Tolerance stack is tolerance stack.
First off don't borrow trouble. Get your part, put it in the gun and see if it looks ok.
Do the tape test. Measure your rim thickness. Measure your tape buildup thickness.
Check the total: .060 Min vs. .070 Max. (

IN FACT you can check your old bolt while you are waiting for the new one to come in. Remember most tape compresses a little. Your measurement may or may not be what the gun actually is closing on. You may get different results with and without the ejector in place.
Now about that tolerance stack up...
The bolts should be 'the same' but there will be some slight variation acceptable in the manufacturing.
Assuming a CNC manufacturing mill and assuming that it is set up correctly and run correctly
(proper material used, material jigged consistently, cutters measured for wear in between runs so the machine compensates for decreased length/diameter, worn out cutters resharpened/replaced in a timely fashion, temperature maintained within a certain range for the facility during production runs, machine calibration verified and maintained on schedule, the machine operator doesn't 'tweak' feeds and speeds outside acceptable parameters, finished product acceptance checks in place and maintained, any post machining operations like deburring, finishing and so forth don't change dimensions, etc..)
Now assume the same parameters for all the other machined parts that interface with those parts and may cause additional tolerance stack: (Locking lugs, Lug raceways in the receiver, exact fit of the barrel to the receiver.
Although there are a number of factors that come into play among the parts, IF the design is correctly blueprinted AND the manufacturing is done correctly then the parts should fit together without additional adjustment being required. It is also possible that the design can be done in such a way that minimal manual adjustment is part of the assembly process. There may be a feature of one or more parts that is designed for some fitting that is considered necessary and required to make everything come out right.
If there's a problem what next?
From the standpoint of the factory they may have a bad part or a bad batch of parts. They might swap them out, send them back, destroy them or modify them so they are in spec depending on the cost to do so and whether or not they can be made safe to work. They are going to want to fix the problem that is causing the problem though because merely fixing the part or assembly in question is more work.
If there's a problem with your gun it can be more involved and potentially more expensive.
That is why Missionary is putting O rings on his ammo rather than having someone disassemble the gun and put either a new barrel on it or modifying the barrel so it can be turned 360 degrees deeper in the receiver, having the chamber end shaved off, recutting the extractor groove, and feed ramp or other features, refitting the barrel bands, forend, etc..
Again don't borrow trouble. Wait and see.
