The micro QD mounts are off the hook. I have two on my troy alpha rail mounted on the bottom towards the end of the barrel and the other near the reciever. It was a PITA to mount the one on the bottom though. It will not mount near the gas block.
How are the handstops that direct attach to the forearm. I wanted something more low profile. I have a rail section mounted and Troy modular grip mounted to it. I have it in stubby mode. It works good but like I said I want something low profile.
