Why are these damn things so hard to remove??

I feel I have beaten these pins like they owed me money or something and I still can't get them to budge. I've used a torch to heat the FSB, I have soaked them in penetrating fluid, NOTHING.

What do I have to do to get these damned pins out? I am cutting down the FSB to go under a full length rail.

Hammer and punch and a very solid bench vise so all your energy gets transferred to the pins.

This is generally the process. If memory serves, some pins are tapered, so there is a specific in/out direction. It's debatable if you need the bench-block though. You could probably skate by w/ just some wood.

Get a taper pin punch to avoid flattening the heads. If they flatten, they will make a mess coming out, or never come out.

I froze my upper to get them out.

A 4 pound sledge got mine out! And no, I am not kidding! This was after I flattened them and had to grind down the part that I flattened. I was wondering if I was going to bend the barrel!

Watching those brownell videos and seeing him lightly tap them out is pissing me off! Time for a bigger hammer.

VICTORY!


I had to put the upper on a concrete floor covered by a rug and then I beat on the pin with a heavy brass hammer directly onto the pin (no punch). Once the pin recessed a bit I was able to go to the punch. I had to beat the hand guard mount flat to get to the rear pin the same way. After that they came out easy. I had the FSB resting on a piece of 1x4 with a hole drilled in it so the pin could go down into it.

What a pain in the ass.

WOW, sounds like a lot of work for something that could have just been cut off on the barrel & sanded smooth to look nice. That was gonna be my suggestion, til I got to your last post.

Here is what all the trouble was for....




No before pics, no during pics, just the after.

I cut down the front sight base, which came out really good. That is the Troy MRF 13.5" rail. Good stuff. Now just a few hundred more dollars in parts and it will be as tacticool as possible.
