different A2 upper, swapped bolt, and headspacing

A while back I bought an A2 upper w/o bolt carrier. Then last year I bought another AR but with an A1 upper. So I took the bolt carrier out and put into the A2, then put that onto the lower receiver. Since I sort of swapped parts here should I be worried about the headspace at all? I can't remember how much I've shot it since I bought it but I do know I shot 2 rds though it during hunting season with no problems.

    Don't worry about it, they are interchangeable like all US Army small arms parts. If they weren't, they would be serial numbered to the gun they were fitted to. The only parts not interchangeable on the AR are front sight housings and stripped barrels. Barrels have to be fitted to their particular barrel extensions.
