Completed my lower last night after the gun show. Went ahead and picked up the KNS Mod-2 Gen-2 non-rotating trigger group pins and installed them. Bent one of them a little. Guess I torqued it down too far. This is my first build and I'm having a great time so far. Nothing like building a rifle! Went ahead and threw my FNP-9 in there..just because it's sexy.
