I posted this as a reply in another thread, but figured I'd post here for (possibly) more exposure.
I've put a Nordic +2 on my SuperNova and I've already put a Mesa PG stock and Nordic follower on it. There are plenty of US made 922r replacement parts for the M4/M2/etc, but I've never really seen anything for the SuperNova like hammer, trigger, etc. Assuming I need to swap out one more part on mine to make it compliant, does anyone have a source for something else I can use?
Additionally, does anyone know if the trigger/hammer out of the M4 is interchangable with the pump guns? Looking at them, they look almost identical (at least the hammer).
