Short action REM 700 size Grendel builds

[Draftpick]

I would like to build this but I think it would end up to heavy, but wanted to pass the info on for any one else. Bighorn Origin action, 700 footprint for stocks and triggers, has replaceable bolt heads and can get ppc/grendel head, takes savage small shank prefit barrels/nuts. Carbon 6 barrels does prefits for small shank savage barrels and they do the grendel chamber and and 6mm ARC have barrel lengths from 16-26 inches. And use the new MDT 10 or 12 round metal 6mm ARC AICS pattern mags. Using this combo action & carbon 6 barrel gets a custom grendel with plenty of stock and trigger options. I have not used carbon 6 before but they claim you should be able to get 1/2 MOA.

Sounds interesting, but expensive, did you price out a complete build by chance?

Why not just use a Remington 700 donor gun or action? I used a .223 and opened up the bolt face. Still plenty meat left for strength. I used a BDL hinged fore plate. Had to use a .308 mag well (cause larger case dia.) and fabricated a piece of metal to shorten up the length. Used the .223 follower and opened up the feed ramps slightly to get consistent and reliable feeding.
PM me sometime and I will text or email you some pictures.

There are a few Grendel M700s out there, custom work of course.

Because I was looking for a build that did not need any custom work done, all these parts are plug and play, that if you can turn wrench’s you could build this and not need a gunsmith, and the quality difference in the Origin vs Remington is worth the money, and being able the buy factory bolt faces vs having to permanently alter a bolt, that versatility is worth something as well IMO.

Yes it’s expensive, and not on a mini action like the Howa, Cz 527 are that I would prefer. The Origin action is $850+- the dealer, a carbon prefit is $650-700 depending on options reasonable for a custom carbon fiber barrel, plus what ever stock and trigger you want, MDT 10 round 6mm ARC mag is $75 I think.

I believe I have seen some other barrel mfrs that do a remage style barrel, that would go onto a Remmy 700 action but has the barrel nut. Using one of them could save you some money and still be really good.
But any Rem 700 action would work under these circumstances also, it's the barrel/barrel nut that allows you to DIY.

Yes but the issue find a correct bolt head, Remington did not make a grendel, so your adding cost for a gunsmith and I have not seen any 700 actions less than $500 add bolt cost and your not far off the origin cost and I would say is a better action. If you have to ability to do your own machine work then a 700 might be the better option to save a few hundred $$. Again not everyone has the tooling or skills, this option while expensive is something 99% can build.

Buying an action for $500+ and a bolt from PTG is another $236 your at $750+ add in the cost of a pic rail and your less than hundred dollars than what the Origin cost and to me is a better action. Unless you got the Remington action for dirt cheap I would not go that route to save a $100 buying new right now. Yes I like to save money but there are times it's not worth it. I have a Remington 783 that I got really cheap but finding stocks is not easy and while I can find some barrels for now, the 783 is discontinued can I find drop in barrels in 10 years? I have looked for extractors and that is not easy, while i got the action cheap and I really like it It is really limited and not worth to me investing a lot of money on a discontinued action that does not fit Remington 700 stocks and parts.

I just sent $1500 bucks to Northland Shooters Supply for an Origin action and a steel barrel with a bunch of options. Stock, trigger, and bottom metal maybe another 1200?

last year I put together one using a .308 Shilen barrel and shipped to the door it was $2500. That was with competition bolt knob, KRG Bravo stock, 20 MOA bolt rail, tax shipping etc. Twenty Five hundred sounds like a lot but for what you end up with it is extremely reasonable. That rifle will shoot right with customs costing 3 times what I have in it. The big plus is with the Bighorn actions have interchangeable bolt heads. once you have the action, the stock and the trigger can use it as a switch barrel for any cartridge you have a bolt head and barrel for.
Bolt heads are available in:

.378" (223)
.422" (Valkyrie/SPC)
.445" (PPC/ARC/Grendal)
.473" (308)
.532" (Magnum)

I have a carbon six remage 280ai barrel on my 700 action... First combo of powder and bullet I tried had it shooting under 1/2moa in short order. It still holds 3/4 moa 1500 rds later without tweaking the load yet.
