Frequently asked questions

How long does shipping take?
The Core ships in 5 business days or less.
Will my Universal Mini Chassis be bolted to the stock when I receive it?

We don’t bolt the UMC to the stock so you can see how it works.  New action screws are provided that you will use to bolt your rifle to the UMC that are in the bag with the UMC packaging.  We recommend 45 in lbs to bolt the UMC to the stock and 45 to 65 in lbs (whichever you prefer) to bolt your rifle to the UMC.

The Ruger American and Mossberg Patriot rifles must be bolted onto the UMC first and the trigger guard pinned into place before bolting to the stock.

Do you ship internationally?

Yes we do, you will need to register with our exporter here, https://easyexport-web.azurefd.net/signup-purchaser before we can ship your order.

How do i purchase a Universal Mini Chassis (UMC) by itself, to use on another rifle I own in the Core stock?

You can purchase additional UMC's on the Universal Mini Chassis product page and add them to your cart before checkout.

I have a Ruger American .308 and a Remington 700 .7PRC rifle, I can really shoot both rifles in the same stock?
That is correct. You get a UMC for your Ruger American .308 (short action length) and a UMC for your Remington 700 7PRC (long action length) and they both will plug and play in the stock.
Will my rifle hold zero after i sight it in and remove the UMC with the rifle on it out of the stock?

Yes it will. Once you have sighted in your rifle on the UMC in the stock. You can remove your rifle keeping the UMC on it and it will hold zero.

What are the torque specs?
We recommend 45 in lbs bolting the UMC to the stock. Anywhere from 45-65 in lbs bolting your rifle to the UMC.
Do I use my factory action screws to bolt my rifle to the UMC?
No,we will send you a new set of action screws in the package with the UMC that must be used to bolt your rifle to the UMC.
Do you make the Core and UMC's in left hand?
Unfortunately we do not at this time. We hope to offer left handed UMC compatible stocks in late 2026.
