Zero One is up and running again in a totally new format, back to our roots where we started some 27 years ago, operating online only and bringing you THE best prices in the country on what we are selecting to sell; focussing on Tokyo Marui, VFC and popular Zero One products like Blitz BB's, Tesla Batteries & Hard Cases!

Zero One is still transitioning, and more stock will become available over the next month or two as we settle in to the new future. Without a team, Zero One is now just being run by husband and wife duo, 100% family run, like the old days. We are shipping orders out super quick same/next day.

There is still plenty of bargains to be had with our warehouse and showroom closures and tubs full of stock that is to clear.

The Eotech/Holo Sight style of optic is easily one of the most recognisable optics, and if a video game, film or TV show has featured modern guns, chances are you'll spot (or unlock!) one.

Ideal for close to medium engagement distances, the ZO 551 Holographic Dot Sight allows you to get onto your target quicker. The decent sized lens gives a nice, clear sight picture whilst the classic 'Circle with a Dot' reticule is switchable between Red and Turquoise.
The Reticule's brightness can be adjusted via rubberised buttons on the rear of the Sight, whilst Windage/Elevation adjustments are handled by the easily accessible dials on the side.

The Sight's Metal and Polymer construction certainly give it a welcome robustness, whilst the four LR44 batteries (not included) are fitted in the front of the unit. Fitting the Sight to a 20mm RIS Rail is simplicity itself, with the knurled knob on the side securing the Sight to your weapon. The exclusive Zero One Airsoft engravings finish the Sight off nicely.

Not all optics can withstand direct impact from BBs and on occasion, if you are very unlucky, this can result in chipped, cracked or broken lenses. Damaged lenses are not covered by warranty. Most players take the risk and are never unfortunate enough for it to happen to them, but we recommend purchasing a BB shield to protect your shiny new optic, just in case.

Any technical or performance figures listed are based on a spot test we performed at a given point in time. These may vary WILDLY because of random alterations made by the manufacturer from batch to batch, gas pressure, ambient temperature, battery charge and so on. Some of the figures therefore should be treated as a very loose guide or indication only, based on the spot tests we have performed. The images and product contents listed are again based on a spot check we performed at a given point in time, and may differ due to changes, omissions or inclusions made by the manufacturer. If you require something specific, such as FPS, you MUST specify this at time of ordering, and take a tuning option where required.
