I'm not trying to build a super secret gun, I've recently started going to the shooting range this past year and just fell in love with everything GUNS. Started doing some research and found out about 80% receivers and parts kits and would love to build my own as I like building things. I've read a couple times that it's not illegal to build your own firearm as long as your allowed to possess firearms, at first I thought that just meant no felony convictions, but now that I've asked around a bit it's starting to sound like I need to have an LTC to build my own firearms. I was caught with class A twice in my early twenties and as I've mentioned both cases were CWOF and I got probation both times. I am however currently trying to figure out my best option of going about getting my LTC, if it's even possible. I was trying to get my LTC some 10 or more years ago, I did the safety course and received the certificate, I have two references, I was right about there then the CWOF's happened. Now at present time, I would like to try again but will definitely have to do the course over again, as I'm sure I can't use a 15 year old safety course certificate (I think I heard somewhere 2 years is the oldest, anything beyond that I would have to retake the course). So I am looking into getting my LTC right now, I've even recently contacted Jason Guida to see what my options were, but, in the meantime I was trying to figure out the legalities of building your own firearm because I wanted to make sure that I wouldn't be doing anything illegal if I took an 80% receiver and parts kit approach but now that you guys told me what's what, I'm just going to try and get my LTC first. I appreciate all the help and advice as I DO NOT want to end up like that kid serving an 18 month sentence in that link that was provided. Thanks
