For those of you with functioning Arc Fire triggers in your AR15s, what uppers and lowers work without modification? My Colt definitely won’t work. I have a Sharps Livewire sitting around that doesn’t look like it would work. I’d hoped to find a BCM blem stripped lower since I’ll cerakote anyway, but looks like they’re only sold as complete lowers. I was hoping maybe a stripped Geissele? If so I’d prefer to get a matched receiver set. So what has been functional as a drop in for you guys?
