It allows for precise installation or removal of muzzle devices, barrel nuts, and other components. The upper receiver can be indexed on the reaction rod for assembling the ejection port door and forward assist as well.

For those who don’t already know, you CANNOT do better than Marvin’s barrels. Or pretty much anything Marvin makes. Spend some money, buy his stuff, own great sh*t.
Quality item. Machine work is flawless. Best HK barrel you can find brand new.
Great hard to find unmarked HK upper. Super fast shipping too!
No issues with installation. Was easy to just, just took a little time to try the different jets. You need to make a version for the MR762.
It is nice to do business with a company that provides impeccable customer service along with quality products. Very happy with my purchase of the HK 416 reaction rod.
