Im not trying to flame here. Just trying to make an honest, well intended contribution....
There are a lot of fantastic optics. With a 25 ounce limit you can easily find a great optic. However, I 'd argue that such a 20, 22, 25 ounce optic would be well suited to the typical 8, 9 lb precision rifle.
If you havent actually tried a 20+ ounce optic on a featherweight rifle like the fieldcraft, I would strongly urge you to run some form of mock up and 'try' the combination befire spending $1000.00+ on a heavy optic. This is purely s personal observation but a 25 ounce scope on a sub 6lb rifle is a terrible idea: the handling is all out of whack, super top heavy, and ill balanced. Grab a short length of 1" iron pipe, sine threaded caps and some lead shot. Mock up a 25 ounce dummy, and mount it to your barret. Try before you buy....
Ive run a few lightweight rifles. Im not super experienced but id be running 16 ounces MAX on a 5.5 lb rifle. Ive got a Leupold VX6 2-12 and love it, but still looking for a lighter optic yet for a Fieldcraft. I'd be MUCH happier with 12 ounces....
Im not saying anyone is 'wrong'. Just suggesting you mock up the weight, mount it, abd handle the rifle with that much weight up top before making a big decision.. And 25 ounces isnt light weight. Thats an absolute boat anchor by hunting rifle optic standards.. .
