question on how to remove the gas block from an AR-15

I just installed a set of Yankee hill machine free-float handguards on my ar-15, so I probably should have asked this question before doing it, but here goes anyway.

I heard that you need a special tool/block thingy from brownells to support the gas block when removing the tapered pins. At first I just rested the gas block on a piece of 2x4, and then I put the gas block and barrel in my vice (surrounded by a rag to keep from dinging of course).

Putting it in the vice worked like a charm, I think. My question was; was it a good idea to put the gas block in a vice and then punch the retaining pins out, or do I really need the block thingy from brownells?

I just used a piece of 2x and a punch both in and out. What is most important is driving the taper pins from the correct direction :)

Since you've got the pins out, seems you answered your own question.

The special tools make life easier if you do it a lot, but for a one of they are not cost very cost effective.

A $20 AR multi-wrench is all you really need, maybe a vice if your legs aren't very strong, but I've never had to do anything but clamp the rifle between my knees to torque and un-torque things on an AR. Most free float tubes require replacing the barrel nut and I've never figured out a way to do it without the AR wrench.

you were able to do this job without a vice?

Very interesting, but I think I made the right decision using the vice block from model1sales.

I once tore an AR flattop upper apart trying to loosen a barrel nut.

I didn't have a vice block and didn't think I'd need one just to get the nut off.

$80 mistake and learning experience for me. I've had good luck tapping pins out, provided you do go in the right direction! I have a few different bench blocks made of nylon, steel, and copper to help out. YMMV.

Do yourself a big favor and go to Brownells and get the orange block specifically made for just this purpose. It makes a hard job really simple, but most pins need a really good whack with a big ball peen hammer to loosen them up. Some people put some penetrating oil on and let it sit for awhile, but honestly once you get the block from Brownells I couldn't notice a difference. The block isn't cheap = around $30 = but it's cheaper than busting up a nice barrel. You won't regret having the right tool for the job.
