Is there a down side to quick change barrel systems being offered on custom actions?

Considering another custom build, and really like the concept of being able to easily replace barrels without sending to a smith. Having the ability to swap barrels from steel to carbon, 26” to 20”, changing barrel twist rate to accomodate a different projectile, it’s all pretty appealing. There’s several options out there, several manufacturers offering tight tolerances that allow pre-fits, there’s a newer outfit out of the Dakotas offering a quick change option, Carbon Six is pre-advertising a quick change action, the Gunwerks Nexus system looks great, and the Terminus Zeus quick change option.

The Terminus Zeus quick change really has my interest peaked. Is there a downside to these systems (set screws or other issues I may not be thinking of) vs traditional pairing of action and barrel? Durability, reliability, etc? Anybody have experience (good or bad) that they can share?

That’s a question I’ve been wondering about. Look forward to hearing responses

The Nexus has raised my interest in this too.

I have a Terminus QC Zeus. Waiting on a couple barrels but fully expect it to be like my other prefits. I don’t have to remove the stock, scope or put it in a vice. I will say the only downside is, nothing. Just kidding. Maybe the downside is a safe full of barrels and I couldn’t stop with only one action because who wants to change barrels all the time.

I can see this happening - at least we will be buying actions for proven barrels & loads!

I know the question was about US manufacturers but I hunted with several German hunters that had switch barrel rifles. Big difference is their rifles have the optics on the barrel so when they switched barrels their optics were already sighted and the lock up was extremely precise so I hey didn’t always shoot a sighter or need to. Most of those hunters had a heavier cal and optics for driven hunts (1-3x or aimpoint), and another smaller caliber for deer and small game with a variable power optic. They loved their rifles and I didn’t hear any complaints.
They typically don’t own many guns for a variety of reasons, and that’s why Drillings and over/under rifle/shotgun combo guns are readily available (308 and 7x65 over 20g, 16g or 12g)
I’m looking at a Zeus QC myself for a build I’d like to do in 300 wsm on a long action with a second barrel with a smaller caliber to be determined. Interested in the input from the group.

I have a Zeus quick change. Currently I have two cartridges being chambered in 25 PRC and 300 wsm. I will be able to report my findings in a few months after developing loads and changing barrels between the two.

I don’t think there is much of a downside. When I was deciding, the biggest negative feedback I received was once you have a rifle shooting good you won’t want to remove the barrel. I understand that logic, but what are you losing if that turns out to be the case for you? I don’t think the quick change option costs any difference, so you basically have a Zeus without the quick change.

The second most common was the barrel torque. It may make a difference, it may not, I can’t answer that yet.

Thanks for the info. I’m looking forward to hearing more about your experience. Like you, I do t see a downside, and the cost of the second barrel and maybe a bolt beat the cost of another rifle/scope: not saying that in a negative way because I’m all a out new guns - just look in my safe’s😊

Thanks for the replies. Would you have any concerns about using a rifle with the QC action on a back country hunt, either backpacking or on horseback?

Good question. I would Loctite the setscrews in the Terminus Zeus so, no for me.

Is a defiance and torqued pre fit any less repeatable than the zeus set screw option?
