lee have you looked through a lightstream? The mildot ret is bold a but manageable, glass is pretty good and they go for reasonable money they are FFP (first focal plane) so ret stays in proportion with focal length. Only issue is they are front parallax but for HFT/SFT maybe not an issue
there is one going for good money on here at the mo.
I like using mine
FTP900 +Sightron S111 10-50 x 55
AA Pro Target in FWB FP70 stock + MTC Mamba lite
Daystate Airwolf + Bushnell Elite 6500
