Hey guys. I was in a hurry trying to get my Lower receiver put together that other day because I might have a buyer for my DTI but I wanted to get my new kit build and tested before the sale and I accidentally put the wrong detent spring in with the front take down pin and I can't get the take down pin out for the life of me. Does anyone have any advise for me. I do have a extra lower parts kit in case I have to cannibalize something, hopefully not. Thanks for any help. Here are some pics of what I am talking about. This is the pin I can't get out. This is the pin and spring I used, I pulled them from my extra LPK.
