Just bought a new Colt M4 Carbine engraved lower and noticed something unusual when I got it home.

The line next to the mag release fence is raised to the point you can feel it when sliding finger over it and causes the line to be visible as in the photo. The inside of the magwel appears to be perfect and nothing else seems out of the ordinary.

This does not appear to be anything but a cosmetic issue so I'm gonna roll with it but thought I'd throw it out there to the group.

You can physically feel a variation where that line is?

That is nothing.
Colt has never really worried about cosmetics.

You should have seen the nasty looking crap they put out during the Clinton ban.

That doesn't seem right. I would contact Colt Customer Service and see what they say. https://www.colt.com/service/

I suppose that is better than the grinder marks.

It's just cosmetic and it's a NFA item so even if they replaced it I would be out another $200.

Serial # is CR8423**. Anyone have a close # to see if theirs have this issue?

Bet there was an issue with the die and serials close to this one have the same thing.

If everything else is fine and square… and that line is just a forging blem and not the result of something crushed/bent…
I wouldnt care too much.

Maybe it's a reinforced mag well since it's thicker.

As far as I can see everything is square and nothing is crushed or bent. That seam is the only thing noticeable telling me it's probably a forge die issue.

I'd be more disappointed in the casting voids present at the bottom of mag well.

I'd be more concerned with a purple color one

Not a casting, so not a casting void. It’s from the forging process.

Sent pictures to a guy that works for Colt and they stated the seam is due to the finishing process and is not a defect of any underlying structure.

Looks better than the line on my transferable lower.

It could be worse. I just came across this one on Gunbroker. Even with Colt doing Colt things, I'm surprised it made it out the door.

And you believe that is genuine, Gunbroker no less?

I'm a little skeptical, to say the least.

Who is shown as the Manufacturer on the Form 4?
That looks like it might be a weld up of two destroyed lowers that was done before the '86 cutoff date.  A number of Class 3/SOTs would buy batches of the lowers that the government had cut up.  Parts would be chosen so that a viable lower could be readily welded up from two parts.  John Norrell was the acknowledged master of such weldups.  So much so that the BATFE had some of his lowers x-rayed as they did not believe that they were, indeed, weldups.  I've never seen a weldup, but the typical weldups that I've seen in photos look similar to the posted photo.  On the other hand, When your making as many M16s as Colt did in the Vietnam era, almost anything will go out the door.

MHO, YMMV, etc.
