salvarsan from United States, TX Public Profile

Perhaps I've led a charmed existence but my FF4 hasn't been a problem. The multi-reticle feature makes it serviceable for both Steel Challenge and target. Without changing steel sights, it's low enough profile for 1/10 co-witness geometry on my Springfield XD Elite. It hasn't failed, dimmed, or otherwise misbehaved in the last 18 months.

In a perfect world, it would be a shake-awake RDS and the auto-shutoff would be after 30 minutes instead of 8 hours.

The RT-25 acquits itself well against the usual comparisons against Vortex offerings in a similar price range. You get a better balance of range, resolution, and contrast. It's inadequacies show up at the extremes -- significant chromatic haze at maximum zoom is a fact of life in sub-$1400 scopes. How much you can tolerate is the issue. Parallax adjustment is sharp and somewhat unforgiving; it pops into focus instead dialing in the most tolerable unfocus. The 20 mrad ranging reticle is nice but too optimistic. It's good enough for training out to 500 yards using a flat mounting rail. You are limited in the amount of elevation you can dial in once you've zero'ed it for use with an idiosyncratic muzzle brake that significantly shifts point of impact. The reticle rulings are a bit fine for a scope without illumination. Still, for the dollar, I'm satisfied, especially since the next level of optical quality costs twice as much.
