Very nice collapsible brace - SB Tactical SBPDW Pistol Stabilizing Brace for Mil-spec AR-15 Receivers

The SB Tactical pdw brace is a very well made and was easy to install on my recent build. I was surprised to see it had a built in QD sling swivel mount. Even in the fully collapsed position there was no interference with my saftey/fire controls. I gave the brace 4 stars because the brace was advertised as the only brace to receive ATF approval to be shoulder fired without being registered as a SBR. Local law enforcement and my gunsmith told me that's not correct and the ATF has put out a letter saying the no pistol brace is legal to shoulder fire without registering as a SBR and paying the tax stamp. So Shoulder fire at your own risk..
