I have zero experience with this optics brand, so I was hesitant while ordering it, but I wasn't disappointed. I've owned many scopes over the years, for different rifles and different purposes. I am quite impressed with this "DISCOVEROPT" scope. It has a BDC style reticle, which I like very much. The scope is nitrogen purged and fog proof, but I did not expect otherwise. Most importantly, it's FFP! Right after taking it out of its box, I've noticed that it's pretty heavy, but I think that's ultimately a tribute to its solid construction.It's a high quality, very well purpose-built scope that will serve you well. Magnification can be easily adjusted between 1x and 6x by turning the ring located on the eyepiece side but it's missing a throw lever that I like to use instead of the ring. Focus adjustment is also available on the eyepiece end of the scope, which is great, I hate it when the scope does not have such a simple feature as focus. Focus and magnification rings move smoothly, which tells a lot about the build quality of the scope. Windage and elevation turrets are very large - these are the largest scope turrets I've ever seen! You can easily do adjustments with your fingers, and they are covered by caps to prevent damage if the scope is dropped and protect against accidental change of position. Unfortunately, there is no zero stop feature on this scope, or at least I did not figure out how to do it. I really liked how the turrets adjustment works, I can feel and hear distinct "clicks" when I adjust it and turrets have practically no play at selected positions.The scope is illuminated in red color only. I normally do not even consider a scope that does not have illumination because it greatly limits its usability, especially in dusk and nighttime. I would have liked it if there was also a choice of green illumination color because red is great for night and green is great for day, dusk, or dawn. The scope has exceptionally clear optics, I did not notice any distortions even at 6x magnification, which is good. The reticle is etched on the glass and is very sharp. Note that illumination lights up the entire reticle. The brightness knob is extra-large as well, easy to operate, and not too stiff. The number of brightness levels is limited to 6 only, while the knob is so large that they could easily have 12 levels.I need to point out that 1x is not exactly 1x. Close but still a tiny bit different. I think it's about 1.05 to 1.1 times. It's close enough that you can shoot with both eyes open for about 10-20 seconds before your vision starts to play tricks with your vision. This works fine for the initial engagement, but eventually you will need to close your non-dominant (support) eye during sustained fire. It's not perfect, but for about $100 it's pretty damn good.The scope comes with two 30mm rings, that's not that bad, but not good either. I noticed that cheaper scopes usually of low quality include rings that I always throw away or give away and buy a new set of quality rings that might cost you as much as the scope itself. This time I probably will keep the rings as spares and replace them with something more reliable and of higher quality.Pro-tip. While the scope's reticle is fairly complex and provides guidance for elevation or windage adjustments, you still need to zero it first. Your best bet for zeroing it is to use a laser bore sighter. Just insert it into your barrel and zero your scope's crosshair on its dot. Then on a range you can finish fine-tuning your aim at 6x magnification according to the manufacturer's guidelines. This will save you tons of ammo.Note that the scope description on the store page says that it has Parallax adjustment. IT DOES NOT HAVE PARALLAX ADJUSTMENT. I have not seen a scope below 9x magnification level to have one. You simply don't need it on low-magnification scopes. Ignore it, this is a mistake in the description.*** TL;DR ***Yes, I do recommend this scope to every gun enthusiast. It has truly clear optics, magnification from 1x to 6x, which is perfect for a close quarter aiming at 1x. Eye relief is outstanding. The reticle is a highly effective BDC-style one, which I like very much for its visual aid for elevation or windage adjustments. All adjustments work fine. Plus, it has red illumination. What else do you need? For 100 bucks this is an unbelievable deal on FFP you can't beat, and it even comes with fairly good scope rings. I'll go with a 5-star rating, outstanding budget scope.+++ Pros +++1) Very well built.2) It's FFP!!!!!3) Lifetime warranty!!!4) Magnification 1x to 6x.5) Outstanding BDC reticle.6) Fast target acquisition.7) Eye relief is outstanding.8) Turrets are protected with caps.9) Comes with nice lens caps.10) Reticle is illuminated in red.11) Comes with rings.--- Cons ---1) No parallax adjustment.2) Only 6 levels of brightness.3) Only red color of illumination.4) Included rings are so-so.5) Heavy, 629 grams (without rings).
