I just built my first lower from scratch and I have a question regarding the hammer. This is a spikes enhanced LPK in a DPMS lower. The hammer is super stiff to the point where it will sit halfway between cocked and fired. When I fire it (without letting it strike the lower) it seems weak. Should I assume that this is a symptom of a brand new assembly and just lube it up and try and break it in, or is there a bigger problem? Mechanically everything seems ok. I can cock the hammer and pull the trigger. It just doesn't seem loose enough to strike with much force. Thanks.
