Apples and oranges comparison. The Sport is lower cost than other rifles due to less features. But the areas where the cost savings come from are not going to affect the operation of the rifle. A lack of a dust cover, no heat shields in the handguard, a semi auto bolt carrier, etc., are not going to keep the rifle from firing or working properly.
However, a lower cost optic is not the same. Battery life is typically lower. Clarity of the optic is not as good as the higher priced models. Ability to hold zero, or return to zero is not as reliable. And most of these low cost optics are feature rich at a lower price point!
Here is food for thought. Go ask Marshall Lerner, CEO of Primary Arms, for his opinion on using a Primary Optics red dot on a duty rifle, or self defense rifle. He will advise that his optics are for recreational use, not something to stake your life on.
