Terminus Actions

[glock24]

Now that some time has passed and these actions are a bit more mainstream, I'm curious to know if there are any scope mounting options for the Terminus bolt pattern that utilize the one-piece ring and base combo that Talley kinda made famous? I know Hawkins Precision and Leupold also have their variants now too.

Any variants that fit Terminus actions? Specifically the SA Apollo (if that matters)

Cheers

Are there any other bolt knob options for the Zeus aside from what Terminus sells?

Threaded 5/16-24. Terminus knob is male threaded, most aftermarket are female threaded. Just connect using a 5/16-24 set screw. Google bolt knobs, dozens to choose from.

 

[hairy_pineapple588]

Is Altus the best bet to get one?

That’s where I got mine. Ordered on a Tuesday. Picked up from ffl that Friday.

 

[hairy_pineapple588]

What trigger are people using in their Terminus actions?

 

[Hattrick]

TT Special

 

[hairy_pineapple588]

TT Special

It’s my understanding the difference between this and the diamond is just the trigger weight. Being the diamond is adjustable to 4oz and the special is limited to 8oz?

 

[Hattrick]

Yes something like that. The special I get plenty light enough for me I run them on 2 different rigs super crisp

It's probably mentioned somewhere in this mega thread, but is there any negative impact to the performance or setup to get a QC Action and thread on a full threaded/non-QC barrel?

I know the set screws would need to be removed, but other than that, would there be any issues?

What’s the advantage of the full thread on a quick change action?

No no impact.

There’s no advantage. It’s just you don’t need to have a quick change barrel to use the quick change action. The full thread barrels work too except they will need to be torqued properly because a demotion the set screws aren’t used.

 

[LuvDog]

What’s the advantage of the full thread on a quick change action?

The only advantage is that I could pick up a used or barrel that is full thread.

I would contact Joel.

 

[Ty21]

If you have the qc action you can still use the full thread barrel you just torque it down instead of using the set screws

 

[Dolomite]

look at the tenon print on the website. I think it mentioned about .002 head space difference between QC and torqued barrels. Depends who chambers the barrel may or may not make a difference.

 

[Screach]

Anyone know of any long-term detriments to frequently swapping barrels on the QC action?

I currently run 4 different caliber barrels on my QC action for various tasks, and I have been concerned that the high frequency of barrel swaps may cause issues in the long run. Anyone know of issues that may arise with the action threads from these changes? I am careful to follow all protocols on proper barrel replacement each time.

Along the same line, is there an issue with routine removal and replacement of the action screws to move the action from a competition chassis back to a fiberglass stock? I am careful to make sure no cross threading occurs and I use proper torque values each time.

I am not an engineer so I don’t know if this is a legitimate concern or if I’m completely off base.

As long as you don’t destroy the threads in the process, it should be fine

You deserve another Terminus Zeus QC action. Just do it!

What do you mean by high frequency and routine removal? Weekly changing out barrels?

 

[Screach]

What do you mean by high frequency and routine removal? Weekly changing out barrels?

I may swap barrels a couple times on a range trip to test different loads. Then for storage I keep the action separate from the barrels in my case due to size restrictions.

Stock wise, I may swap stocks once or twice a month.

@Milf Dots Lol. I thought about it as I was writing out my post. But I’d have to buy a LA first then I’d be out $3k

 

[Hennig]

Well this certainly jammed up my action mid shoot today.

Is that the roller on the cocking piece?

 

[Hennig]

Is that the roller on the cocking piece?

Yep, pin is gone, roller jammed between the shroud and cocking ramp (I’m guessing), and wouldn’t let me unlock the bolt. Look. Lot of shaking and wriggling and eventually the roller plopped onto my lap and the bolt was functional action. I guess I should email about a replacement pin.

 

[Tokay444]

Roller doesn’t look round and neither does the hole.

 

[BuildingConceptsllc]

Yeah it really doesn't. It looks out of round as does the pin hole.

If he says what caused it or how to prevent it can you post about it please?

Maybe that’s why it fell out.

Break the rules again and you will be banned. The PX is the place for this and you need to be a supporter.

Hey, as an update on my previous question about wearing out the threads, Joel gave a response this morning:


“As long as you lubricate the threads with any type of grease, you will never wear out the threads on the receiver or barrel. The receiver has a Rockwell hardness of 42, and a DLC treatment over the steel which boosts the surface RC a few points.

Joel”

I have greased the extensions with: 'Loctite 234227 LOC51048 Moly Paste Anti-Seize Compound'. I use area 419 chamber protectors to keep them clean. No affiliation with area 419.

Chamber and Thread Protector

As it becomes more popular to have multiple barrels and bolts for rifles, we are seeing an alarming number of barrels stored with nothing to protect the chamber or chamber threads. Well, that ends today. The Area 419 Chamber and Thread Protector is milled from 6061T aluminum and simple screws on...

Just ordered a long action zeus from front range precision to build a 300 norma. Can't wait to get this thing in and check it out. Joel is still super responsive with his customer service. Think he emailed me back in 30 minutes when i had a question.

 

[Hennig]

As a follow up to my roller cam issue - I finally remembered to email Joel, had a response within the hour, and new parts on the way a few hours later.

Awesome

 

[hairy_pineapple588]

Anyone shooting 6 dasher or 6 gt on a Zeus? What mags are you using?

 

[Csafisher]

6GT with arc mags. No issues

 

[louu]

Anyone shooting 6 dasher or 6 gt on a Zeus? What mags are you using?

Dasher with the mdt metal br mags. I put the extensions on them, tuned the lips, deburred and polished the lips. The berger 105 hybrids are a little shitty to feed, ya gotta run the bolt hard. The Hornady 108 eld match bullets feed like butter

 

[Bravo6niner]

The new mags from gray ops run awesome!!

Are you running 6BR or 6 Dasher?

Thanks.

 

[Bravo6niner]

Thanks.

Dasher

They run 6br in my sons cdg flawlessly too

 

[inertia]

Anyone seen or tried the terminus mags listed on the site?

I'm also curious about reviews on the Terminus bottom metal if anyone's run that.

 

[Mj1995]

Just ordered a krieger 30" barrel for my terminus for a 300 norma. This action is sweet. Anyone on the fence about getting one should definitely go for it.

 

[FimRire RongLifle]

I just ordered another SA zues didnt want to get just another bolt. Loving QC but the more rifles syndrome strikes again!

 

[shlouf]

Did anyone get one of the gold Zeus?

 

[hairy_pineapple588]

I just ordered another SA zues didnt want to get just another bolt. Loving QC but the more rifles syndrome strikes again!

I’m in this decision currently. Have enough saved for another action. I’m highly considering another Zeus QC but the allure of an impact is there. What made you decide on a second Zeus?

 

[hairy_pineapple588]

Anyone running multiple Zeus actions? What was your deciding factor in having more than 1? I have a Zeus Qc and am in the market for a second action but nothing looks quite as appealing as a second Zeus.

 

[Hennig]

Impact is the only custom action I’ve sold within 6mo of buying it.

If you want a 2lug, get a Fuzion.

 

[FimRire RongLifle]

I have one qc and two bolts. I picked up another action with a 3rd bolt face instead of buying a 3rd bolt. Motivation was to be able to keep two calibers online.
I'd rather stick to one platform now barrels can swap bolts etc.
