Do I really need the special tools described in this video to assemble my lower? http://www.brownells.com/aspx/NS/GunTech/NewsletterArchive.aspx?x=v&p=0&t=1&i=1112

I have tools for mechanical work that are quite extensive, except the specialty ones described here.

No. It makes it easier if you do. I built my lowers with a small hammer, and needle nose pliers.

Good punches do help. If you try to "wing it" with screwdrivers and such, you risk scratching the receiver, which would piss you off, I'm sure...

If you go to Harbor Freight and pick up a set of punches it will save you from that frustration...

You can do with less, but the tools listed are pretty basic.

A good set of roll pin punches and starter punches will help you not mar the finish on your lower. other than that a soft faced hammer is about all you should really need. Another thing that is nice to have is one of the plastic blocks that goes in the mag well from the top down, as it keeps the hammer from ever falling on the lower, and possibly cracking it.

i think you will prob. need the multi tool as well to attach the buffer tube.

Agreed, punches help - but you can get by without them.

Might I also suggest a hard, plastic mallet as opposed to the "framing hammer" that is shown in this picture? :eek:

Have plenty of punches, drift and roll pin punches.

Have a plenty of plastic hammers.

You can tighten the nut on the carbine tube with a hammer and punch, though the special wrench is much easier.

get a cheap punch set, 10-30$ max works great.
yes everyone bashes cheaper than dirt, but i got my punch set for 25$ or so. works fine with a mini hammer.

Not really - just swear a little more, it's free. ;)

Agreed! The wrench is shown in the later photos and is cheap enough to be worth buying. I got mine from riflegear.com in person for around $6.

I actually have that wrench, but my upper is already assembled by Stag.

If you want some help just come by the shop in Costa Mesa (Sat or evenings during the week are best). I can get the roll pins and pivot pin in for you scratch-free, and then you can do the rest yourself pretty easily.

No "Special" tools are really needed just an eye towards improvisation and don't be ham-fisted.

Needle nose pliers

masking tape

pin punches

Small (I mean small) ball peen hammer

several soft towels

Small block of wood (2 X 2 X 1/2)

Word of advise...when installing pins and springs be in a small, well lighted room. This makes finding the spring when it flies out unexpectedly, easier to find. In addition, save the beers till after the lpk is installed (I speak from experience).

Here is another source of info that might be useful..

I don't want to say its easy and have you go and try and screw it up, but I did it in about 20 minutes with a small hammer, piece of plywood, needlenose pliers, and duct tape. I've never built an AR lower before and honest to goodness it took less than half an hour. It's not hard. I recommend having a friend over to watch while you do it, makes it half as likely to miss things.

Masking tape,a 16oz sheet metal hammer, a couple of small nails, a Leatherman tool and an old plastic stock for an SKS are all the tools I used for building my lower.

I've built the past 9 with a hammer and leatherman and spanner wrench.
no special tools are needed.

I assembled my AR with no special tools and didn't screw anything up....nor did I scratch my receiver. :)

roll pin punches are the most essential thing you need here. standard punches work, but may deform the pins from the impact. an armorers wrench is good as well, because it allows you to tighten the castle nut and barrel nut if necessary.

as far as using the whole vise grip method to push pins in, i prefer using pins and a hammer.

a nice trick i have found, for installing the front pivot pin detent, is to use a flat blade or similar flat piece of plastic to wedge and keep the spring down, so you can drop the detent and slide the pin over it. this is the trickiest part of installation! because the spring will catapault the detent across the room if you arent careful :)

another good trick is to use a dry cleaners suit bag when you install the lower. put all the pieces inside and assemble it looking through the bag. that way if anything flies out you wont necessarily lose it

I like to use a small rubber strap wrench

works good for me...

I'd say get a castle nut wrench or the DPMS multi tool. Its a solid piece of equipment that I just got from ADDAX and its awesome. Other than that, I didn't use a hammer at all, just a cheap 5 dollar punch from harbor freight. I will say though, that the punch put a tiny tiny little scratch in the receiver from me not being cautious and not taping the receiver when it came to the bolt catch pin. It was a gnurled edge on my punch and just brushed it ever so slightly.

This is the punch, its a spring assisted center punch that you can change the tension on: http://i95.photobucket.com/albums/l122/bombadillo08/punch.gif

dont worry, many builds have some kind of dimple around the bolt catch pin/hole. another reason to use roll pin punches though. they are round at the tip so they dont deform the pin, but also they keep it from sliding off and damaging your receiver.
