Im just surprised the ATF hasn't ran after FN in a back alley grabbed them and butt fucked them into submission yet..If he had went through with a conversion using the parts he had he would have been subject to the 10 year 250,000.00 fine. From what I understand you still have to do a bit more work then just installing the gen 1 hammers . I believe somewhere there’s a blind pin you have to remove and a spring?? I’m honestly not 100% sure as we never had a post - sample P90 at the shop (unfortunately) but that was my understanding and the gen 1 / gen 2 trigger packs had some of the parts and the capabilities to be modded. It’s crazy because they’re on Gen 4 trigger packs right now still trying to find that Goldilocks zone of ATF approval lol
