1-4x20 = a variable 1 to 4 power magnification, 20mm objective lens. 1x (or 1 power) magnification means no magnification. 4x magnification DOES NOT mean it's 4 times as big, it means an object looks 4x closer. In other words, a 100 yard object at 4x looks the same as a 25yd object with the unaided eye.

Inside a scope there's a bunch of lenses, the forward-most one is the objective lens (i.e facing the object). Among other duties, that lens gathers light, so the larger that lens the brighter the image.

General rule is don't buy cheap. Second rule is don't buy on paper specifications. Everyone buying their first scope looks at Barska or UTG and is dazzled by the 3-25x45 "tactical delta team elite sniper laser rangefinder" scopes for only $50 when competing Zeiss or Leupold scopes are $900+. So those Barskas must be great bargains right? No. Not everybody can buy a bunch of $900 scopes, but even a $150 Nikon or Vortex would be a better buy.

What do you mean by "long distance"? For a .22 caliber, that's 75-100 yards. For a .30 caliber or larger, it's 100-200 yards. Those are standard distances for air rifle benchrest competition now.

For up to 100 yards, you might consider a 4-16 power (x), even up to a 6-24 power. What that means in practical terms is that, say at a 100 yard target distance, with the scope set at 10x, the target would appear magnified as if you were looking at it with the naked eye from 10 yards away.

The last digit refers to the diameter of the optic's front (forward) element. That's an indication of how bright that scope would probably be. A 6-24x50 would mean a scope with a variable power range from 6x to 24x, with a front element 50mm in diameter. That would have a brighter image in the scope than a 6-24x44 but not as bright as a 6-24x56, all other things (like optical elements inside) being equal. Brighter usually also means more expensive but not always. You can get great scopes at decent prices.

Also, if you're talking about a break-action "springer" pellet rifle, do NOT use a regular rifle scope. The trauma of a springer's action will tear a regular scope apart. For PCP (pre-charged pneumatic) rifles, no problem using a conventional scope. PCP rifles are definitely my preference.

^^^^^

All the above post is spot on. Good advice. There is a distinction however with first focal and second focal planes;

First focal is when the reticule adjusts size with the power, larger or smaller and the scope does not need elevation or windage adjustments when moving from power to power. These scopes are usually more costly.

Second focal is when the power is changed, but the reticule remains constant size, needing to be elevation and sometimes windage adjusted to match. These are the most common scopes out there and less expensive (usually).

Couldn't resist... My RAW (Rapid Air Weapon) .30 PCP rifle with a Vortex Viper HS 6-24x50 scope. Awesome for practicing the fundamentals of my conventional long arms at a fraction of the cost per round.

Had to laugh. That's about a $2000.00 gun (not including the optic) and you're concerned about ammo cost.

BTW, awesome air rifle!

Granted, that's kind of like a Tesla owner saying how economical his electric car is... And no, I don't have a Tesla nor am I likely to ever get one.

In my defense though, you can find really fun, accurate air rifles for the price of a Glock. And those rifles shoot the same pellets as the competition rifles. Not that a squirrel would know the difference.
