Ok, I have been toying around with the idea of getting an AR platform rifle for a little while now, So one day I was bored flipping through a Magzine and I saw a M16A1 kit. Originally, I was aiming for one with a rail system, but I know a normal forend, (Or Triangle one in this case) would suit me better, and also porbbaly bring my dad back a few years... (He was a US Army Sapper in the Early '70s Luckily, Never saw action though) So after a bit of thinking/planning/schemeing I've found the parts I need to complete the kit, But I have run into a few headaches, and I know you guys are expirenced in this kind of stuff so, Please forgive my inexpirence in the following qestions. ----First of all, This is the kit I found,M16A1 Kit, Sportsmans Guide Does anyone know of any problems with this kit? ----Second, I was reading through the parts list and it includes everything but the Trigger Disconnector. My question is, With a Trigger Disconnector installed will this convert it from Full-Auto to Semi-auto? Or will I have to buy a whole new internal parts kit for the lower? ----Third, It says that A-the barrel doesnt have grooves drilled for the sight, and that B-the barrel is Unfinished. A- Would drilling the grooves require speicalized tools? Or would a hobby gunsmith be able to drill the grooves? I have a teacher that is a hobby gunsmith and I know hes good at doing stuff like this, but If it requires speical machines. He may not be able to do it. Luckily I know I could buy a Gas block with a rail system and Mount a Detachable front sight to it if speical machinery/skills are required. B- Would a Finishing Spray such as Brownells AlumaHyde,Be a viable solution to this problem? Now, I will ask what you think about the overall Idea of a 15 Year old doing something like this, do you think I am getting way over my head? or that this is possible if I have acess to the right resources? I have researched all laws and regs for it and I know I cannot own the Lower reciever, but I think my Mom wouldnt mind (If I do attempt this, Im trying to keep my dad in the dark till Im done), and I have several FFL Dealers that I know wouldnt mind transfering it. If you see anything I missed please let me know, I know this sounds like a complex thing for a kid, and it is all still a BIG Maybe, and the feed back I recieve will probbaly be the final deciding factor for me. Thank You, Josh P.S. I do have the means to support this, I knew it would cost some major $$$. I have some work lined up so if I do decide to go for it, I'll have a head start. Once again Thanks.
