If you must have a sling (and you don't at home but will if you go to the range enough, and at classes yes. And you mean carry strap):
One point slings on the everything were a fad. They are only useful on a certain type of very small subgun. Do not get a 1 point. Odd balance and a good way to get a hot barrel on your legs.
Two will do.
But move the swivels to the side. As stated above, you want the gun against you when the sling is tightened up (picking slings is a whole thing, we'll avoid that for now).Bottom sling mounts don't ride as well as side mounts because the gun is a flat board with bends.
Avoid swivels. Get sling loops if you can. Keeps things from flopping, twisting, getting in the way of sights or bore, making noise.
Example front sling loop:
GG&G makes this, and a million of them. If you want to get a light on the front there, they make combined loops and rails for that.
On the back you can look for different stocks, like the very good Magpul, with a side sling loop:
...get adapters that place the loop between stock and receiver:
...or get any of many fabric adapters. Here's a pretty weird one (bottom)
This is BFG. Great slings. Only ones I have.
