Ive been doing some looking around and am going to try to raise some funds for my first ar but I have no experience with them what so ever. Ive never even shot one. It seems like every upper I have looked at ask if you want to add options. The two im seeing the most are charging handle and bolt carrier group. My question to you is what exactly are the functions of these two items and are they good to have? Thanks in advance, Josh
