I have a Colt SP1 mfg in 1971.
Suggestions for removing the bird cage suppressor.
It is on very tight.
Thanks for your help.

    You could try sweating it off by gentle application of heat or freezing the barrel assembly overnight or a combination of both if it's stubborn.

    One bit of caution here. Don't use a wrench on the flash hider w/o holding the barrel itself. Don't use the receiver for leverage.

    Heat and penetrating oil. Might be on with thread sealer or even worse epoxy.

    Thanks,
    Never considered heat or freezing it.

    You might also have a crush fit washer between the base of the FH and the barrel. This also applies pressure to keep the device in place. Heating will help quite a bit if there's any loctite on the threads.

    Don't know if I did it properly or just got lucky, but I bolted my barrel in a vise at the front sight assembly. Not alot of pressure, just wanted to keep the assembly from turning. The FH came off very easily.

    That front sight/gas vent is only held by a very small roll pin. You got lucky.

    Sent mine back to Bushmater as my gas tube was bent and I could not sight in Properly. Think that it may have been the previous owner trying just what you are.

    Heck, well it's about time the bread landed butter side up! IIRC, there are 2 solid pins left to right through the front sight base along the top of the barrel, which I assumed (incorrectly I guess) held the front sight to the barrel while that single cold rolled pin held the gas tube in place in the front sight. If the cold rolled pin holds the front sight in place on the barrel, what do the 2 solid pins do? ARs are a bit new to me, have built a few but still learning.

    The front sight base is mounted to the barrel with two tapered pins. That small roll pin up high on the FSB is the gas tube retaining pin.

    My mistake. Senior moment. Still not a good idea to use the front sight for leverage. While the pins are fairly stout, the sight base can be loosened doing this and lets your front sight wiggle. Even a very small amount will ruin accuracy.
