Hey all, first time posting. I have a M&P 15-22 on order and have a few questions. First are the front sights removable? I heard they get in the way of most optics. Second....whats a decent red dot for just plinking or small game hunting? BSA decent? The gun is primarily for plinking with the kids during the summer, but I thought it would be a fun little gun to hunt squirrel or rabbit with. I would prefer to stay under 50 dollars for a red dot but from looking around I don't think that's possible. Looking for any input and thx in advance!
