| Searched, couldn't' find anything. Tried taking the gas block off my DelTon upper to replace it and can't get the pins out, first i tried tap a tap a tap with a little sissie hammer, than a 16 oz claw and finally a 4 lb mallet. tried various punches and even heated up the gas block to no avail.I measured the heads first to make sure I was trying to get them out in the right direction. I don't' have a hydraulic press or i would of tried it, any tips/tricks? I didn't peen the head over before any body asks. |

BCM had an article about getting the pins out. I had a hell of a time getting some Sabre pins out of a FSB. Support the FSB with a block of wood and place it on concrete. Use a very large punch and big hammer. Get a friend to help hold it. Whack it to get it started, then used smaller punch to finish. |

Just did mine - Del-ton 16" lightweight with A2 FSB. I will tell you what I did, but you may screw the pooch and hit something vital. I take no blame in the below items:
I have the Brownells orange rifle block with the pins in/out. It must be SOLID like they are saying....Did I say that it needs to be SOLID...It needs to be SOLID. I used a #5 punch (Big), and beat it like it owned me money with an 8 oz ballpeen hammer - 3-4 good whacks...I mean whacks, and I felt the pins budge. I then progressed to the #3 punch...I think that is what it was to drive the pins all the way out took about 10-15 more good taps. They put a lot of oil on the pins, and they get a suction type lock when beat in. Oh, pay attention to the amount of pin sticking out so that when you put them back in...It's in the same place - Pins sticking out the same, Don't be afraid, and whack the thing. RobF |

Wood block on sturdy surface, 4lb Estwing drilling hammer, 1/4" steel punch to get the pin moving, then a smaller punch and smaller hammer to knock it out. |
