Whats involved in removing the front sight and adding a low profile gas block on a AR.
Is it just a matter of removing the roll pins?
I just dont want to dick up my Barrel while removing or installing.
Is there any tips to doing this project?
Thanks k9

Filter through this thread. Most barrels have FSBs held on with taper pins, some have straight pins and I have see a few with roll pins. I don't have a problem with this, but some do.
