Anyone done this yet?

It looks straight forward, I have the upper stripped (screwed up and didn't realize the barrel had to be out before trying to punch out the dust cover pin, damaged the front pin, live and learn there).

My concern here is that there is what looks like a roll pin, under the gas tube, right over the barrel extension. What is this for? Looking in the hole it doesn't look right, almost like it's not a roll pin. I'll be making a barrel wrench shortly for this barrel nut, so I'll just need a rain rod and the barrel should be off? Or do I have to get that cross pin out? Or is it even a cross pin?

Does anyone have the armourer's manual for this gun?

You need the tool from Colt Canada to remove an IUR's barrel. The pin you're speaking of is the barrel extension's alignment pin (barrel indexing pin), that fits into a notch in the upper receiver, that keeps your barrel aligned. Do not damage or break this pin.

Nope I don't mean that pin - i'll take a pic tonight and post it. The pin I'm talking about goes through the upper receiver between the top of the barrel extension and the bottom of the gas tube. it looks like a roll pin sort of. if you look at the top of the rail, you can see a cutout where you can look down and see the pin going across from one side of the receiver to the other.

as for the special tool... i'll be making one, that's fine. i'm curious if there is anything special I need to know to pull the barrel, or do i just stick the reaction rod in the bolt lugs, and the barrel nut wrench in that end, and unscrew the barrel nut? any pins that would stop the barrel nut from rotating?
 
Yea I'm going to stop by there and see if I can talk to the gunsmith. I can't justify paying someone to do what I can do very easily. If all it takes is a special barrel nut wrench, that's pretty darn easy to build on a mill or lathe. I just want to make sure that little roll pin looking thing isn't going to cause me issues.
 
Yea, I just went in to Calgary shooting center to ask their gunsmith for advice. Instead of even talking to me at all, I was told "sorry we don't help people, we're a business if you want to have the barrel changed we will do it, but if you want to just get advice or see what the tool we used looks like you won't get that".

F that. I wouldn't pay them to do it now no matter what. On principle, I'll use the upper as a baseball bat before I pay them.

ok the gunsmith shop has a $100 / hr shop time. Did you offer to pay the 1/2 hour or min shoprate to talk to the gunsmith? Or did you just want to disrupt him working on paying customers guns so you could learn how not to use their service? Shops do not need "customers" like that.
I'll leave it at this... For now.

If you manage to make a proper tool, you should start changing the barrels of people who have IURs and charge a lower rate than gun stores. :p

Bingo. Same crap happens at our shop.

I have NO problem with a gunsmith wanting to be paid for his work or his time. Absolutely.

It was more about the way I was treated than the fact he didn't want to come out to talk.

To say "Sorry, we don't help people here" rather than "He's busy with customer's stuff, and can't come out and give up time he'd be working on customer's guns" is part of what erked me.

But we all know it would have been a 2 minute conversation, if that. It's called customer service. I've *NEVER* been to a gun store or gunsmith before that would refuse to offer some friendly advice to a customer - especially one who is regularly there spending money.

Not to mention the fact that I was there to spend money. I was in there to buy a reaction rod, an action vice, some furniture, and even potentially a new barrel and a new upper and lower receiver. I simply expect decent customer service. If he's too busy, no worries, I can come back when he's free to chat for 2 minutes. Not a problem at all.

So if they don't need "customers" like that... that's fine. I'm happy to go to one of the many other gun stores that DO need "customers" like that ("that" being people who like to do their own work, but spend goodly sums of money buying parts and tools from them, and occasionally wanting to get an expert opinion on a small task that's being worked on.... horrible I know).
 
And to all you guys who appear to be poopy about me "wanting to take away his time without paying"... asking 2 minutes for a quick piece of advice when I'm in there to spend hundreds of dollars is hardly the same as coming in regularly to leech hours of time from the gunsmith without ever spending a dollar.

Customer service has limits. I agree. Coming in to simply ask for advice, then leaving to spend money elsewhere on the parts/tools, that would bother me too. But coming in to buy tools, and asking for a bit of advice on how to use them exactly... I don't see an issue. Heck, I even told the guy "if it ends up that it's not a tool I can make, I might just get you guys to make me one".

At the end of the day, any business has the right to do what they want. But I expect a certain modicum of customer service as a PAYING customer. I know The Shooting Edge gunsmith is happy to chat with me whenever I've wanted to - usually just to shoot the sh*t, but the few times I've asked for a "professional opinion", he's had no problem giving his thoughts. Again, customer service.
 
Any particular reason you want to dismantle a perfectly good Colt Upper. You may be better of building a Mil Spec upper with the barrel length you are looking for.

Wow that's a great idea... I bet it could work for just about any enterprise in fact we should apply this principle to government.
Can't imagine what it would be like to improve service at a lower price.

Just a thought...maybe you should've bought the stuff first and showed you were a paying customer before asking for freebies. At times, information and knowledge is the most expensive product a business has to sell and many would be reluctant to just give that away. Sometimes you have to give a little before you get a little...

Yea, I am actually only dismantling it because the PO had painted it, but the paint used wasn't very durable, so it started rubbing off, especially when cleaning solutions came into contact with it. It started looking less than nice, so I decided to strip it of all it's paint. I got all of the exterior surfaces done, but the barrel and heat shield are proving next to impossible.

I may get it cerakoted, we'll see, but for now I'd like to bring it back to it's factory finish, and the only way I can think of to do that is to have the barrel out of the upper so I can properly scrub it and the inside of the handguard.

It wasn't the first, second, third, or tenth time I was in there.

But no, I personally don't agree. It's about customer service for me. I can go over to The Shooting Edge, or down to Proline Shooters, or out to Alberta Tactical Rifle Supply, walk in, and ask the gunsmith or one of the gunsmiths a few questions, and there's no issue at all. If they're busy, they say so, and I have no issue with it. If it's a complicated topic they can't answer in a couple minutes, I won't even ask the question because I do have a lot of respect for the value of their time. But to simply shut me down wholesale, I wasn't impressed.

Don't get me wrong, I fully support capitalism, and I fully support the ability of a private business to make their own choices about who they help and why they help and when they help. I also support my ability to not be impressed by the lack of customer service.

Part of the problem, to me, couldn't be seen without being there. A lot of my "unimpressed-ness" comes from the shirk attitude I received, not from the actual refusal to give advice. I know I'm not "owed" a reason, but from a business standpoint, it's generally much better to give a customer a reason for not providing friendly advice than it is to outright refuse to do so.

But yes, I've given a lot. At the end of the day, I shouldn't need to buy something just because I want advice - I gone there regularly for purchases, but to think that each employee needs to witness me spending hundreds of dollars before they are willing to offer advice - that's a non starter.
