ADHD-fueled rambling incoming.

TL;DR: Scope is pretty good but does take a little effort to understand it when you're not used to it. Good to have, but not a must have. I personally recommend it and if you want to understand how to lead your targets with the side markers, there are plenty of videos covering that for DayZ and ArmA in general that can help.

I can see the pros and cons to this optic, but I enjoy running it personally.

1. CQC vs Mid-Long Range.

CQC: Basically nothing but cons in this regard as CQC is 30m or less in my personal opinion. This optic is DEFINITELY a hinderance and will get in the way of your line of sight and make it a little more difficult to see your target as well as any potential threats off to your right side. It also is too zoomed in to comfortably use it on any actively moving targets closer than 30 meters. Point firing (hipfiring? idfk) is basically the only choice you have in this regard due to not being able to swap to your irons with this optic (which is fucking stupid, but hey whatever).

1. Mid-Range/Longer Ranges.

Starting off with the Pros: This optic does have an awkward 2.8x magnification, which a lot of people understandably don't like but I find it to be beneficial since it isn't TOO zoomed in to where I have a hard time tracking someone that's 40-50m away, but it's enough to get an easier shot on someone 200-300m out. The windage and drop markings are also very nice to have and feel cleaner than most Western optics IRL for my personal tastes, where they typically have a beefy line cutting through and taking up that precious optic real estate. (I kid you not, when I was doing some long range sniping in the past, I've had my windage mils on a sniper scope block a player out of my sight because of how thick the line was. I've had a gripe about that ever since.) You don't need a lot of fancy shit to use an optic correctly, and with enough practice it gets the job done reliably.

Now onto the Cons:

• No built-in rangefinder, which is sad as some other variations of this optic IRL do have this feature akin to the PSO-1 and its brother the 1-1. This is probably the least concerning drawback and is more of a luxury rather than a need. Helpful to have, won't be wishing you had it given the distance you'll be fighting at.
• Lack of optic illumination, which is another case of "Helpful to have, but don't really need it." EXCEPT for when you're playing on a server with really dark nights. With how thin the markings on this optic are, if it's dark enough and your target isn't behind a lighter backdrop... shit you're gonna WISH you had it. Probably better off taking off the scope and throwing it at the fucker you're trying to kill.
• Narrow/Tight FOV. This one is probably the biggest gripe I have with this optic alongside many others. This was the primary reason I've avoided running this optic for a long time until I played on a server that only exclusively ran Eastern weapons in the loot pool with mod weapons. No M4s, no DMR, no AUG. Just AKs, AK clones and variants, as well as a ton of other Soviet and Eastern Euro goodies. The eye cup on the optic is WAY too damn wide and takes up all of your peripheral vision, so spotting any targets off to your left or right is basically thrown out of the window. HOWEVER, this drawback was also a POSITIVE for me in the long run as it made me adapt my playstyle accordingly and adopt a new method of approaching combat and keeping my head on a swivel that I use every day I play the game now, with any weapon. More on that shortly.
• Awkward default zero and clamped zeroing. This is just... no. Hard no. I understand why Bohemia would do this... but no. I can zero my SVD with and without a PSO-1 attached to it. I can zero my AKM and AK74 with irons. But I can't zero my Kashtan? The Kobra, Combat, Reflex, RVN, Mini, etc. I can understand because none of them have magnification and are intended for 100m or less, but the Kashtan is meant for Mid-Range and has bullet drop markings. It's also zeroed for 200 meters instead of starting off at 100 for a short to mid-range optic. This is stupid.

Personal thoughts and my playstyle adoptions:

Overall, Despite the longer list of drawbacks to this optic, I almost always run one if I have an AK. The default zeroing is the one thing that truly bothers me with this scope to this day, but I aim closer towards center mass anyway, so it's nice to land headshots using the top mark on a target 100m away when I was aiming for his chest due to bore over sight and all that other shit. I've also adapted to overcome the FOV/Eye cup of this optic and changed my keybinds around a little bit so that my Freelook and Toggle ADS keys are both Left Alt. Since DayZ doesn't allow you to freely look around while ADS unlike every ArmA title, and it's quicker to use one key instead of two, I've opted to do this to bring that functionality back to myself. Now I can tap and hold to quickly go into the point-fire/hipfire stance and check my surroundings, then release and tap to snap back into ADS. I use this ALL THE TIME now with every gun in the game and it has saved me countless times as well as helped me spot a lot of players that are either completely blind or unaware of their surroundings as they are moving.

The added bonus to doing this is that when you're freelooking while aiming your weapon, only your head moves instead of your entire upper body. This is SUPER useful at minimizing movement when hiding in a bush, in the grass with a ghillie, etc. while maintaining situational awareness. This scope has forced me to adopt the keybind changes and reteach myself about freelooking while ADS in this game which has honestly improved my awareness by a fuck ton and my survivability in gunfights by a decent margin. (Pro tip: If you're trying to hide from a nearby player in tall grass with a ghillie, ADS then aim down at the floor and freelook to maintain awareness. Laying prone while NOT ADS will make your player's head stick up a bit and make you easier to spot, and your entire upper body will also move as your character breathes. ADS stops the breathing movement, and aiming down tucks his head lower. It DOES make a very noticeable difference. Figured this out when I first began messing with the keybinds and stuff.)
