Here is a 10/22. The only thing ruger on it is the receiver. Everything else is aftermarket. If you have tactical foregrips,you should be able to add just about any toys to it later. I have quite abit into this gun,but it was fun buying all the different pieces exactly the way I wanted and build my own gun.It is extremely accurate with the red/green dot scope. You can just about circumcise a gnat at 30 yds.
There are some nice guns listed above already that are bad to the bone right out of the box. You might look into the Archangel too.
