It is NEVER a good idea to swap bolts around. Ever owners manual ever produced will tell you so. The military manuals offer a sever warning with an ugly skull and cross bones/Mr. Yuck cross logo to make sure each and every dip-s**t soldier understands this.
T2, even if those parts are you call them are made correctly, and to print, there is still the chance that you could have short or deep headspace. Check the prints for the parts and look at the +/- variances on the bolt and barrel extension as well as chamber. Do the math.
It is not worth the risk. Just buy another bolt and carrier and be done with it. Consider it a one time $100 life insurance policy.
