Your's is an opinion i trust to be truthful and free from "fan-boy" bias and am pleased to learn the free-floating bolt face is able to achieve excellent results. It has some desirable attributes.
I can't remember the "who" or even when, but i was having a chat w/someone about the floating bolt receivers. He was saying that the floating bolt simply was not/could not be as accurate as a Rem 700 type bolt.
I thought that was hogwash.... as in my experience (limited as it may be) the barrel has the single largest affect on accuracy (so long as the chamber is in alignment with the bolt face).
Anyway, the Ultimatum Precision receiver looks to have some great design inclusions.
As someone above mention, the receiver was made from a 4000 series steel (standard tool steel properties) which is good, but a lot of a steels properties have to do with how it's tempered which is never discussed in any of the articles generally referenced about rifles.
I was just wondering about the quality of machining and all that is involved with that - not just fit and finish - you can put lipstick on a hog, but it's still a hog.
