A2 Front Site Removal

[jtischauser]

I was trying to remove an A2 front site last night and it won. Anybody have an insider tip in how to get those pins to budge? I felt like I wasnt getting good support under the site which may be my problem.

they're taper pins & come out the side that the cases eject from the upper

They can be a ***** sometimes.

That was going to be step 3.

Roll punch and big hammer. I usually have to make the first hit hard, then it taps out after that

Most of them come out one way, but some are opposite...depends on mfg.

Bring it over Jesse. I can get it out.

If you have a sight block, it will help. All I have seen come out one way.

Mine were so bad, I mushroomed two punches getting them out. I would wail on it for about 20-30 minutes and quit when I got so mad I was afraid I was going to smash the gun. I did that 3 or 4 times before I finally broke them loose.

Since you all don't like my humor.....Try putting some heat on it with a propane torch. A hole will expand more than the pin thats in the hole. Seriously.

Once I knew what direction to push one swift hammer got em both. Now the barrel nut was another thing. I ruined one of my wrenches and had to cut the delta ring off with my Dremel and use a pipe wrench on the stripped barrel nut cogs. This is a brand new upper too. I guess I may not be torquing my builds this tight?

 

[Wall]

I don't torque mine to any set spec. I just get it tight then turn it 1 more hole to line up for the gas tube.

 

[jtischauser]

Is that last turn a *****? I was within a half of a hole when it was pretty tight so I just went a half hole more. Think i should go for one more?

As u can tell I'm a newbie when it comes to building uppers and lowers for that matter.

Tight as you can go by hand then spin it to the next hole.
