Questions & Answers
What would be the dot size at 50 yrds? Expert Answer

Mueller gives the dot specs of 3/8" at 100 yards and less than an inch at 200 yards. At 50 yards it should be close to 1/8"

Does this scope come with lense caps, and if so what type? Expert Answer

These do not. However we do have Butler Creek Flip open scope covers for objective lens here https://www.opticsplanet.com/butler-creek-flip-open-scope-covers.html and for the eye piece here https://www.opticsplanet.com/butler-creek-eyepiece-flip-open-scope-covers.html all you need is to measure the diameter of the lens for each one and go .5 smaller to ensure a tight fit.

Mueller has done a great job on the engineering and QA for this scope. I've owned Leopolds and Nikons in the $450-650 price range. None match the magnification range of the Eraticator, and construction, quality of optics and zero stability are easily...

Eradicator scope by Brian, March 9, 2016

Product Info for Mueller Optics Eraticator 8.5-25x50mm Long Range Red Dot Rifle Scope

Mueller Optics 8.5-25x 50mm Eraticator Red Dot Rifle Scope has become very popular among rimfire shooters. This is due to the short range focusing capabilities and will focus down to a minimum of 15 yds. The Mueller Optics Rifle Scope features a micro-fine crosshair with illuminated micro-dot. The reticle was designed by Mueller Optics for long range shots on small targets such as prairie dogs but can also be used for long range big game hunting. The design of the micro-fine cross hair will eliminate the possibility of the the hairs covering the target at longer ranges. For normal daylight conditions the varmint reticle of the 8.5-25x50mm Eraticator Water Proof Scope has a standard black micro dot centered in a micro-fine cross hair. During low light conditions or when viewing dark targets, the black dot can be illuminated red and fine tuned with 11 brightness intensity settings. The Mueller Optics Eraticator Long Range Rifle Scope also features fine tune 1/8" windage and elevation adjustments with click stops and easy finger turrets (no tools required).image

If you are looking for outstanding clarity, light capabilities and more, then check out the Mueller Optics Rifle Scopes section of our store.
