Welcome to the friendly forum. The whole purpose of a scope is to allow you to see your target better regardless of the distance you're shooting. A red dot simplifies & therefore speeds up target acquisition. You're wise to get used to your rifle before you start modifying it. No modification will make up for lack of practice (although a lot of newbies try that). I have no clue what a good bargain brand would be, for target use only a cheap one would likely be fine but for defense use I'd recommend the best you can afford. Your call as to whether it would help or not.
