R700 AICS AT Chassis 300WM to 308Win conversion possible?

[Boyydavid]

Hey All,

I’m new here and new to this type of build, I’ve been trying to do research on possibly doing a multi caliber build on a AICS AT Chassis. But haven’t been able to find much and whatever information I could find wasn’t too helpful on the internet.

I was hoping someone can guide me in the right direction about going about this.

I’m planning to get a R700 Long Action 300WM AICS AT Chassis. Is there a possible way to convert this chassis to shoot .308win?

So a couple questions I have:
1. If I buy a separate barrel + action for .308 would I be able to put this on the 300WM AICS AT chassis?
2. If I am able to do the above, the next problem will be the magazine. Is it possible to load .308 AICS magazine into a 300WM Chassis with a type of conversion? Or is modifying a 300WM magazine to feed .308 the only option?
3. If this is possible, what needs to be done to make this happen?

*Assume money and practicality is out the door. Is there a way to accomplish this build on one chassis with multiple barrels/actions/magazines

You will be money and practicality ahead just buying 2 complete rifles.

1) No
2) N/A
3) Not possible. You would need to drill new action screw holes in your stock/chassis, then also make a new place for the recoil lug to fit, reshape/fill or some other bastardization to the magwell and somehow be able to take that shit out so you can go back to 300WM.

You can use 308 in a long action. It just needs another bolt and magazine for the smaller diameter cases 30/06,280,270.

That seems pretty straight forward, no other modifications needed from my understanding.

I didn’t even know they made a long action .308 magazine! Thanks!

That should be it. I shoot 300wm and 280 out of my long action. Just barrel bolt and mags.

Thanks guys! Appreciate the help!

Check out the long action zermatt origin my man. I would snag one from northland shooter supply and a savage take off barrel for peanuts and be off to the races. If all you are shooting is 308 for now the 473 bolt head is what you are after, and you could always get the other bolts and accurate mags when you go down that rabbit hole later. If you dont have the chassis yet good luck, ai has started to discontinue them so go after that first If you're doing it piecemeal.
