I got this scope on a whim. I have several rifles, so I figured I'd throw it on one of them, and see if it was worth the money. My initial intent was to put it on my CZ 452, which I did. This required a different set of rings than the ones that are sent with the optic, but that was an easy fix. End result was awesome, if you're okay with a huge scope on a rifle...with one exception. The only way I could mount it resulted in the front bell of the scope resting on the rear sight of the rifle. I was worried that this could flex the optic, and affect its performance, so I went with plan B. The optic now sits atop one of my long range AR-15s, which meant that the original scope rings could be used after all. Score.Now, I didn't have high hopes for this optic. But three things made me take a chance on it. First, even though it has a lighted reticle, it's also got a black reticle, when the lighted option is turned off. I hate magnified optics that rely on batteries for their usefulness. So that was already a point in its favor. Second, it's cheap. Worst case scenario, I spent as much as dinner and a movie would cost (at least), if you were taking someone worth the time out for that sort of thing (If they're worth it, don't be cheap, fellas). And lastly, the turrets were hand adjustable. I don't see why the concept of a knurled knob is so difficult for so many optic makers to grasp, but they should all come that way, in my opinion. So those three things, I decided to get the scope, despite my low expectations as to the function. On to that....This thing was great. I sat at a 100 yard range, and focused in on individual stalks of reeds in the brush above the berm. I was quite impressed with the clarity of such a low priced optic. Eye relief is awesome, so you don't have to struggle to find the sweet spot while mounting. Once I had the optic set up the way I wanted it, turret adjustments were distinct and easily noticeable, with both audible and tactile clicks. The only thing I disliked about the setup was having to re-focus when changing distances. The focus on the end made it hard to work the adjustment while staying on the scope, which was necessary to fine tune the focus. That's going to be an issue with any focus system like this, but this one seemed quite stiff, and made adjustment take longer than I'd like. This would be fine for punching holes in paper, but if you had to do it to take game, competition, or for any shot that required speed, you're going to have issues. Not insurmountable issues...but issues, none the less.So how did it shoot? This optic was one of the easiest to get on paper, and sight in, that I've had in quite some time. I basically Billy Bobbed it onto paper (Kentucky windage until I saw that it punched a hole, then adjusted accordingly to get it closer to where I wanted it), and then dialed it in at 30 yards. It held its zero from shot to shot for the duration of approximately 30 rounds of 5.56 (actual 5.56...not .223. So a bit snappier recoil than the .223 ammo. I figured it was worth mentioning, in case anyone cared) during the sighting in phase.Now, it was about 40 degrees, with the ocassional breeze dropping it down to approximately -68 degrees (I'm going by my best guess on that second assessment. It felt pretty damned cold to me, so I was freezing my ass off. YMMV. Moving on...), so admittedly I didn't put in my due diligence putting this scope through the paces. I didn't drop it or, much with it to test how resilient it was in holding zero, but I can say that, at 30 yards, I created a single hole grouping of 3 shots with this optic, after speed zeroing it (See pic). Now, this isn't that impressive with this powerful of an optic, at such a close range (but, aside from spreading the group out a bit, a 30 yard zero should be fairly close to a 100 yard zero), and I didn't have the chance to stretch it out after that (I was in no mood to dawdle in that kind of cold), but I'm pretty impressed with that kind of performance out of a cheap optic, especially considering the less-than-methodical manner in which I was assessing it, and the weather conditions. If I hadn't been cold as I was, I could have probably tightened that group up a bit. I have yet to check it, but from initial inspection, I believe it's possible to reset the zero on the optic, as well. If that's the case, I'll bump this rating from a 4 star to a 5, since I was on the fence as to whether I should just give it a 5 star to begin with. The only reason I did was because I have yet to be able to put this through some torture testing, long range shooting, and such things as resetting the turrets.If you're looking for a light duty long range optic, something for the rifle you rarely shoot, or something to use while you're saving up for your Nightforce, Leupold, Schmidt & Bender, Zeiss, or US Optics scope of choice, this is a handy little option, with the added benefit that buying it won't set you back much monetarily on your journey to purchase one of the previously mentioned optical powerhouses.
