I was soo excited to come back home!
I had a PSA armors set waiting for me (the molds and the armorers wrench) a PSA 10.5 upper, a KX3 Flaming Pig, and a DD Rail (the one that works with the A2 front site post) Sooooo I started getting everything ready, and I'm at the point where I have to remove the A-2 front site from my AR and BOOOOM the pins won't budge. I've been all over the internet looking for direction, and I'm thiiiiis close to dremeling them out. I've already broke 3 steel punches. Can anyone give me advice on what to do? I'm desperate here. I've made sure I was using a nice sturdy work bench (also tried concrete floor), I'm hitting them left to right (according to which side the pin head is largest), Should I call this a loss, start drinking, and just buy some sort of Brownells tool to do this? Pictures of my shame below.

Did you try tapping the other side?

They are taper pins and you are driving them from the wrong side

Soak the area generously with break free and let sit, get a punch that isn't soft, tape off around the pins, use some blocks of wood to support things better. They will go eventually. Add some heat if necessary and repeat.

Take a torch to it heat it up- and try tapping from the other side.
Those pins are ruined - drill wouldn't be bad. Get it hot and flip her over :) |

ETA: thats why your punches are soft. They break so the pins stay the same, I doubt the pins are ruined. |

Op, if the side you're bashing is smaller than the side you're not, then you're good. Grab a larger punch (once you have the head of the pin started, then you can use a pin-diameter size), and pound away. I've had a couple through the shop that I have literally beat the dog shit out of, but eventually gave after my thinking they wouldn't. Just grab a larger punch with more surface area and get them flush.

1. Take a decent caliper and measure the diameter of both sides to find the small end. Then drive from the small side.
2. Use a much larger punch to start with until they begin to move. I usually use a 1/4" diameter punch to get them started, then it switch to a smaller punch. 3. The suggestion of soaking them with penetrating oil first is a good idea. I always do that. |

Do the first two here. I have had to do this on a few PSA barrels. They are tight as hell even when driving from the right side. They will move though. Change to the smaller punch once they move. |

My Colt came out from the other side. You should be able to visually discern that one side is bigger than the other, tap the smaller side. Which will be the ejection side.

I mean back it up by supporting the sight base really well.
I've had to put them in a Kurt mill vise and build a support for it a couple times. Otherwise they bounce too much. The way your punch is peened makes me think there's too many timid hits.

FYI, the folks are arguing over the Sea-tac 15$ minimum wage law so for the sanctity of peace of mind I might be better just working on AR stuff all day. Since I have you all here, are there some cool stuff I can buy so I don't have to deal with this problem in the future? This is my 4th AR (first with an A2 front sight) and I have 2 more coming from PSA with A2's in them. What tools do you recommend? Brownells looks like they had some good stuff |

Looks like PSA taper pins are the same as Colt's and BCM's. I learned the hard way that you can't use a punches and hammer on these taper pins, so after spending a lot of money on punches and destroying FSB's, my dad, who is a machinist/mechanical engineer by trade, made a aluminum plate to fit different AR barrels, a assorted set of punches, and installed a chuck to hold the punches on our hydraulic press. Now my taper pins come off without damaging the taper pins or marring the finish on my FSB.

Definitely the wrong side. Use a good punch of 1/4" or BIGGER just to start them. Put it on a concrete floor and back it up. This plan works every single time for me. Use a good heavy hammer, and hit it like you mean it. The concrete floor will not give or bounce, and helps a bunch. The bigger punch makes it so damn much easier to start them, then use the smaller punch to drive them through |

FYI liquid wrench did not do the trick (let it soak for a bit)
Again for all you "use the right tool folks" feel free to add the link and I'm happy to buy them. I honestly thought that with the Vice blocks, amorers wrench, and a decent set of punches I'd be able to add a rail and a F/H to this bad boy but apparently not. Folks are about to eat dinner so I need to make nice so I get some delicious Turkey and additional shots of the fancy rum. Thanks for all the advice guys. FYI: Briefly tried hitting the other side, I'm 100% sure (after a couple drinks) that I'm hitting the right side (not literally but right as in you're wrong) due to the fact the heads are noticeably larger on the side I haven't hit much. If I'm wrong on this and I've been hitting the wrong side this whole time, not only will I admit it in this thread but I'll buy a membership for a 2013'er on GD (I know I don't have one myself but with the feedback I don't feel I need to renew like I used to) |

I was soo excited to come back home! I had a PSA armors set waiting for me (the molds and the armorers wrench) a PSA 10.5 upper, a KX3 Flaming Pig, and a DD Rail (the one that works with the A2 front site post) Sooooo I started getting everything ready, and I'm at the point where I have to remove the A-2 front site from my AR and BOOOOM the pins won't budge. I've been all over the internet looking for direction, and I'm thiiiiis close to dremeling them out. I've already broke 3 steel punches. Can anyone give me advice on what to do? I'm desperate here. I've made sure I was using a nice sturdy work bench (also tried concrete floor), I'm hitting them left to right (according to which side the pin head is largest), Should I call this a loss, start drinking, and just buy some sort of Brownells tool to do this? Pictures of my shame below. http://i214.photobucket.com/albums/cc33/weckerm/Punch_zps752c8cd3.jpg http://i214.photobucket.com/albums/cc33/weckerm/A2_zpsd3dc429b.jpg This look like the large side of the pins. Any pins that I have encountered, the tip of the small diameter end of the pin is smaller than the hole diameter the in FSB and the pins sit much lower in the hole. |
