The only improvement would be a smaller, lighter version with a low profile/covered windage.
I have 5-6 SWFA now, and used several others from the Classified, including one 10x from Tanner, who probably wasn't the gentlest turret dial-er in his youth.
All have have worked as advertised, no failures. I bought a new 3-15 last year, and ran it from 200-1200 this summer. No issues in tracking, returned back to zero, with repeated dials up in the 40-45 MOA (2-3 full turns) range, and return.
Cons: no zero stop in the variable powers, but an easy fix.
Weight and bulk - I'm with Bean, I'd like to see a SWFA "Lite", but that may be at the risk of losing the current ruggedness of the tubes.
Smaller turrets, and covered on windage, maybe an option with covered with the elevation as well - the reticle worked as expected out to 4-500 without dialing.
