Planning to run a mpa chassis and 6gt caliber with a 26" mtu barrel. The choices I am considering are a curtis axiom with switchlug, terminus zeus, impact precision, or lone peak fuzion. I like the idea of easily switchable barrels, and a 60 degree bolt throw, but dont want to compromise reliability, quality, or ruggedness. What would serve me best in prs

If you want 60° bolt throw and quick change features, then I would be more compelled to pick the Terminus over Curtis.

I personally have a stronger preference for 90° bolt throws and shouldered and torqued barrels, so I would personally take a Lone Peak Fuzion first, then an Impact over the other two.

But it's mostly subjective. What I prefer and what I think works best for me may not be to your preference/liking. Lots of top quality actions these days, so in most cases it's difficult to make a poor choice at this level.

I have no experience with Lone Peak, but for 90 degree it’s hard to beat Impact. No gimmicks, it just plain works day in and day out, and good customer service. If I were to buy a 60 degree I’d go Terminus Zeus without the quick change (full threaded tenon). Nothing wrong with Curtis, but I’ve heard some folks have had less than great experience with customer support. Just do your homework on that aspect of it.

What’s your budget?

A straight AI-AT works fine for PRS if you don’t mind the grip. MPA also sells a chassis for AI if you want to debond it.

Best quick change system on the market, 60deg boot, and feeds flawless with AW mags.

What he said ^^^

That being said, when it comes to actions, you might as well ask a woman what color/style of panties she likes to wear. Some days it depends on the clothes, other days it depends on the time of the month, and other days it's what ever is at the top of the panty drawer.

BLUF: It doesn't matter; pick what you like and run with what you brung...but AI's are still the overall winner (obvious bias on my part). :D

If the OP really wants 60° bolt throw, quick change barrels and AW mags, then I agree that this option really has no rivals.

I wanted to stay under 4k for the rifle not including the optic (7-35 atacr) so the ai all setup would put me outside of that. The price difference wouldnt be that big of a deal, but I already have money down at MPA... I have a call into them now to see what my options are as far as an action.

Do you guys prefer prefit barrels with a nut? Or shouldered barrels from a gunsmith
Shouldered for me.

Less parts in the system, more options for contours (specifically on the heavy end), reliable return to zero/POI when you take barrel on and off, etc.

It's a simpler system with less parts, that just flat out works. Barrel changes are stupid simple with a shouldered barrel as well, you just need the correct tools.

Personally, I see no reason to get a barrel nut system.

Do you have a gunsmith thread the barrels and put them on or do you have a custom action and you buy shouldered prefit barrels

I have a gunsmith that I use that has my thread specs on file. When I need a new barrel, I call him up and he spins one up for me. I get it in a couple of weeks and then install it at home.

I've personally have never bought an "on the shelf" pre-fit barrel.

I'll second this, honestly not one hiccup in 4000 rnds.
Glad to hear this, I spoke to mpa and the build is to far along to change anyway, so that makes it an easy choice. Mabey the next one will be an impact.

Huge vote for Defiance over a 60degree. I have a Vector and a Deviant. Would never dream of using the Vector in a match.

Something to consider: The bolt lift on my Vector is about 4 to 5 times heavier than my Deviant gauge verified. How do you expect to stay on target when by merely lifting the bolt knob will 100% take your crosshairs off target by a good distance?

60degree is cool and maybe not all 60's are as heavy as the Vector but I'd take a light bolt lift and longer throw over the opposite for a prs match when time, spotting shots and follow up shots are on the line.(y)

I've said it elsewhere and I'll say it again here.

60° actions are overrated for PRS use. People commonly argue that they are "faster" because you have 30° less bolt throw. Running a bolt faster does not make you shoot stages better. "Smooth is fast", as the saying goes. Running a bolt fast will only induce problems - like short stroking and double feeding, and moving your rifle off target.

That extra "speed", in 30° less bolt throw movement, also makes for a heavier bolt lift and close (for a 50/50 action) heavier. It's simple physics - you still have to do the same amount of work (compressing the firing spring) in less motion.

I personally much prefer a light bolt lift and close, combined with smooth bolt manipulation, to keep my rifle undisturbed as much as possible. Of course this is my opinion and my preference.

I don’t use a 60deg for the speed. I just prefer the feel. And they are easier to tune to AW mags.

I can stay on target no problem with my AI which is 9-12lbs and heavier than the curtis.

Withoit getting into the why they use them (sponsors and such) pynch, vibbert, Preston, etc etc etc seem to be fine with 60deg.

It’s one thing to have a preference for 90deg and that’s all fine and well. But if a 60deg is moving your crosshairs that much, it’s you, not the bolt lift. You don’t have the gun supported properly.

Also, you should be following through and not running bolt if you’re looking for the shot. Once you have your wind or call, run and gun. But the bolt throw should have zero to do with spotting shots.

I’m not a prs shooter but I do prefer a short bolt throw. Not for speed but for feel. I really like my Curtis Axiom, TRG, and the longest of the three my Tikkas.

Like I stated, it's merely a preference. If other people run 60° and have that as their preference, then that's cool.

I bring up the speed thing because manufacturers and even shooters on here bring it up all the time that it has the advantage of being faster, which I think is a poor way to shoot a stage, and is a big reason why people self induce issues. I don't think people should be looking to buy a 60° action because they think it'll make them shoot faster. It's another thing if it's merely a feel preference.

Yes, lots of top shooters are successfully with it. I never implied you couldn't be. Funny enough, the fastest stage shooters, like Matt Brousseau and Dave Preston, run their bolts slowly and methodically.

And yes, I follow through. I don't touch the bolt until I see where my impact was. But in a compromising position/barricade, it's nice to have the gun be disturbed as little as possible when operating the bolt, it's milliseconds but having your rifle damn near undisturbed and still on target when operating the bolt makes it quicker to make the follow up shot.

I have nothing against 60° actions, besides how they are commonly and disingeniously marketed as being "faster". My personal preference is a 90° with a light bolt lift and close, which my Mausingfield accomplishes beautifully.

Agreed anyone who thinks 60 is faster has never seen Phillip Velayo run a 90 degree lol and i am a proponent of 60 degree. I. E. huge tempest fan to this day my favorite action but it has to be run hard to avoid the hitch on closing. One advantage is honestly AW mags. There has yet to be a 2-lug that I’ve felt that feeds out of an AW like my tempest.

Right now I have an impact 737r and a tempest. My brother has an origin and i had dads gun built off an SR3.

I’m more than likely going defiance anTi for my 300PRC build because that price is ridiculous. There is no rhyme or reason over here for me. Other option would be a fusion but i don’t wanna venture into Ti prices.

Don't do the switchlug, youll regret it. Get a good barrel vice and action wrench and use shouldered barrels.
Can the barrel be torqued harder than hand toght with a switchlug? Would it help to torque it? Compared to a shouldered barrel would you expect to have less accuracy?

If you torque it, what is the point of the switch lug? 😆

If you’re still looking for actions I love my ultimatum deadline. Not sure how they play with MPA chassis though.
