IRL, this thing needs a set of optics, but I wouldn't recommend them for Receiver. I'm putting a 4x optic on mine, and that's just too much for Receiver and wouldn't fit well anyways. I would stick with the back up iron sights built on. The rear one folds down, btw

Not too powerful for Receiver and the non-military version doesn't have full auto, so it wouldn't be too OP.
If you do decide to do this guy, I'd be happy to work on some models for you, get reference photos of mine and make some videos of the operating mechanics up close.
