No problem except some fitting might be required to fit barrel/cylinder gap. That's assuming it's a caliber for caliber swap.

As Bob said, "No problem".
New barrels are indexed so they tighten up in alignment when swapped to other new models. Bar/cyl gap still may need adjustment. New Model barrels in old models need adjustment for sight alignment like any typical barrel change.
Same thread as old model Blackhawks except as listed below:
Blackhawk barrels, all calibers, new and old model (large and mid frame) are:
24 TPI x .685" (11/16), (shank .618".) (same as 3rd Gen. SAA Colt)
SBH Hunter barrels are the exception: thread count and diameter varies:
.41 SBH Hunter is 32 TPI x .708" (shank diameter is .623"),
44 SBH Hunter is 20 TPI x .747" (shank diameter is .680"), (same as Super Redhawk)
.45 SBH Hunter is 32 TPI x .703" (shank diameter is .623").
New Model Single Six barrel thread change 1986:
OM and pre 1986 NM Single Six .22 barrels, and 1st year 1984 and part of 1985 early.32 barrels are 20 tpi x .557", shank at forcing cone .430" (earliest .32 I have is # 650-01300, 1st year, 1984 and latest is 650-06801, 1985 with this thread size).
Post 1985 .22 barrels are 24 tpi x .622", with the old size shank of .430" (lowest I have is #261-18748 from 1986) and .32 barrels are also 24 tpi x .622", but with shank .486" (lowest I have is 5 1/2"[cut to 4 ¾"] # 650-14117 from late 1985).

This begs the question: does Ruger sell NM barrels or do they require sending a gun in to be re-barreled? Is there another source other than Ruger, like Gun Parts Corp? If I can just buy one this is the green light for a project I've had in mind for some time. (smile)

Congrats! I guarantee it will work in an Old model. What length did you get?
Ruger never sold new barrels or cylinders. Ruger will only sell new ones if they install.
The only way to get a barrel is to get a take-off. Gun parts will not have barrels unless they are used.
Custom handgun smiths often have take offs.

I have one in that length. If only I'd have known you were looking for one.
