Help, trying to remove my front site base so I can pull the barrel and I cannot for the life of me get these pins to budge. I have tried to get them out from both sides and they will not budge. What am I doing wrong. And I have done this before, although it has been awhile. TIA. |

I just removed the ones on my 601 barrel, hitting the pins from the left to right. It took a while to get them broke loose, it is a 40yr old barrel after all, but they eventually came out. Just keep trying. BTW, why are you taking the FSB off to pull the barrel? Free float tube? |
Nope, I am changing out the upper. Building a retro 605. |
I want to build one of those too.  Don't happen to have a spare receiver do you?  Or are you gonna use one of NDS's when they come out?ETA: Still not sure why your taking the FSB off to change a barrel. Unless you have a early barrel with a gas tube that has the early bend to it. Then I can see taking the FSB off. |
Got one before they ran out. Been collecting for awhile. Course mine will have a 16" barrel, no SBR's in MI! And not worth the $200 to hack off 1.5", I am not going for totally correct, just the look. |
OK... I just went through this for the first time. One came out very easy indeed... lots of support in all the right places.... wack and out she came.. didn't have to use a heavy hammer either. The second was a very different story, I did mushroom the pin. Had to use a dremmel to grind it flat and start again. My problem was not having good solid support, was lucky the first came out like it did. Eventually got a block of wood and fashioned a FSB block. You can get the from brownells, if I could see myself doing a few of these I probably would get one. That said the home made job worked fine. Left to right as you look down the barrel. Good luck...I was going insane over the second pin, you would have thought I won a gold medal when it came free.

Why not use a standard slabside upper? The 605 came out in both the standard slabside (604) and the "modified" 603 uppers. |

| It is stuck, try some Kroil. I haven't used it on the AR, but it sure works on some of the other stuck pins I have tried. |
Well that is not too easy when the gas tube is in the way, but I will try to get the gas tube out of the way without ruining it, it seems pretty stuck in the gas block. |
