Scope replacement parts
Nope you can't unless you find a donor scope for spares
Most scopes are not user serviceable due to the moisture purging and sealing required
Sight in distance for 2.510x42m
What is the calibre and velocity and target species as the zero distance could be 50-200 yards depending on what you are shooting
most of my rifles are set to 100yards except for the nitro express
Which is zeroed for 55 yrds and the 17 wildcat which is 200 yards
It all depends on the range you will be shooting most

How do I sight in a Duplex Reticile scope?
Focus the reticle on the blue sky or a wall or painted surface until its sharp with the ocular focus ring
Then set the objective to 100yards or the distance you want to zero to
Shoot a group and adjust turrets and repeat until zeroed
About my tasco 46-060675 D=60mm F=900mm come with 3 eye lense 1(sr4mm) 2 (k10MM) 3(k25MM) and two tube 1(1.5x erecting eyepiece) 2 (3xbarlow lense
The different eyepieces are to give different magnifications. This is worked out by dividing the focal length of the telescope, f = 900, by that of the EP. So the 25 mm Kellner (that is the type of optics in the EP) will give 900 / 25 = 36 times magnification.
The erecting eyepiece is used for terrestrial viewing. Normally with an astro telescope everything is upside down as that does not matter when looking at a star. So when you want to look through someone's bedroom window you use this.
A Barlow lens is an add-on magnifier. If you add this onto any EP (it normally fits between the EP and the scope) it will increase magnification x 3.
There is a practical limit to what any scope will deliver, governed by its aperture (the size of the front lens) and for your scope this will be about x 120 magnification. Beyond that the image becomes too dim and fuzzy. This means that your 4 mm eyepiece ( x 225 magnification) won't be much use. It will be hard to find the object you are trying to observe, it will be hard to focus, and the image will wobble around. Nor is your barlow lens much use either I fear.
You might consider another eyepiece around 18 mm to give a nice spread. A Plossl type is good. If you get serious about astronomy, I think you will immediately want a better scope after using the Tasco.

How to get my image right side up
For astronomical viewing this is unnecessary-- there is no up or down in space. :) For terrestrial viewing you can but an erecting diagonal which will make the image right side up.
Here is one
