I was surprised the dealer made an issue of it too. I guess he isn't familiar with Colt carriers during the ban years (like me!)
I have yet to do it, but before I get a new carrier, I think I will try to re-stake my gas key. I might change my gas tube out also since the gun has so many rounds through it.
I'm familiar with the companies you mentioned and have done business with Bravo Co. before. If it comes to a new carrier and key, I'll do just that.
Thanks for the advice
