I've never heard of them, but did spend a little time on their website. Not a lot of details as to construction, but they seem to be well made stocks similar in construction to Brown Precision, MPI, Manners, Hi-Tech Specialties and McMillan. I don't specifically see that they offer one for the X Bolt, but that doesn't mean they don't. Not all of the stock makers will offer one for that rifle.
I've owned all of the above except Manners and MPI. They are all good stocks, but for my money it is still hard to beat McMillan. All of the others have required some final fitting and finish work to fit right that was best done by a gunsmith. Some advertise a little cheaper price, but when you factor in the work needed they end up costing more. A standard weight McMillan will run $499, the lightest weight Edge stock $599
The McMillans I've bought have bolted to the rifle right out of the box and were ready to go. I usually put a bit of bedding in the recoil mortise, but have never noted any improvement in accuracy. They didn't need it, but it is cheap insurance.
The lightest stock McMillan offers is going to be around 22 oz. I see where Pendleton offers a 16 oz version, as does Brown Precision. I don't think you'd want to go that light in a 30-06, 22 oz is still pretty light. A standard weight McMillan is going to be about 32 oz. I don't know how that compares to the Browning factory stock, but most others I've weighed were 28-36 oz.
