I love the look of a classic FSB in an AR. I’ve built several AR’s with them. I used Armalites’s clamp on A2 FSB in the bast and loved it. Unfortunately they were discontinued so I had to find a replacement. I found the Dez FSB and am even happier then I was with the Armalite FSB. The Armalite uses two screws at the bottom to literally clamp the gas block to the barrel. Not a bad design but not as effective as the Dez. It uses two set screws on each side to lock against the barrel which seems more secure. The fit and finish were great as well. It’s been around 700 rounds since I built the firearm and it hasn’t budged.
