Roger makes the best little bits and boodles for ARs. I've had one of these for a while and it's too nice to just throw into any upper willy nilly. Forget the rest, go FCD. Also finally my fridge has some kind of magnet for decoration and it's a duck (my favorite constellation)
I love the milspec charging handle. Never had a problem with it. The extended charging handle on my M27 always snags on my kit, making a bunch of senseless noise (with which my autism has difficulty coping). FCD are the only manufacturer I've found making what is essentially an ambi milspec charging handle, and I want one.
