Is it possible to convert the Russian caliber 5.45x39 riffle into NATO caliber 5.56x45
Which major parts need to change if possible
Or its impossible to use any parts or receiver of 5.45x39 riffle for 5.56x45

Looking from answers from experts and gunsmiths

Well, if reaper ever comes along I'm sure he would be able to tell you. My unprofessional opinions is, you would probably have to change out the barrel because of the head spacing issues. The lower you can still use, and even the upper would probably still work, but the the nato is longer and therefore it wouldn't chamber correctly.
