The Zero Compromise Optic ZC420 combines excellent optical performance with unmatched mechanical precision in the best ultra-short design ever developed.

With the highest levels of mechanical precision, flawless optical performance, and extreme durability, this compact scope easily competes with much larger riflescopes. At just 325mm (12.8 inches) in length and 986g (34.8oz) in weight, it's ideal for any application where size and maximum performance are paramount.

ZC420's 4X low magnification range provides a wide field of view (28 feet) for rapid target acquisition and close-range action. While at the top end of its x20 magnification, you've got a long-range shooter's dream where target engagements up to 1000 yards and beyond are in range.

The riflescope's mechanical system allows 35 mils of elevation adjustment for extreme long-range engagements when required. Never before has so much performance been combined in such an elegant and compact riflescope.


UNSURPASSED OPTICAL PERFORMANCE

ZCO's optical engineers have set the next standard for clarity, light transmission and resolution in a compact scope package. Never before has such performance been seen in this magnification range and lens size. Total light transmission is 92% while maintaining excellent colour fidelity matched with best in class resolution for the ultimate viewing experience.


Features
  • 36mm Main Tube
    The tube delivers optical and mechanical systems that work in unison for supreme performance; no compromises. With more internal room, optical components are better protected to withstand external distortion, stress and impacts. Further, extra room means ZCO can deliver larger lens components for remarkable optical quality, while providing massive amounts of elevation and windage travel. In this case, big is better; significantly better.
  • 50mm Objective with ED lenses
    ZCO scopes use Extra-low Dispersion (ED) lenses for the objective components to maximize resolution, colour correction, and contrast. These larger lens components bring better light transmission, flatness of field, and premium resolution.
  • Multiple Illumination Settings
    The illumination ring can be off, low light, 0-day time brightness, and shooters can choose between red and green illumination. (Including levels compatible for night vision.)
  • AIM Automatic Illumination Management
    ZC420 uses advanced sensing capability to detect when the rifle is out of shooting position to conserve battery life. Illumination is deactivated by the AIM when the scope exceeds 75 degrees in up or down angle tilt or when exceeding 45 degrees to either side.
  • Fast Focus Locking Diopter
    Provides rapid, precise reticle focus. Its lock ensures diopter settings aren't unintentionally changed.
  • Rapid Parallax Adjustment
    An excellent balance of speed and precision making it quick, accurate and naturally easy to establish a parallax-free image with zero backlash, even under heavy mirage or other challenging conditions. This is accomplished in about 190 degrees of rotation. Dial rotation is smooth with a lot of travel for maximal precision.
  • Turrets like no other
    Very audible, super-precise, perfect visual alignment and lockable; these turrets provide the ultimate in consistency and repeatability. Elevation and windage click-spline mechanisms are built using hardened steel that's eroded cut for the highest level of precision. They also have a large adjustment range for elevation and windage travel.
  • Maximum Field of View
    Industry-leading eyepiece lens design delivers maximum field of view (28.0' degree FOV) a substantial eye box, eye relief, and flatness of field. The eyepiece is built for comfort, even in all day use.
  • Magnification Change Lever (MCL)
    Machined into the magnification ring so it is ergonomic, snag-free, won't hinder bolt manipulation. ZCO gives great consideration to rotational torque of all controls, so rapid changes of any control are possible with smooth and consistent torque even in freezing conditions. The magnification ring is slightly raised and its numbers enlarged so it can easily be seen and accessed from a shooting position.
  • Real Rugged
    Every material has been carefully selected for its ability to withstand constant cycling without compromising its performance. Critical junctions and mechanical areas are stronger thanks to a thicker cross-section in specific areas.

Not a fan of this one
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I am not a fan of this product. As many of the reviews noted, the flavor is very strong. I was surprised it wasn't more minty. This is a very herbal concoction. It also tastes of the other very strong herbs, especially the rosemary. According to the instructions, this product should be used once a day for 30 seconds. I prefer a product I can use twice a day for 45 seconds to a minute. My experience is that it takes 30 seconds just to crush it up enough to swish it around and I don't have enough saliva in the morning due to overnight dry mouth. I have to add a little water. The tablets never crush completely and leave a mess in the sink that has to be carefully rinsed away. If I use them more often, my mouth dries out too much and tastes like the tablets all day long. It's not a bad taste but I expect it to go away after a half-hour (or so). They are really chalky. The container isn't bad, but doesn't pour 1 tablet out at a time. Meh. I don't like touching a bunch of them each time. There is a desiccant packet in with the tablets to protect them. I am not sure this would stay closed during travel or be allowed on a plane in carry-on. It should travel ok otherwise because it's not a liquid, but I haven't tried it. I will probably not buy this product again, but in all honesty, I have bought far worse products and been disappointed far more by them.

Its like they knew what I prayed for🙏🏽
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Okay, let me start by saying I am a huge skeptic. I need to research things to the nine's and read legit reviews before I buy anything new. I have had cavities from a very young age and receeding gumlines all my life. At age 50, I have gone all natural, got rid of everything toxic, and got really healthy. I have been listening to Dr. HUBERMAN podcast on you tube and found one he did on oral health. He gets very detailed about how to heal your oral health. He spoke specifically about hydroxyapetite and xylitol and their benefits. I then started searching for mouthwashes with these ingredients because i am seriously concerned my teeth are going to fall out from these receeding gums. I have been told all my life there was nothing you can do. I knew in my gut that was a lie. I knew there had to be a way to heal our mouths naturally. Then found BOKA. I got them. I tried them. I lOVE THEM! They are perfect! They are minty fresh, easy to use, makes my mouth feel clean and if they actually do heal my mouth....then awesome sauce! I read all the reviews. I see the after taste. But, i think its a personal choice. I like the after taste. It tastes and feels like a clean mouth. I feel the tinglyness. Yes. But I believe from my health and science background it is the mint, aloe, probiotics and everything else stimulating the skin and blood to start the regeneration of skin and mineral. Im happy to report back again in a month or so with outcome plus before and after photos👍🏽

Great Clean Alternative to Traditional Mouthwash, LOVE this!!
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I’ve been really impressed with these Boka mouthwash tablets. They’re fluoride‑free and alcohol‑free, which is exactly what I was looking for, and the hydroxyapatite is a nice bonus for supporting enamel without the harshness of traditional mouthwashes. The tablets dissolve easily, the flavor is refreshing without being overpowering, and there’s no burning sensation at all. Do NOT chew and swallow like I did the first time. Chew, get salva going and swish. My teeth never felt so clean!!! I also love that they’re travel‑friendly and cut down on plastic waste compared to big bottles. My breath feels fresh, and my mouth feels clean without that chemical aftertaste. If you’re trying to switch to a cleaner, gentler oral‑care routine, these are a great option.
