I think you're full of it and now giving the "I'm really a good costomer" routine to try and save some face. But that's just my impression. Sounds like you've wasted a bunch of employee's time.
While I agree that CSC and every other gunsmith has every right to turn away customers looking for free advice or information to reverse engineer a tool, I also think the prices they charge for a simple IUR barrel change is out of line with the work involved. OP -Ditch the IUR and stick with a standard, good quality floated AR.
As an aside, I once brought in a stripped Swiss Arms upper and the original barrel for a change (no disassembly, sight swapping or reassembly of the upper was required -just a straight barrel swap). I fully expected to be charged the 1 hour flat rate for the 10 minute job, and left butt-hurt when they had the gall to charge 1.5 hours and shop supplies to boot. First and last time their gunsmith gets my business.
That doesn't actually even show the pin I'm wondering about, very odd.
If you look at the pic, on the upper just above (as shown in the pic, not where they are installed) item 17, you'll see a small hole on the receiver side. Is there a pin in there? What's the purpose of that hole? Very odd it's not on the parts list
I'd say #10 goes in that hole, it may be a way to insure the barrel nut won't back off the receiver.
What if their reply was:
"Sure we can absolutely show and tell you how to do that, lets see when our gunsmith is free. Our rates for seminars and courses are 100$\hour 1 hour minimum. How will you be paying sir?"
Would that have been better?
Yea, actually, it would have been. I wouldn't mind paying a good gunsmith for an hour of his time to get some expert advice. Hell, I'd probably pay him for two or three hours of his time! To be able to sit down and learn from someone who's done it for years, maybe even see some examples of what he would be talking about doing... yup, I'd have taken them up on that.
Didn't expect that answer....I presume?
First of all I apologize for not having seen this sooner.
With respect to visiting the gunsmith, he does not have slow times. He and his assistant each work 40+ hours per week. They are currently about 6 weeks behind on projects. Every day the staff at the front of the store do their best to deflect visit requests so that work can get completed. It just is not possible to book "chats".
We are sorry that he does not have time to sit and spend time giving advice to those that seek it, but it isn't his job and he truly does not have time. And this applies to members, customers and strangers alike.
It is unfortunate that you consider this disrespectful but we also have a duty to finish customer work in as timely a manner as possible.
Nice gun.
Could you please post a picture of the wrench as well?
