I have a Bushmaster carbine that I bought about 16 years ago and I knew nothing about AR rifles. It has the non removable carry handle. Now 16 years later I know about the same about ARs and would like to have my upper receiver swapped out to a flat top for mounting optics. How much would that run for labor and who could do it right? It appears that I can get a stripped receiver for about $90 if I look around. I am in no hurry. Thanks in advance, Murphy.
