E330 - I think you are comparing older sleeve jobs done on the cheap for salvaging cheaper guns to more recent sleeving jobs done to relatively more valuable guns. In the current case, more customers are willing to spend more money to salvage a gun. However, it remains real iffy to recover the cost of sleeving at the time of gun sale. This tends to drive down quality in an effort to keep cost down. $2000 spent on the barrels of a $1000 gun in hopes of making it a $3000 gun is risky; $1200 to make it a $2200 gun is a better gamble in most peoples' math.
