I would get a factory banded front, if you insist on a permanently attached rear peep - you could likely sneak a skinner low pro peep behind the rear ring and leave it in place but it would require a single #6-48 hole be drilled and tapped. However if you need to remove the scope anyways, is it hard to tighten a NECG rear peep on the ring seat? That way you don’t alter the receiver, have more adjustability and likely a stronger setup.
