I am looking at building an AR in the next few months. Eventually, I want to SBR the lower. A lot of local guys I have been talking with mention getting a billet lower, but very few actually have one. So, Does anyone here have one? What are your opinions about them? Are they worth the extra 100 plus dollars just for the lower? I can get a forged lower for 80-150 bucks, but most billet lowers are 225+. What do you guys/gals think??
