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.

Everything a Teething Puppy Could Need — Well-Thought-Out Kit
Size: X-Small, Color: Teething Bone
The Nylabone New Puppy Starter Kit is a solid all-in-one solution for the first few months of puppy ownership. It comes with multiple chew toys and bones designed specifically for teething puppies, and my little one took to them right away. The variety keeps him engaged, and I appreciate that each item is designed to be gentle on developing teeth while still satisfying his urge to chew. What differentiates this kit from other puppy chew sets on Amazon is the thoughtful selection of textures and shapes. It’s clear these toys are designed to stimulate gums, promote healthy chewing habits, and even support dental care. I also like that everything is non-toxic and durable enough to survive a few enthusiastic chews. The only reason I didn’t give 5 stars is that the kit might be a bit small for larger breeds, or for puppies that are particularly aggressive chewers. But for standard small to medium pups, it’s a fantastic starter kit that keeps both puppy and owner happy. ✅ Bottom line: A reliable, well-designed starter kit for teething puppies which is thoughtful, durable, and engaging. Makes a great gift for new puppy owners or a practical addition to your own puppy’s toy collection.

Chicken Flavor Good, But 🔄 Rotation-Resistant✖; Best for Simpler Chewers
Size: X-Small, Color: Ring Bone, Size: X-Small, Color: Ring Bone
🐾 Hi, I’m PVD; plush sophisticate, chew critic, and active curator of rotational toy relevance. This ring bone and I never fully bonded. I sampled it maybe five times in my entire puppyhood before quietly returning it to the bin (with a single judgmental glance). Still, it does have value for the right pup. ⭐ Why I originally wanted to love it: ✔️ XS size works well for very young puppies ✔️ Chicken flavor lasts impressively long ✔️ Freezing offers temporary gum relief ✔️ Durable and safe; no odd odors or shredding 🌀 Why it’s now a respectful 3-star chew in my rotation: ✘ Never became a go-to toy (5 uses max in my life) ✘ Ring shape felt awkward, not natural or chic; hard to grip and maneuver ✘ Texture too tame vs. nubs or detailed chew surfaces ✘ When I was smaller, I much preferred the Nylabone Baby Blue Bone Chew Toy with nubs (my personal classic), and have since matured into nightly Nylabone “Nubz” edible bones This Ring Bone is Best For: • Very young puppies with minimal chew preferences • Dogs who like simple textures and circular shapes • Those just starting enrichment chew play • Freezer treat rotations (briefly) 🚫 Not ideal for: picky pups, advanced chewers, or dogs who analyze toy ergonomics (like myself). 📝 Final Re-Barks: A strong, well-made chew, but lacked the intrigue to make my permanent rotation. Works for basic chew enjoyment; not for pups with elevated taste or toy ambition. — PVD (Chew Strategist, Textural Analyst & Aspire-to-Vine Reviewer 🐶💼)

Puppy loves it!
Size: X-Large, Color: Teething Bone, Size: X-Large, Color: Teething Bone
My small puppy loves this bone! I originally purchased this for a larger dog, but my small 10 pound puppy loves it more. It’s good quality and a softer material for puppies!

A hit, but could be stronger
Size: Medium, Color: Ring Bone, Size: Medium, Color: Ring Bone
Gave this to my 11 week old pittie, and she did significant damage within 15 mins. She left a pile of chewed bits on the couch but thankfully didn't eat them. Definitely don't leave unsupervised. That said, she LOVED it and it seemed to help her teething gums so, I'm still giving it a 4/5 Puppy pics for tax
