Posted: 4/24/2015 4:14:09 PM EDT
I'm a bit lost here, and need some help before I contact the GunBroker seller.

I purchased a retro 20" pencil barrel assembly, but think it may be a replica barrel for non-firing models.

The pins wouldn't budge at all, so I decided just to carefully grind the front sight base off. What I found is "odd", to say the least. It appears the pins are fake. I ground one pin off and found there's no pin at all going through the front sight base. The metal is "formed" somehow to look like a pin, but it is not. The entire sight base and right into the barrel itself is actually a solid piece of metal! Meaning, the sight base is actually fixed onto the barrel, or appears that way, and the "pins" don't really exist.

I believe the seller gave me a replica barrel, maybe something used to build non-firing "wall hangers" or replicas that sit on a display stand on a desk.

I've attached pictures for some help. The first picture shows one of the pins ground off, so you can compare to the pin next to it. As you can see, there's no separate pin going through the sight - the front sight base is all one, solid block of metal. You can also see in the first picture that, after grinding into the barrel just a bit, it too is part of a single piece of metal with the sight base. Although they look like separate parts, this is one, formed/cast piece of metal shaped to look like a real "real" barrel. The second picture shows the other side with one of the pins ground off for comparison, where you can again clearly see there's no pin going through the front sight.

Does anyone here see otherwise? Anyone ever see this before? Thoughts?

Moose,
The pins are tapered and will only remove from one direction. when they didn't budge, you should have tried hitting from the other side. From your pics, the pin is clearly visible under your grind marks. There appears to be carbon in the gastube hole as well.
Pic's of the chamber, and bore would confirm that you do have a real barrel. You should see rifling inside as well.
Keep us posted,

The second picture, you can see the transition material difference between the gas block and the pin.

Appears to be a real barrel to me.  THe taper pins are tough sometimes.  Set the barrel on a hard wood block and use a good hollow nosed pin punch.  I think they remove left to right, but it has been years since I have had to take off a FSB.  Just curious.  Why were you removing the FSB?

If you have a pair of calipers you can measure the pins. The left side of the pin, as looking from the rear, should be about .125 or so. The right side, as looking from the rear, will be about .140- .146 or so.   You drive the pin out from left to right. Some are VERY VERY VERY VERY hard to knock out.
   I don't know what you would hope to gain by contacting the seller, in my opinion.  Personally, I think you were a little quick to break out the cut-off wheel/die grinder.
How do you suppose that front handguard cap was installed if the sight/barrel WAS actually one piece.........which it isn't.
Edit:  you weren't too careful in your grinding.......you've ground into the barrel on the one side.  I hate to sound like an ass and give you a hard way to go, but geez man, think the process through a little before doing irreparable damage.

This is my thought too, along with the aforementioned grinding damage to the actual barrel itself.

OP your barrel looks fine/legit to me. Can i ask why were you trying to take the FSB off in the first place? Did you think it was a replica before this process?

In all seriousness, I zoomed in and it looks like a very worn MP between the FSB legs.

Moose - first, welcome to the forum.  

Second - if this is the worst problem you run into, you will be fine.  John Thomas is a master at rebuilding stuff.  He can patch that up with a new FSB and get it back in shape so don't sweat it too bad!

Also, great resources here to access BEFORE getting a bigger hammer (or grinder as the case may be) so ask lots of questions next time.  And if you get into retro builds, there WILL be a next time!

From what I can see that's a real barrel. The pin for the FSB is visible the ground up area in pic #2. Another giveaway that it's not all one piece is the rust creep coming from in-between the FSB and barrel.

The tapered pins can sometimes be tight and are only come out one way. An easy way to remember which way they come out is that they come out on the same side that the brass comes out.

Looking at the pictures I'm guessing you were aiming to replace the handguard cap?

I thought that was the case, too - meaning, I thought I could see the pins in the grind marks, especially in the picture. Unfortunately, the circles on the grinded portion do not line up with the pins on the other side, so much so that the circles couldn't be the pins. That's what's driving me crazy :)

I came real close to bidding on that one

JT is awesome and will get things back up and running in no time, for a very reasonable price Im sure. Good luck in your future retro builds, and even though your welcome was a bit lacking on our collective parts, we are a pretty helpful bunch usually. The tacked threads at the top along with www.retroblackrifle.com are excellent resources. Good luck.

Moose, Sorry the welcome was pulled in on you. Most people here are very mature and most helpful.

Good luck. And stay civil.

Combine that with a first post and minds begin to wander. I am glad you got hooked up with JT, he has treated me very well in the past. Good luck, and welcome if its not too late.

I sold that seller a CMPB barrel last year. I thought that might be it, but I had it reparked..By JT of course.

Lesson to be learned here kinda like "Measure Twice Cut Once" ....

is "ASK FIRST.......and PUT THE GRINDING WHEEL AWAY!!!!".

The only reason most guys wigged out is we search high and low everyday for RETRO parts, and we cringe seeing original parts getting hacked. Don't be offended, like they said it is just an expensive lesson.

Good luck Bro and JT will definitely take care of you.
