I honestly don't know, It depends on how much the upper receiver is damaged. I might be able to slip a small piece of barrel shim material on the sides of the alinement pin? But now I don't know whats better for tightening barrels on, reaction rods or vice blocks.
I have a Magpul Bev block and a vice block for AR15's and prefer the Bev block, but for the AR10 I'm not sure whats better.
I don’t think putting 35-45 ft lbs, on a barrel nut, using a reaction rod, should cause any damage.
MRA appears to have good Customer Service, so have they offered to replace the Upper?

I would think not.
pin loose or not if you damage your upper you were doing something wrong.
Ya,maybe.
Not sure how the damage could have got there.
But it sure looks like it had something to do with the pin.
Would it have something to do with tightening and loosening the barrel? To get proper to get proper thread break-in?
If I did something wrong I don't know what it was, I installed the barrel nut and muzzle break to the manufactures specs. I don't hold Maple Ridge responsible for the damage to the receiver only because I'm not a certified gunsmith, I installed it and take full responsibility to any damage that occurred. I really don't know what could have loosened the alinement pin like that or caused the flaking of the nickel boron plating. I'm still waiting for a reply to my emails.

Sorry I didn't mean that in a rude way either. But it looks like torque was transferred through the pin and it shouldn't be during install or removal. The index pin is for alignment and care should be taken to lessen torque acting on the pin.
I like the BEV block or reaction rod but I take care to try and keep the upper from pressing into the pin when torque is applied to the barrel nut.
But I am sure everyone has their way of doing things and people will say that's not required but I like to play it safe.
As far as the pin coming loose or the NiB flaking I don't know. Maybe the hole or pin was out of spec or it came loose under torque and maybe something went wrong with the coating. Stuff happens and it looks like they are looking after you.
Mistakes happen, we're are all human, it's how things are handled that counts. And it looks like you are in good hands.

No worries, I'm just a bit worried that my emails have still not been answered yet. I still don't know if it's better to use a reaction rod or vise block when installing the barrel.
I've done some research online about reaction rods and vise blocks and found that some index pins can actually shear off with enough force when using reaction rods. I have put a lot more torque on an AR-15 nut while trying to index it with no damage, but I was using a clam shell style vise block. I also looked at the engagement of my reaction rod with the barrel extension and believe that it's the cause of the nickle boron to flake.
Maple Ridge Arms have contacted me and want me to send them my upper receiver along with the barrel, gas block, muzzle brake, handguard and reaction rod. I think they will probably come to the same conclusion about the reaction rod. I will post the results of their investigation when I get it.

Updates?

We have received the barrel and upon inspection we have determined that the pin was loosened during installation and not a result of manufacturing. We are repairing the barrel free of charge as a customer service gesture. We will have the barrel returned by early next week.

Good to hear. Someone else just posted in another thread saying their extension pin is also loose ... Is it better to not use ant reaction rod type of tool to install the barrel nut?

The second post has said the index pin is loose but also that the BCL102 receiver is larger than the pin. There have been cases with other barrels where the barrel was torqued and the steel index pin crushed the 6061 BCL102 receivers resulting in a loose fitment. We are still investigating this matter. We have not determined anything at this time.
In this thread, the index pin came loose during installation, not during manufacture.
We use reaction rods without issue. The reaction rod holds the barrel extension in place. If too much torque is applied to the barrel when using a reaction rod, the barrel can rotate free of the barrel extension, loosening the index pin since the pin is punched into the OD chamber threads. Since the barrel extensions are torqued on to 140 ft/lbs, the force required to free the barrel from the extension would need to be greater than this.
Another way the index pin can come loose is if the hand guard being used required the use of supplied barrel nut shims to properly lock the barrel into the receiver. If the shims were not used, the barrel was not properly seated in the receiver. In this way, the barrel can move freely and the steel index pin can crush into the receiver. In this way, the index pin would be pulled free of the barrel extension due to the receiver prying one side of the index pin free.
If you dont over torque your muzzle device and ensure the hand guard barrel nut has securely locked the barrel into the receiver, you shouldnt have any issues with your barrel just like the other 4,000 + customers who use MRA barrels.
