So to begin, yes I used the search function didnt come across anything helpful. So I am upgrading from a junk polymer lower to a forged anderson mfg. My issue is the rear of my trigger assembly is to high to allow the safety selector to slide in. I tried pushing it down with a punch had no movement. I then dissasembled and reassembled with safety in first. Once together I am not able to release the hammer or put safety on. Deffinitly a tolerence issue. Everythjng is assembled correctly. Is my trigger out of spec or is the hammer out causing it to push to far down on the front of the trigger. There is a lot of wear on the hammer on the rounded bottom. Keep in mind I did pull this assembly out of a polymer lower which worked perfect. I even reassembled the polymer lower and it works fine. Please throw in your opinion before I start blindly ordering parts
