I was just curious how many of you guys have to deal with further review? When i started my ar build i got a further review on the lower. I was confused as to why because i knew i had never been in trouble. One day later i got the green light. Now i have a smith and Wesson sd on the way and if i go pick it up friday and get a further review im going to be a sad sloth. The only thing i can think of is i had a twic card a few years back for work and that required a federal backround check. The employee that sold me the lower said it was because they track ar15s. I find that hard to believe. Whats your experience with further review?
