AR Doctrines 101 Class

[alazgr8]

I am in no way an expert on AR's, and I hope I don't come across as a know-it-all, but I built 4 AR's (and I stayed in a Holiday Inn Express once) last year with my four sons. I bought complete uppers, so my comments regard the lowers only.

If you look on AR15.com you can find pretty explicit directions, and photo's. It would be a good idea to read as much as possible, and familiarize yourself with the lower reciever parts kit, as some of the springs look pretty similar.

Of the things that can go wrong and is probably the worst thing that can happen during the build is appying too much force on the rear ears of the lower reciever where the trigger guard goes. When you are driving the pin in, you could actually break an ear off.

When driving in the bolt catch pin, if you aren't careful or don't use masking or duct tape to protect the finish you could scratch the lower reciever. Don't ask me how I know. "Nuff said.

If you aren't familiar with the springs or don't use a photo that shows the spring/name you could install a spring in the wrong location, then you will have to drive out the pin that most likely retains the spring to get the springs in the right locations.

To me the most important tools to own are are a small hammer and roll pin punch's. Everything else you can probably borrow.

I think this is a great thing Bass is doing and I will be interested in his lesson on building the upper reciever.

Regards,

Rick

Upper vise block $49.95
Multi wrench tool $24.95

You can do it without those tools, but they make it easier. You will need a small hammer, set of pliers/channel locks, painters tape, some sort of punches, and a castle nut wrench. A vise can be a life saver, with or without the upper vise block.

Well considering that the last post was May of last year I don't think that this is going to happen.

This thread seems to be a bit played out, but I'm hoping to revive it. I've always wanted an AR, but it was not at the top of my priority list, so I don't have one yet. However, since land is banning the sale and import of AR's on 10/1, the necessity to build one rose to the top of my list. I just bought 2 Lower receivers which I have in my hand, and 2 parts kits, one of which I already installed. Pretty straight forward build, YouTube helps a lot.
But now I'm concentrating on gathering parts for the upper receiver and barrel assembly, and not sure exactly what I want, or how to do it. So many ways to build it, and so many different parts and manufacturers, it's a nightmare for a newbie to AR's.
I said I bought 2 lower receivers. I want one for short range rifle with a Red Dot sight, or EOT, or something, and the other I want for a long range rifle. If and when the SHTF, I want to be ready for whatever comes along.
Any takers in explaining, or helping me out, or anyone else with the same idea?

There's about any option, caliber, length, etcetcetc. BARREL has to be 16.1" min or you get to apply for stamp. Here's a link: http://www.ar15.com/forums/f_3/4_Build_It_Yourself.html

You will probably have to sign up for membership but there's also most of the mfgr's on this site too.

Goo luck, uppers are only a little more diff to build than a lower. Probably takes longer to figure out/find what you want

Ron, you can have a 14.5 inch barrel as long as the flash hider/comp is pinned to the barrel. That is what I have on mine.

Or a ten in with a six in flash hider.

Thanks for the info, guys. I just picked up my lower receivers, and while I save some money, I have time to decide how I want to build them. One will be for short range, and one for longer range. I''m just trying to do all my homework on what's available to help make my decision.

Yes I have one of those in 5.56/.223, but I also have a 10.5" & 14" not pinned barrels for SBR in 300 BLK and yes I have the stamp of approval from the BATF along with the lower engravings as required. I also have a suppressor for the 300 BLK with the stamp. The suppressor is removal, and not pinned.

I'm looking into a SBR and Suppressor myself.

Check out psa. http://palmettostatearmory.com/index.php/ you can get complete uppers if your wanting to. I have bought 3 or 4 from them. Plus they have a great deal on ten pmags and a lpk. I have two of my rifles topped with aimpoint comp m2's bought off ebay for decent prices.
