Assuming we are talking about a standard factory installed mil-spec AR-15 front sight base, this is incorrect, the pins ARE tapered and must come out from a specific direction. A roll pin punch, with the projecting tip, is not the right tool for the job, and will be immediately ruined if used thus. They are solid taper pins, not roll pins, and closer to 1/8" at the small end.I'm going to assume we are talking an AR, take a 1/16" roll pin punch supporting the barrel and sight solidly, tap them out doesn't matter from which side as the pin's aren't tapered.
The part about solid support, such as a steel bench block, is quite important. I have had to apply gentle heat and penetrating oil to get some of these pins loose, they are often in there tightly enough to damage a Starrett pin punch.They do bisect the barrel which will have two channels cut in it. You will then need to remove the flash hider and muscle the base off. You will find that under it the barrel is not parked, are you replacing it with something different? You really don’t need any heat just patients. Good luck! And remember support!
I want to remove my front site base. I had 1 guy take a stab at it, and it didn't even budge. Doe anybody know a local smith that could take care of this for me? I'm trying to gte it done by this Friday for the group shoot.
Thanks.
