The ibolt rifles also had Thompson produced barrels. From what I know about them, they were good rifles, they just couldn't compete with the big bolt action rifle companies. I have been thinking about adding an ibolt to the collection, just haven't done it yet.
Now, the best, IMO, bolt action rifles with the S&W name on them were the ones they originally imported from Husqvarna in the late 60's.
That is my S&W Model C (original names back then) in .243 Win.
