I am thinking of ordering parts and building my own upper, just for the experience. Has anyone else done this? If so, can you point me to any good bench references or manuals? My search so far has come up empty.

Mostlikely the upper build invloves in barrel and forearm installation. Check ARFCOM, there are BIY step by step write out.:)

If you go to Midway USA Shooting Supplies, look for the link to AR15 schematics. Click on that link then look for the link-Build the Ultimate AR-15 Varmint Rifle. It has a detailed upper assembly described with photos. Good luck. Nile.

Nothing beats the the US Army technical manual for clear basic instructions. I prefer the hard copy since it can be read anywhere.

Torque the barrel nut to 30 ft/lbs, loosen and retorque a total of 3 times before torquing to a position where the gas tube can pass freely into the receiver. Don't exceed 80 ft/lbs and definitely don't exceed 100 ft/lbs.

You only need the field headspace gauge.

Of the seven uppers I currently own, only two were assembled by the manufacturer: one Colt and one Bushmaster. The other five I assembled myself.

I used this guide to build my uppers:

I've built one. It's not all that hard. Check AR15.com and look in the build it yourself forum.

Personally I think it's easier than putting together a lower.

Actually it is. The only "hard part" is getting the rail aligned with the upper. But then that also depends on the rail.

I'm glad to see I am not the only one that bolted a heavy vice to a folding work bench :D

Hey Ted,

Is this (http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=351792) the manual you are referring to?

Thanks!

Yes, USGI TMs are good start. Download them HERE (http://www.biggerhammer.net/manuals/).:D

Thats a great solution for $19. I got a black and Decker workmate that folds flat and has a flip out piece at the bottom so that it can also be used for a hand truck. I drilled holes in the top so I can mount a big vice on it with bolts and wingnuts when I want to work on the rifle. It felt a little unstable when I was muscling off the barrel nut on my upper though, but not too bad. I've got to get a bigger garage one of these days so I can get a better workbench.

There's always one of these:

Yes. I have one and I've used it a few times for builds.

Another method is to use a detachable carry handle, scope riser rail or a scope in Picatinny spec rails to bridge the receiver and top rail of the handguard.

Thanks! Yes. That price isn't too bad. I've seen them go for as high as $20 at gunshows. You can download them, but it's harder to read in the bathroom during a morning "constitutional" or at your workbench.

Page 3-39 through 3-45 pertain to barrel installation. It makes the Arfcom web page look wordy.

There's some select fire specific information in the manual's lower related sections, but a reasonable person can extrapolate the procedures for semi-auto only from the text and pictures.

Getting an action block from Brownell's to put the upper receiver in the vice is probably a good idea if you want to install the barrel yourself.

You can get them at www.brownells.com

I got mine from Bravo Company cause Brownell's was out at the time.

I built one of my upper from raw parts. The barrel came with the barrel extension already on. It's really easy. I used AR15 as my guide. Some AR punches, a hammer, a barrel wrench, a torque wrench, a vice, and receiver vice holder is all you need.

Barrel extensions will always come installed, unless you're tackling making your own barrel from a blank: turning the profile, reaming your own chamber, threading for a barrel extension, installing the barrel extension, drilling the alignment pin hole and then drilling the gas port.

Where do you guys shop for this stuff to build your own upper. I was looking through RRA and it was cheaper to buy it already built than to build the same exact upper from parts.

I wish to build my upper the way I want it, but so far it looks like its cheaper to get one already put together and then mod it to your liking later.

Most interesting problem, was getting the barrels with a A2 front site already on the barrel. Didnt find any without it. If you want the barrel you get the site installed.

Any sage advice out there about shopping for parts?

My first AR was a complete upper/lower build, and I have since built two more. Maybe I did not save anything (probably spent more in 'upgrades' like a better trigger, rails...) but I ended up with something that is 'me', it's what I wanted. And it was not hard. A good workbench, vise and action block, barrel wrench and anti-seize/moly grease are the tools needed. I also used a torque wrench, as much as a 'cheater bar' as a measurement device. I only had the stickies at ar15.com to guide me (and a little madness ;) ). I have since found an old Navy M16 manual and that I find is a good source of troubleshooting info.

As for shops:
Ranier arms, Adco, Tenpercent, Global Tactical (GTS), Bravo, CMMG, Bushmaster, Del-Ton, JP and Brownells are all guilty of taking all my money. :D And they are all tops in my book.
