I snagged a 20" 1-9:.308 impact prefit off their website, it shoots very well from 100-600y, cannot tell any velocity or grouping difference from my 24" 1-10.
Was using 169smk, 177smk, 175botm, 175smk, 185jugs.
Getting to know my 12x DMRs.
My laser is pretty much centered, just a hair low and right of the center crosshair junction, whew!
Eye relief is not the best for wearing glasses, but better than some other LRFBs.
Also, prefer the A419 mount over the RRS.
Very happy so far.
