I'm looking for the same thing. I have a
huskemaw that I would like to get a MOA turret for. The Huskemaw people won't cut one; they will however gladly build a "custom" calibrated turret for $$$ what ever they get for one.
I had the "custom" turret that came with the price of the scope re-anodized hence it is blank but the machine shop doesn't have the means to re-engrave it in MOA.
As for Kenton Ind., I got the same answer last year; they won't do a 1 off engraving... even though I would supply the blank turret.
I like the scope. the elevation and windage knobs track nearly perfectly. Having it mounted on a 1 piece picatinny rail mount allows me to move it between several rifles. I've figured out the offset to re-zero when it is moved between rifles. I just don't want to have to buy a dozen turrets to cover each load and condition.
