The only Cleaner/Lubricant/Protectant that should be used on the AR15/M16 family of rifles. It is documented in the technical manuals, listed at the top of this thread. Breakfree CLP is a popular brand of CLP and available anywhere gun cleaning supplies are sold.

For those who didn't read it on page 1 of this thread.....

There is no need to tag this post. It is tacked at the top of the Build It Yourself forums, and always will be there. It will fall out of your "My Active Topics" quickly so tagging it just adds noise to the thread.


If there is a problem with the pictures or anything with the post - please email me - keep the thread to technical discussion, to cut out the noise.

hey, can I ask another maybe dumb question? What do you mean by "tag"?

Although I haven't ordered a single part for my build yet due to continuing research, I have a question:

I have read this post and all other info I could find here about assembling my own upper, but I do not see instructions on assembling the actual receiver (charging handle, bolt carrier etc). Is this just too idiot-proof to talk about or was it left out because it is not recommended to assemble this yourself?

An A3 flat-top upper is pretty damn simple. An A2 rear sight assembly can be a little tricky, but no more than assembling a lower. I have had several requests to post this how-to.... but to be honest, I always buy my upper receivers complete... because you really dont save a dime by ordering these stripped. I have been meaning to order a stripped A2 adn A3 upper to post this.... but just never get around to it. If someone wants to send me their parts, I will assemble them for free and use them for the guide.

I keep seeing the "How do I mark the safe/fire on my lower?" come up and thought I would add some info on how to do this. I'm not suggesting that one method is better than any of the others. I personally use the lacquer-stiks and have no experience with the other methods. YMMV.

Typically safe is marked white and fire red on "military" weapons that have them marked at all. HK being the typical example. Here are some methods that can be used to do this.

Make sure you clean and degrease the safe/fire grooves thoughly before making any treatment on the marking for best adhesion and best results.

1. Crayons/Grease pencils. This done by rubbing the crayon/grease pencil across the cuts in the lower until they are filled flush with surface. I have seen mention of using Blue Wonder Armadillo as a protectant over this treatment. Make sure you rub the filling in well with a clean cloth and remove any surface film around the markings for the cleanest look. Apparently Crayola crayons are the best since they are proofed and heat tested while brand x is not.

2. Testors model paint. I mention testors since its readily available and used by a number people. Using a tooth pick or pointed artist brush fill the marking with paint. This may require more than one coat depending upon the desired results and your skill. Clean up can be done with a clean cloth and solvent after paint is throughly dry.

3. Lacquer-stiks. These are available from Brownells and come in red, white, gold, silver and black. You can obtain them elsewhere I'm sure. I mention Brownells because I know they have them and keep them in stock. Once you have removed the dried crust they resemble a soft crayon and are used the same as in method 1. The lacquer-stiks differ from crayon/grease pencil as it hardens and becomes permanent.

I have seen (can't find the pic) an assembly tool which appears to be a block that goes inside the UPPER receiver and is retained with two pins. Bottom goes into a vise. I don't know if this is a barrel assembly tool or not; saw it in an M.S.T.N. photo but cannot find it.

Is this a barrel assembly tool?

That is a different type of action block.... made by DPMS. I dont own this style... dont really see the point. Probably required if you use a non-standard upper receiver (like DPMS makes)

I wondered about it because someone (you) had to modify your receiver block in order to install a LaRue forend (not enough clearance up front). This would seem to solve the problem of taking the dremel out...;) I will try it and see.

Very very helpful and useful thread, btw - thank you.

I bought the DPMS "CLAW" from PK last week at a show. I've heard both good and bad about it, just like everything. I haven't had the op to use it yet, still waiting on a price drop on a CMMG barrel! The first one he tried to sell me was deformed like it had been dropped so I'm kind of courious to it's durability.

What have you heard that's bad about it?

I have a gunshow old USGI combo wrench; while it is the correct tool to remove the 3-prong flash suppressor I have, it is decidedly not the correct tool to use to remove a c. 1964 Colt barrel that's tight tight tight. I think I'm getting the SEI wrench; Brownell's, here we come!

I completed my first lower assembly following these instructions. It came out great. I am 3/4 finished with my AR15. I am working on the upper right now. I am waiting for my bolt carrier assembly and forward assist. I assume they are just as easy to install as the lower parts were.

