Nice. The color difference doesn't bother me so much (though I might have a different opinion if it were mine, lol).

What barrel is it?

What option would you do? As for the barrel, I'm not sure.

Norell's is what I'm guessing most would suggest.

Maybe try scuffing the lower up a bit and go the battlefield pickup route.....

I was thinking that also but couldn't figure what to use to do it?

What was the oal barrel length, on an m16a2 carbine?
Link Posted: 7/27/2016 10:36:12 PM EDT

14.5".

An M16A2 carbine has an A1 style upper on it btw. Colt did odd things.

Interesting. I have a question about the forward assist, on my upper. It's round except for a flat side, toward the receiver. I haven't seen one like this before. Can anyone shed some light on this?

Also, the front sight is F marked. When I assembled my a2 rifle, the barrel had an F marked sight and I had to almost burry the post, to get it sighted in. Will I run into the same issue with this build?

F marked is fine for a carbine, and incorrect for a rifle.

I talked to the guy I got the barrel from and he got it from someone else. He asked that guy because he got the upper assembly from him and turns out it's a BCI barrel.

Looks good to me.  More importantly, how does she shoot ?

If she shoots straight, a little paint job on the lower to match the upper and it's perfect.

If you want to go that far.

Just assembled the upper last night. I still need to get the fsb pins in all the way. I'll pop some rounds out of it this weekend.

It looks awesome as is.  I can see why that might bug you, but really, who cares if it shoots well.  If it's a clone gun, it happens with them too.  The color differences I mean.

Or there is always this:






I can't decide if I like that I painted mine or not.  But everyone is doing it, so........

So what do you guys think of cutting the barrel to 14.5" and getting the longer flash hider? Other than ascetics, would it really gain anything in the build? If I was gonna do it correctly, I'd SBR the thing.
Link Posted: 7/29/2016 2:38:48 PM EDT
[#16]
I'm kind of like Meh on the whole thing.  Yours looks good the way it is.  Sometimes that little bit makes for a bit better handling gun, maybe.  And the dwell time is a little bit less which is probably a good thing.  And yeah, it just looks more legit.  It's just a matter of what you're willing to do for the sake of cloneliness.  For some reason I sometimes actually like the way the 16" M4 looks.  Other times I think it looks too long.  I have no clue why.  The extra velocity is an upside to leaving it.  But not sure how much it is.  Some say that 1.5" makes a bigger difference in velocity than other lengths.

I think the cheapy CAR stock without the two vertical things on the underside of the curve bugs me more.

Hope I did this right and the pics post. I used steel wool on the black Anderson lower and used a sharpening stone on the high spots, to give it a "field look". How's it look?

The large round head forward assist was used originally on the Model 723s. They utilized A1 upper and A1 lower receivers. Later, some of the large round head forward assist were used on A2 uppers. Some of these upper were uses with A1 and A2 lower receivers. While they worked well with A1 lowers, they had an issue with the A2 lowers in that they were not the same profile as the A1. In light of that, part of the forward assist had to be cut away in order for it to operate with the A2 lower. That is why you will see a D shaped large round head forward assist every once in a while. The large round head forward assist was eventually replaced with the small round head forward assist because it did not require any modification to work with the A2 lower receiver.

Good job lightening that lower to match the upper.  Personally, the nitrided barrel bugs the crap out of me more so than the color difference between upper and lower

I dulled it down a bit also. After the pics were taken, of course.

The ones I've seen marketed by Colt as M16A2 carbines used A1/C7 type uppers. Model 723 as seen in this Colt advertisement.

These were the initial A2 models. The Model 727 was made during the transition to the M4. The XM4 was being developed at that time as well. Additionally, some of the early Model 723s still had A1 upper receivers and late Model 723s had M4 profile barrels.

I will say this, wasn't the 727a .mil only thing?  I didn't think they sold it commercially.

Now it has optics! Aimpoint 3000 with Colt mount. I filled in the Anderson logo and sanded it smooth. Next step is to have it cerakoated Saturday to match the Colt upper. Would the barrel be the same color of gray?

How did you fill in the Anderson logo? Pic?
Link Posted: 8/3/2016 7:49:01 PM EDT
[#31]
I scratched the anodized material, from the logo. I then used rubbing alcohol to clean the material and made sure it was dry. I used a bit of quick steel and forced it into the logo parts. After it hardened, I took 350 grit wet/dry sandpaper and smoothed the entire area out. I then used 500 wet/dry to fine tune it. I'll post an after pic of the cerakoat job but here's a before.

Yes, yes it does.  Good job.  You gonna do something about that stock....  Something about those handguards look wonky too.  But I'm nitpicking.    We need a range report!!!!!!!

Looking really nice with that 3000 on there.
Can,t wait to see the photos after she's refinished.
Still trying to find a Aimpoint 5000 for mine. A 3000 would even be nice.
I keep missing them when they come up.

The M16A2 "family" was entirely commercial/export models, including the R0727.  

Colt used the "M16A2" designation to refer to far more than the 20" military M16A2 (U.S. RIFLE, 5.56MM, M16A2).  

The commercial/export M16A2 family was select-fire, and production started prior to 1986, i.e., they were most certainly sold commercially, and even available to interested civilians for a time.  

Their primary market was, of course, domestic law enforcement and agency sales as well as export, e.g., the "Abu Dhabi Carbine."  

They were never officially "adopted" by the U.S. military in the same sense as an "M" or "MK/MOD" designated weapon, and rather were known by their commercial designations and purchased "Commercial Off The Shelf" (COTS) for use by the military.  The Navy referred to the R0727 as the "Model 727" (not "M727," which is some airsofter bullshit), and they were colloquially most commonly known as "CAR-15s" based on their similarity to the XM177-family which many users were already familiar with (though the term was not even totally correct when applied to XM177 family, either).

Very nice. Mine should be done shortly. There was a four week backup, at the place I'm getting it cerakoated. Worth the wait, as they are the best in our region, at cerakoat.
Link Posted: 9/9/2016 9:29:41 PM EDT
[#40]
OK. The cerakoat went well but not so much on the logo. I filled the logo and sanded everything flat. When they put the lower in the oven, the crap I used came out and its almost as pronounced as before. Next will be paint or just leaving it alone.

I still need one more piece to the puzzle. I need an M9 bayonet. I have a current USMC Okc3s bayonet that I'd trade for, if someone wants to.

F marked sight towers are taller than unmarked ones for comparability with detachable carry handles. Anytime you mate an upper with integral sights to an F marked sight tower, you'll have that problem.

Now I guess I need to find the correct Surefire flashlight and mount, for a sort of BHD weapon. Any suggestions?

So I have a few more questions, for you guys. First, any idea where to find the Surefire flashlight with mount, to complete my build? Second, is it correct to have the side sling barrel mount on this weapon? Was it used during that time? I carried an a2 rifle with a 203 on it and if I remember correctly, my sling was through the fsb. Was there a date when these things were used?
