Hey need some advice. I did my first AR build and when I went to load it the bolt carrier couldn't and had a hard time pulling the bullet from magazine. I've noticed that 2 putts 3 are really hard to reload and i used one of those hard reloading ones when I took my first shot. I'm worried that there is more going on than just the mag being to right. I hand loaded 2 bullets and just took 2 shots because it was late
