Atrius Forced Reset Selector (ADG-FRS-S) and FRS Lever Standalone (ADG-SP-LEV). Not compatible with a PSA lower receiver. If your 5.56 lower (this may work on an AR-10, IDK) does not have a pocket directly behind the safety selector switch like mine (see picture) it won't work. I have $259 tied up in these two items and Atrius won't let me return them. I will happily sell these two like-new items to you for $200 and mail them to you for free! Pick up in Noble or anywhere in Norman. I accept cash, Venmo or Cash App. Message me here or text me at REDACTED/p>

Or just make me a legitimate offer. Oh and it is recommended that you have an H2 buffer.
