How is a gas block removed? Pins go out to left or right?

Pretty sure it does not matter which way you press out the gas block retaining pin,I use a 12 ton press and a small bearing seperator to press off the gas block,you may want to measure the machined surface on your barrel where the gas block sits and the inside of your gas block to be sure you have a good tight fit.................

gas block

Metric barrels do not matter much, but it sure does with inch. The inch pins are tapered, and must install from the left. I have just gotten in a habit of pushing all pins out from the right, and in from the left.

Drive out the pin...if it were tapered, one end would look larger than the other. The metric guns that I've fooled around with didn't care which way the pins went.

Well, now the pin is out, but I've yet to have a gas block just fall off.

The two that I've removed required some heat...the last one required lots of heat and PB Blaster...

But in the end, I was able to drive them loose with a block of wood and a mallet. Resist the urge to grab it with pliers...once you do that, the gas block is all but lost. - Josh M.

Right and left....this is determined by looking down the bore from chamber end correct?

That is how I have always understood it.

Anyway, the Gas Block Pin hole is larger on the left side of an Aussie L1A1, so Adam762's instructions seem valid. He's a pretty savvy FAL type.

While you have to check every pin you're driving out, the traditional gunsmithing way is to drive pins to the right to remove them, and to the left to install them.

That's left and right as you shoulder the rifle, or left and right as you shoot a handgun.

As mentioned above, some pins are different and push out to the left but it's usually easy to spot a tapered pin. A quick measurement with calipers will tell you.

But if it's questionable which way it goes, push out to the right. Most of the time you'll be correct.

I have to ask, why do you want to remove the gas block? It can be a major pain in the ass to remove, and install.

The one time I removed and reinstalled a gas block, I used a 12-ton press to press it off. The barrel rested vertically between some arbor plates with a turned aluminum collar to hold it in position and a brass muzzle protector.

(click for large versions)







To put the gas block back on, I rigged up a nylon collar for the front of the gas block and used a tube that fit over that collar. A threaded rod ran through the bore and was secured against the chamber side using a nylon insert. After adding nuts to both ends, the gas block can be pressed on by just tightening the nuts.

Because I am putting together an Indian....not 100% Indian, clone?.....perhaps Borg?...resistance is futile....

Anyway decent Indian barrels if you can find them, are expensive. Or more likely, expensive sewer pipes.

I have a populated indian gas block and Indian rear sight, so I am planning on using a blued NBC Argy barrel I already have as the donor barrel.

One glitch that may present an issue is that the barrel threads and Indian FH threads are opposite.

Yes....excellent. Clearly driving out the pin and beating on the gas block with a copper mallet ain't gonna git'r dun.
