I have mine mounted on a 16" 6.8SPC recce-type rifle. I haven't used the scope much yet, as I just got it in last week.
SWFA is redesigning the illumination knob battery cap and will issue replacements once they are ready; the current design allows the battery to bounce around too much, resulting in brief shutoffs when firing. Frankly, the battery spring looks like a part from one of my son's $0.59 grocery store flashlights. Hopefully, SWFA will upgrade this part significantly. When the illumination is working, though, the highest setting is daylight useful in almost every setting imaginable (other than looking at a snowbank in the noonday sun). Of course, since the reticle is etched it stands out very well against light backgrounds even when the illumination is not visible.
The scope is very nicely built and the FFP circle/milscale reticle is intriguing and seems very useful. At 1x the circle is fairly small in your FOV and when illuminated it draws you eye very quickly, almost like an Aimpoint or Eotech, although without the unlimited eye relief of those true 1x scopes. At 4x the mil scale is very usable for ranging and holds. I got the capped adjustment knobs because I'm using the scope as a "combat-type" optic for COM shots vs trying to shoot bugholes, so there's no need to dial or hold from 0-200 yards and the holds past that are fairly simple to remember. Plus, I just don't see the need for target-type turrets on a 4x scope, especially ones that don't lock. That is just my opinion, of course. Of note, the knobs are 1/10 mil, 10 mils per turn, no zero stop.
Glass is very good, with excellent coatings. For me, though, it's a bit tricky to bring the entire reticle into focus at 4x unless my eye is placed exactly centerline with the scope. So in that sense, the scope is a bit sensitive to head position.
Overall, I'd give SWFA a huge round of applause for an excellent effort. It is quite a feat to get an FFP scope with a useful reticle and very good illumination and glass onto the market for less than $800. The lifetime warranty doesn't hurt either.
