You can install it yourself. Pretty simple. Not too complicated.
I guess it depends on aptitude and tools available.
No real major issues other than making sure everything is tight. But not over tight to strip out the threads.
The screws holding the rail will need to be checked if you decide to use the existing picatinny rail.
Or make sure the Ruger factory rings are secured to the receiver if you go that way.
That's pretty straight forward. They are directional and have to be mounted correctly. Believe there is an arrow indicating correct orientation.
You can either take it to a smith and have the rings lapped parallel. Or blow it off.
This provides a more square, secure mounting for the scope tube.
Not really imperative. But good practice if you can afford it.
Thousands of people have forgone that expense, and have excellent shooting rifles.
At this point, I always install a Wheeler Cant gauge. Personal preference.
Loose mount the scope and get proper eye relief.
Then put the rifle into a decent vice to hold it level.
You will need a set of scope levels. Pretty cheap.
One goes on top of the receiver or some place square and level to the breech. Square the rifle to level in the gun vise.
The other level goes on the top scope turret. Loosen the rings and rotate the scope level to match the level on the receiver. Re-check eye relief.
Squarely and evenly tighten the rings. Continue checking level.
You can twist the scope out of square while tightening the screws if not done evenly.
If you installed it, adjust the level on the Cant gauge and tighten.
Double check all the levels.
From this point, it's about bore sighting or paper sighting.
I prefer laser bore sighting prior to punching paper.
If you can't bore sight, start closer to your target and move back as you bring the reticle on target.
Or if it's a bolt gun, remove the bolt and visually check to see if the reticles are fairly close to bore.
Not that hard to do.
Best part is, you get to spend a little bench time with your new toy, and a bunch of time at the range burning ammo. Win. Win.
