ve had a 223 solus bolt head for 4 months now and I’m definitely not a preferred customer.

I have no complaints with the Solus but the I only reason I have one is because the price and availability was right at the time.

If price is anywhere close, I’d go Origin b/c they have spare parts and responsive customer service. Aero has neither currently.

Trigger hanger is preferred? I would never buy an action that had one. Whenever you see people having trigger issues always seems to be a trigger hanger action a majority of the times.

To be honest for me, I don’t mind to much about if the rail and lug is intergraded or not, I don’t mind to much about the angle of bolt lift, I just want it to be smooth. And running the bolt I want to be slick and not bind. I guess all in all, I’m just looking for an action that’s smoother than a savage but with that same barrel system, and the aftermarket support of the 700 footprints. So I guess my main concern would be the overall fit/feel of a custom action.
 
Origin. The controlled round feed and receiver mounted ejector contribute to the reliability Zermatt is known for and gives the action a nice feel running it slow or fast.
Both have tool-less removal of the firing pin assembly; which I prefer in a field rifle.

Ok.

I haven't had an issue with a trigger that could be tied to a hanger. But only have a couple actions with them. So I guess I don't have enough experience to have an opinion on weather they are preferred (which I didn't actually say)

I put a Bix n Andy in my Solus when I first got it, and it didn't work properly so I assumed it was the hanger interface. I tried the same trigger in a couple of my Rem 700s and one of my Origins and it did the same thing, fire when the safety was pushed forward. I sent it back, allegedly it was rebuild, tested and sent back to me. It did exactly the same thing on multiple actions again. It's in a ziplock bag on my bench as a reminder to buy trigger techs.
 
Origin > Solus.

Most of the same things I'd say have already been covered.

But just remember that buying a Solus means buying an action from a company who's bread and butter is really selling zillions of entry price-point AR thingys, and they already have a piss poor reputation there, so it's no surprise that they're suspect with supporting the Solus stuff too.

Buying an Origin means you're buying a Zermatt/Big Horn, a company with a great reputation and who only really makes solid bolt-gun stuff, and with that, you get some of the best customer service in the game if ever needed.

I've said it before and probably will say it again, but I bought an Origin as my first "custom action" figuring I'd upgrade to something pricier once I came across something that was a noticeable upgrade. ~4 years and 7-8 barrels later, after having tried just about every other action out there, I'm still running my Origin, and don't feel like I'm giving up anything to any of the other actions out there at all.
 
Soon we are having a great range to shoot again. I hope to see you there this winter?

Depends on if his OF account finally takes off. So far, I think he only has two subscribers and one of those is a mod here...

Origins run really well. I wouldn't hesitate to buy another.
 
The obvious and only correct answer, according to Hide standard wisdom, is BUY BOTH!!

All kidding aside, I have both. I started with the Origin and then bought a Solus on sale before they hired that idiot to manage their operation. I bought it because of the 60 deg throw and the fact it uses the same prefits as my Origin. That said, I would recommend for your first custom action that you buy the Origin over the Solus. The Origin is a nicer feeling action, the customer support is worlds better, and the resale, if you ever want to sell it, is solid. Good luck getting parts for anything Aero makes, I’m still waiting for them to release the folding adapter to their chassis and they announced it as a product in 2023.

Go Origin and never look back. If you want to build a lightweight mountain hunting rifle, look at the MacBrothers Element, it weights 19.8 oz.

You said “hard not to like” so I thought it was preferred as I prefer things that are hard not to like. lol You can have any opinion you want on the subject as I was just giving mine that hangers are not needed and are very easy not to like. 😉
