Which action has highest barrel availability?

stello1001 · 2025-09-14T18:01:56-0400

Hey all,

Been thinking about it for a while now. Maybe I should upgrade and get a better rifle. I have many, but the one I'm thinking about replacing is my howa in 6.5 CM. It's a prs style rifle and has served me well but every now and then, I get that itch about trying something better.

My 3 top contenders, in no order, are a t3x, a seekins hit, or an origin/nucleus.

I've heard seekins makes a very fine rifle and has some of the best customer service. I also really really like the rifle as it looks.

Tikka would certainly be an upgrade from my howa I believe. While shitty customer service, you can sometimes snag really good deals here so it might be worth it if there is really good deal to be had.

Origin or nucleus are absolute certain upgrades. Not really looking to spend on the higher end customs but these seem like good options.

All in all, I would prefer an action that barrels are easy to find for it. I'm not sure where that leaves the seekins, or what type of barrels it takes. I've seen many barrels for tikkas here on the PX so that tells me they're pretty common for the tikka. I've even found some pretty good deals that I've almost bought a barrel before just in case I ever got a tikka. Origin and Nucleus seem to be popular actions but I'm unaware of how easy it is source barrels for those. I think I've seen more aftermarket barrels for tikka here than for these two customs. Any thoughts?

It's hard to beat the Origin for value vs quality. I have a couple and they are great. If you get the lug from Hunt's Long Range, you can run the TL3 barrels as well. REM 700 pattern makes it easy to find triggers, stock, and chassis. Of these options, the Origin is an easy win for me.

I would look at Impact

This. Super action, smooth as silk, super barrel availability.

Impact precision

I'm a huge zermatt fan. Go origin unless you want a configuration that's only available in tl3.

You want an impact 737r. It will have the best barrel availability of any short action on the market. Period. End of discussion.

Origin.
Arc doesn’t make a nucleus anymore, they are all in on the cdg going forward.

But if you like your pre64 win70s, you’ll like the controlled round feed and mechanical ejection on the origin.

Yep. You got a gen2 Nuke you wanna sell?? Haha I absolutely love mine. Been eyeballing the CdG since I've gotten to shoot a bunch of them. I just don't wanna have to buy a buttload of AW mags....

Out of those options, the Origin.

There are plenty of prefits available for many actions these days. Which action has the "most" shouldn't even be a criteria, IMO. You really just need to get to the point of enough, where its easy to get a prefit. Of which there are many actions that fit that criteria.

Another point for zermatt is that changing bolt face dimensions is both tool free and comparatively cheap. Under 150 shipped for bolt heads vs 350 or more for a new bolt in most brands. Makes having a 223 trainer barrel really easy and even more economical.

This was my train of thought. I said nucleus on my OP but I was actually thinking CDG. Thanks for bringing that up.

Today I shot one of my SPRs and boy does that thing just bring so much joy. I like the CRF. I'm looking up the 737r per the recommendations here but those do not appear to be CRF. I'm not dead set on CRF but I'll probably lean that way a bit more than push feed.

I was just shooting a fri3nds 737 in a foundation this afternoon while testing some 77gr loads in my PWS mk114. The 737 is a slick action (most in that price range are, TBH). I'd put it above most stillers that haven't been worked over and on par with one of my defiance deviants.

I'm kicking around adding a 737 or nbk to my safe but honestly the CdG is just as slick. Thr origin (a cheaper version of the tl3s I have) is hard to beat, though. I've put more than a few together for guys and nobody has griped.yet. zermatt is great to deal with and their CRF/ME actions work regardless of case length. Since I like my 6br based stuff, that's a thing for me. My friend is running his CdG in 6arc and it's perfectly reliable.
