Cory Trapp, Gunsite instructor and gunsmith, discusses accessorizing your AR-15 in this video from the National Shooting Sports Foundation. He discusses what add-ons you might want and what you can live without.
More importantly, he explains why some add-ons can aid your shooting while others will just get in the way. Cory makes the point that when it comes to accessorizing your AR “less is more”.
When the first thing he recommends is an IR laser, you know this isn't for the average person.
I would agree with you on that one.
