Post a pic. With a file or grinder if you know what your doing u can easily fix it.
Action: Zermatt Origin LA
Trigger: TriggerTech Primary
Stock: Greyboe Terrain
Bottom Metal: A mix of RedHawk & Remington BDL parts with a Wyatt box
Barrel: Preferred Barrel Blanks 24" 280AI - shouldered
Future Barrel: Criterion 19" 270 Win, threaded, fluted, cerakoted black, barrel nut to save weight. Should arrive in a few months.
Suppressor: Harvester Evo (in ATF jail)
Scope: Meopta Optika6 2.5-15x44 BDC 30mm SFP
Front Action Screw: Bubba'd
Weight Unloaded with Scope: 10.2lbs.
RedHawk Comment: I shot them a note last night after 10pm that the threads on my Front Action Screw were a mess. By 7am Central, they responded that they would send me a replacement.
Obviously, this rig is not svelte set up this way. This is my I don't have to walk far setup. I will probably have the 280 AI barrel cut back to 21" and threaded at some point.
- When the 270 barrel is on the action, it will get a lighter scope and end up in the low 8lb range.

Planning my first build with an Origin LA for a 7 Rem Mag and having a bit of hard time validating what bottom metal options to run. Any recommendations on bottom metal setup all in for around $200-250?
My plans as of now —>
Trigger: Trigger Tech Special
Barrel: Proof Carbon 24”, 1:8.4
Stock: Mesa precision altitude
Bottom metal & AICS mag: Mesa precision and mag (TBD) or standard BDL kit

I went with BDL because I was confused by all the inletting talk + I didn't want any rattling steel mags making noise.
Honestly, if I could have figured out a way to have a flush fit DBM without spending a fortune, I would have gone that route.
My rifle is 100% hunting. Guys shooting matches will probably want the ability to load larger magazines.
Thank you sir, the first one works for me the best, he had it put together wrong he had the washer in between the baffle and the head. Which way does the baffle go? Mine has a taper on one side and flat on other?
It is very hard to find a good video on how to reassemble the bolt assembly and put it back into the action. I tried all kinds of search terms and could not find a detailed video on bolt disassembly. Most of the videos showed how easy it was to take it apart and said just do it in the reverse.
I have been told you can reinstall the bolt in the field without tools, but getting my bolt assembly back on the action was very difficult. I did it, but I couldn't do it in the field.
It's literally the same steps but backwards. And yes it's just at easy.
I'll try to make a video today.
Can anyone measure the height of the top 20moa rail on an origin short action for me? I'm trying to find a means to raise my optic height while keeping my current scope mount. Curios if the Murphy precision rail will net me anything. Thanks!
Origin with push feed bolt head
I’m having trouble with a 223ai build. It Will not feed AI cases reliably. Fire forming is no problem and is very accurate. .3-.4s consistently. I have tried aics mags, mdt mags, multiple bullets at multiple oal. Had Smith chamfer chamber mouth and polish. Still no dice. Rounds bind in the chamber and leave a ring on case body. Must be manually removed. This happens 60% of the time.
It Runs smooth as silk from any magazine with vanilla 223. I assume I have a CRF Bolt head as I bought the barreled action used here.
Is the push feed bulkhead the answer? I have reached out to Zermatt asking the same question. Any help or suggestions would be great.
Thanks

223 ackley feeding issues
Hello I have an origin action in an MDT ACC chassis with Mdt metal 223 mags. The bolt can be felt dragging across the plastic insert with an empty mag. I can feed slowly with just 223 ammo, but not normal or fast speed. when it comes to the improved case it jams and a slight mark can be seen on...

It has been great actually. It shoots better than I am capable of. I have debated whether I will get another one for my next barrel, or go with something else. The jury is still out on that I guess. There is no reason that I wouldn't use another one, except that other peoples' opinions of them being a low cost barrel company has gotten in my head. But my experience has been great.
Glad to hear that. You can’t beat their production times. I’ve always been a single point cut barrel guy, just because others always told me they give you the best chance of having a good accurate barrel. I have a preferred barrel blanks barrel being chambered here shortly that I’m going to try out.

Talley rings that will supposedly work.
I didn't realize this was a thread until today.
I've had this setup for a few years now, 2018 (or early 2019) was when I received my Origin.
24 inch .223 PVA 1:7 twist (I know it's kind of stupid long). It was actually a blem, so I got it on a good discount.
KRG Bravo Chassis
Harris BRM-S bipod
Triggertech Flat trigger
Nighforce 20 MOA rail

Vortex rings (medium height?)
I use the Accurate Mag 10 round 223 AICS mags
Love this gun, thinking about building a 300 Blk SBR with an Origin and KRG Bravo for hogs here in Texas. Too many dumb ideas and not enough money.

Started gathering parts last week and my first origin build is now underway! Just waiting on a minimalist spigot and the barrel to show up, (PVA 20" 6 creed - marksman contour)
Northland special, bead blast origin
Zermatt Arms Origin Beadblast Short ActionNorthland Shooters Supply
Northland Shooters Supply (NSS) offers the following Zermatt Arms/ Bighorn Arms Origin short action with a beadblast finish
northlandshooterssupply.com
Already beat to the answer above. But yes beadblast from NSS. They had them in stock, was a few week wait for the nitride to be available, so I decided to be different, lol.
Should hopefully look good with the stainless barrel And silver trigger
Finally got it done. 20" Bartlein 5R 7.5 twist heavy palma 6.5 Creedmoor, JP APAC, Steiner T6xi, and Tubb two stage trigger. Mil spec OD green and midnight bronze Cerakote. Now I have to work up some loads.

I decided to lighten up my original build (24" 280AI and heavy Meopta scope). Barrel nut Criterion barrel with lighter Leupold scope. I am also converting to a DBM H&S Prevision bottom metal. 9lbs as pictured.
I like how the Greyboe stock blends into the old teak wood.
