While CRYOGENIC TEMPERING would be a plus I doubt I would do it to a A& B Barrel, were it a Lilja, Krieger, maby a Shilen or Lother Walther etc. then yes, I probably would. The A & B barrels shoot pretty good but the tollerences are between .002" & .003" and the max runout is .005". That is why they are "budget". Tight tollerences translate into higher price. To give you a idea of the difference a Lilja has a max runout of .001" and a sporter barrel will cost about $275 not threaded, chambered or crowned. The A & B barrels are prone to foul much also due to a rough bore as compared to one that is a premium lapped one. The A & B barrel serves a good purpose for those who wish to keep cost down.
