I just put together my lower this evening and I have only two parts left to complete, both roll pins. Strange that from what Ive read everything else was a piece of cake. Not what I expected. I didnt have a tool for that front take down pin assembly, but I didnt need it, took me about 10 seconds to do it, I did think about it for about 5 minutes before attempting it, just wanted to be sure how I was going to do it and not let the spring go flying to lord-knows-where. I didnt expect the roll pins to be a challenge, and Ive been wondering all night what to do in the absence of any punches, and I see the suggestion about the vice grips shall be my salvation. Thanks for that little tip!
I also have to agree on the addiction of this hobby. I think its much more enjoyable to build your own rifle. I get more satisfaction out of knowing what goes into the rifle as well as what comes out of it. [:D]
