those are tapered pins. they only come out one way.
Once you figure out the proper direction, get out your soldering torch and heat n beat. |

The pins are surprising sometimes. What I usually see when someone can not get them out is they think they are hitting the pins hard enough when they aren't. Using a trim hammer and a punch is not enough sometimes. Get the sight supported so you can focus on controlling the punch and a small sledge hammer. Give the punch a good swing with a sledge hammer and they will pop right out.
Take whatever amount of hammer force you think should be plenty and double it. Pretend your trying to drive a 16 penny nail into a 4x4 with one swing. |

Support the FSB in a special hockey puck and wail on it.

When I remove them, I make sure they are on concrete and I use a cupped punch and a 4 pound hammer and I hit them fast and sharp to get them started, once started they come out very easy, but you have to break that initial hold the taper hold has on them. When I was working in the Armories in the service, we used the biggest hammer we had and a plate of steel to back it up and we didn't hit them with kid gloves, we beat the shit out of them.

Are you going adjustable gas block? If not just shave the FSB. They are tapered pins they only come out one way. The best way to get them out is a torch, a punch and a BFH.

A taper pin punch (cupped punch) helps as well. I've also used a piece of oversized steel round stock (7/16") instead of a punch to break them free. As mentioned, once the initial hold is broken, they come out very easily. |

A piece of 3/4" brass round bar coupled with a BFH will pop them loose without fucking up your FSB.

Ya pretty much what was mentioned was what we had gone wrong on. We were hitting it on a wooden bench with play and I was concerned about doing damage to the barrel so I wasnt really giving it a forceful blow. So now I'm gonna go put it on concrete, and start hitting it until it gives

Good punch. Good whack.
A real penetrating oil may help too, wd40 is for drying out distributor caps ;) |

Well boys. I have bad news to report. After a couple more hours of effort, and nearly bending my upper I have realized that the delta ring will not be going down without a fight. And as fun as it was to get this far the proper tools will be required to continue.
Without an upper vice block I'm afraid of doing some permanent damage so I'm just gonna let a smith knock the ring off and pay him his fee. I do have one request for Palmetto State Armory. Stop using these guys to install parts.

In the future go to Home Depot and buy yourself a mini sledge hammer. It should be less than $20.

Are you saying you just chucked the upper in a vise and tried to wrench on it? Good news is I took it in today, paid 30 bucks and got it installed. I also bought a upper and lower vice block while I was in there because I have no doubt that this is the first of many builds and might as well have the right tools. Now all I need is a torque wrench and I'm set to go. Still a long way from being done, but its now back in action. Still working out which muzzle break I want to use, and what optic I'm going to put on. Eventually I would like to get a RAS rail but I have several other guns that I'm working on at the moment and its going to take a back seat to those for now.

If you have a large bench vise, just use a corner to press out the FSB pins to where they are loose, then tap them out the rest of the way. Also use it to press the pins back in. Takes all the effort of of it.