One little tip on installing a match trigger, specifically a RRA, when you go to install the hammer push a punch through the hole in the reciever and then latch the hammer over the disconnector before installing the pin. I personally had trouble with the hammer binding and not letting me push the pin through without latching it on the disconnector.

I would like to say Thank You for the incredible instructions. I have been wanting to change out my own barrels and never had the guts to do it until I read your thread.
My only question is:
If my front sight is off to one side,
is it bad to have to losen up the barrel a couple of times to correct it?
Does it do any damage to anything?

No problem. It happens, especially canting to the left just a bit when you torque the barrel nut down.

This is listed in the Q&A on the first page:


Q5. "I installed my barrel, but my FSB seems canted in one direction, and in order to zero, I had to move my rear sight all the way to one side, and sometimes it still wont zero because I ran out of windage"

A5. This is a direct quote from Homo_Erectus on the issue:



--------------------------------------------------------------------------------
This is a very common problem with a very easy fix. It's caused by small differences between the upper receiver notch and barrel pin. And here's how you fix it:

Unscrew the barrel nut. With the barrel in the upper receiver, check the sight alignment by eyeballing it. If it's canted to one side, try and twist the barrel in the upper. If it won't move far enough, then take a jeweler's file and very carefully file the side of the upper receiver notch to open it up until the front sight can sit up straight.

Before reinstalling the barrel nut, you have to tighten up the receiver notch so the barrel won't move around while you're cranking down on the nut. With the barrel in the receiver, take a small hammer and punch and very lightly peen down the loose side of the notch. Careful, tap lightly because it doesn't take much. What you'll see is a slight flattening of the threasd right next to the barrel pin. That's it!

This really easy, and doesn't entail doing anything to the FSB.

Just a quick question, as I'm about to get into this soon. Under "Install your own free-float rail system, step by step:" you remove the front sight base, but it does not show how the front handguard cap is attached or how to remove it. Is it attached to the FSB, or is it just captured in place between the FSB and the barrel?

By the way, What a great post!!! Thanx!!!

The front handguard cap is captured between the FSB and a shoulder in the barrel. Remove the FSB, the handguard cap just slips off behind it.

Thanks for the great instructions. I thought that changing a barrel was beyond my abilities, but it turns out that it's not.

If your new barrel comes with the delta ring, spring, and snap-ring already installed, then you don't need to purchase snap ring pliers and can skip step 8. I had purchased the snap ring pliers before I figured this out, but I ended up needing them to work on my kitchen sink. I guess that sometimes things just have a way of working out.

On the first page:


Common Q&A:

Q2. What about the toquing three times, to 80ft/lbs like the TM says?

A2. While using a torque wrench is never a bad idea, it is not required. Snug it up, a few times if it feels rough, then line up with next gas tube hole.... sometime this will take a lot of force, sometimes just a little. If you arent sure, or nervous, go to the local auto parts store and borrow a torque wrench for ft. pounds.



The benefit of the torque wrench is just to make sure you are at the minimum spec, before checking your gas tube alignment. I just get it good and snug, then check. It has to go to the next gas tube notch. Sometimes this will mean just a little bit more, and sometime, if you have a long way to go, it will be very tight to get there, often beyond the max torque. Since you HAVE to get it alinged, overtorquing is not really an issue. The biggest problem is.... if people are overtorquing to begin with.... say they apply 50lbs, then check. If it would have lined up perfectly at 40 lbs, they should have stopped.

Since my elbow "clicks" at 30lbs, I dont need one.

Hi,

Faralak, thanks to this step-bystep I'm almost complete with my Lower build. I've run into a small problem though. The Bolt Catch Spring seems to have gotten stuck in the Bolt Catch Plunger hole and I can't get it out. The Hole is in Spec because the Plunger comes out freely but the Spring is jammed in there. Any tips or ideas on how to get it out? With the Spring stuck in there it basically renders my Bolt Catch useless since there is no rebound in the Bolt Catch. Any thoughts would be greatly appreciated. Thanks.

All you *need* is a 4" vise to get a grip on the action block.... but speaking as an individual who has broken a cast iron vise, I am a firm believer your vise can never be too big.
