My pea brain says to me it is because they want list price and their gunsmith to install and charge me for it and shipping both ways is on my dime. It is a drop in barrel and can be done in 1/2 hour or less. I loved my 30" inch Savage barrel and not in love with my Shilen 28" replacement.

Is there another reason I may not be seeing? When asked, the answer was company policy.
