Come September ( with any luck ) I plan on putting a flash suppressor on a pair of bushie ar's. the question is does the front sight block need to be removed in order to turn the barrel? I have access to a metal shop and a metal lathe but dont want to have to take the FSB off of it ( since I most likely not line it up correctly on reinstall.I have heard that bushmaster finishes the barrel and fsb as one piece and dont come off easy.)
specs ( correct me if I am wrong )
barrel end turned to .505"
5/8" length of turn
1/2 x 28 tpi
seporate upper and lower reciever
remove grips
remove gas tube pin from fsb
remove gas tube
remove upper reciever from barrel
remove delta ring
turn and thread
put all back to one piece
will headspace be effected by the barrel removal and reinstall?
if I am lazy how much is it to have a smith perform the task?
thanks in advance
