Hi,

Even though, Ive been a shooter for a couple of decades, including IPSC teams, owning few firearms, I have yet to build one.
That being said, please bear with me, for some silly sounding (to you) questions ;)

I am still working on building my AR platform based toy. I have so far:

1. M16 A1 Colt lower F/A
2. complete lower parts kit by FTF Industries
3. BCG (nickel boron), also by FTF
4. buffer tube by UTG pro
5. stock and grip by BCM
6. charging handle by BCM
and various tools, vise grips, etc.

Since I am not in a hurry, slowly learning and digesting the info, I still need to make a choice on upper, free float / hand guard, gas block, barrel.
To answer the main question: what are you planning to do with it? I'll be taking to the range, twice a
month, for some fun time and rarely some precision shooting (yes, scope will be added). Hence the idea of having 16" or 18" barrel.

Regarding the UPPER:  I was about to buy an Aero Precision M4E1 enhanced upper, then I thought of Larue or DD or JP Ent. Then I ran into gazillion others and got lost!

They all built out of 7075 alum, but the prices are from $69 to $400! AP advertise "enhanced upper". Is that a gimmick or something I should look into?

So, need an advice here please!

Thank you, best regards

I like the aero stuff. You can get a regular upper or the enhanced if you plan to use their handguard. The enhanced have the mounting part for the handguard already attached to the upper. Hope that makes sense.

Thank you for a prompt reply.  I am planning to instal MI hand guard or DD if more money will be available.
Do I need this "enhancement" added on AP upper?

thnx

UPD:  I just checked their site. Now I realize, that their enhanced upper is only suitable for theirs handguard! :)

I'm guessing that you do not want an A1upper receiver?

I would buy a Colt M4 upper, personally. Aero is not the quality that they were in the past, imo.

I never thought of A1 upper, nor do I want one.  About M4: I checked the gun broker and other sites, and it
looks like you can get one for $175 (shipping incl).  Not bad, but Aero is $79 bucks.  I do have that
extra $100 to spend, but trying to find an answer - why?  I mean, same material, same programmable,
computer operated milling machine, same anodizing.... What else?

Thank you

No offense, but you have a lower worth like $15k at least. It doesn't really make sense to put bargain priced parts in it like utg and FTF industries. Go out and buy some quality Colt parts

If you got a tax stamp lower, then it doesn't matter what barrel size upper you get so long as you keep in mind that you get a Full Auto bolt carrier group so that it trips the fun switch.

Since uppers are relatively inexpensive, I would go with a couple of different uppers like a 10.5, and 14.5 and just shoot the flavor of the day. I wouldn't really care about brands and chances are you won't be happy with one upper considering the amount of fun you'd have with a tax stamp lower.

Here's what I would buy:



I would start with this: Colt 14.5    <--- that would be my main upper

10.3 upper <-- fun day at the range


Personally I wouldn't use a tax stamp lower as a self-defense rifle as there's a chance the police won't give it back to you when they seal it as "evidence."

Brother if you bought a Colt M16A1 lower, putting a UTG buffer tube on it would be a sin. Buy a genuine Colt receiver extension (buffer tube) as well as F/A Colt LPK.

Thank you, I'll check the better stuff.  But when I was web surfing, FTF offered a FA BCG at a normal, $200 price. Not cheap, not expensive. So I bought it. About UTG, it's only a buffer tube, I was looking into BCM, but ordered UTG.  I am not a AR15 type of guy.  More of a pistol competition person ;)
Thnx for advice

Last 2 I bought had shitty machining gouges inside the upper. Clearly incompetent. Also the anodizing was patchy.

Cosmetic, but crappy and avoidable.

Fella,

A Colt F/A lower? Like most have said, you need to pitch all that cheap shit and start over again with all genuine Colt parts.

ETA: To do it justice, the upper should be all Colt too.

It's just not typical you see a person new to ar15's having an m16 lower at their disposal. It's also not typical for a person with a FA lower asking about the cheapest parts they can use to complete the rifle.

It's like a 16 year old who just got his license asking what the cheapest fuel he can put in his mint condition '67 mustang.

I would suggest having a gunsmith look at your build prior to firing it. I don't have anything full auto, but I have heard that poorly made parts can lead to an out of battery discharge if the timing isn't right. I would be much more trustful of Colt parts than questionable ftf industries. Colt fa parts can be had for less than the money you paid for the ftf parts if you shop around

Thank you for a proper advice.  Perhaps I have started on the wrong path, but.... I can explain the reason, I didn't just bought all the Colt or DD parts.
It would have not been a challenge, would it?   What's the point of "building" the rifle, if you just order one package with all the parts and assemble
it in two hours?

I might add, that the main parts, such as barrel, GB, etc, will be top of the line.  I did spent numerous hours and days, reading the form and other
media, and only here, I am hearing that FA BCG (nick.brn) by FTF, priced at $200 bucks, is crap! Yet, the Colt's FA BCG costs $160, BCM BCG - $170,
and most of the BCG that are sold by cheaper production companies, are run from $80 to $140 usd!

Is there some sort of an issue with FTF Ind, I should know about

And yes, most of you were right on the barrel issue. 14.5" it is.  But first, I must deal with the upper.  After being (slammed in the face) chastised
by all, I will get a Colt's upper.  Could you advise, if there is a difference on "C" + square or "C" + keyhole, or...?


Thank you,
Warmest regards

Keyhole = Cerro
Square = Brass Aluminum Forge Enterprise

Both are markings of the forge, both gtg.
The C will designate that the final machine work was performed by Colt.

Thank you.  By FN, you mean Fabrique Nationale? (if so, I didn't even knew, they were making those parts for AR)

Also, how come no one suggested JP Enterprise for example? or DD?  
BCM is what everyone talking about. Yet, BCM best tool is aggressive marketing and...yes, they do make a good
products!  I did actually ordered few BCM parts, but didn't know, the buffer tube (machined to mil-spec) was that
important...

In any event, I'll order Colt's upper.  And since I narrowed down to two choices for free floats (DD or MI), I assume,
it is safe to say, that .750 GB from DD is a right choice? Correct?

thx

Thank you, but I don't want to buy a fully assembled upper. That is a half of the rifle and I am trying to build one, piece by piece. Even if I'd want the same look (which I admit, looks excellent), I would still order every piece separately and try to assemble it myself.

Thank you.  I looked at DDM4 upper before. I admit, it looks great, but then I came to the conclusion, that the Colt's (grayish black) lower
and dark black DD upper with all the markings, will not have the perfect symbiosis.  Colt upper it is!

Now, it's free float, GB (no idea yet and I know nothing about them), then barrel or vice versa, then iron sights, then sights (inclining
towards  Trijicon for now, after scraping the idea of red dot, etc).

It's not that important. Most every upper today has m4 feedramps. Just make sure to get corresponding uppers and barrels. So ramped barrel + ramped upper or both non ramped. Don't mix them
