How do you remove and replace the gas block on a 16" standard barrel?

For what? AK? AR? Mini 14-30?

I'm assuming you have a standard FSP and are talking about an AR.

Drive the 2 pins out toward the eject side. They are tapered. If this is a Stag upper you may have to eyeball it to see what side is tapered...Stag is the only odd ball brand that for whatever reason is sometimes swapped around. *only co. to MY knowledge*

Now that pins are removed. Remove muzzle accessory prior to sliding the FSP off the barrel.

If you are installing the Gas tube into another GB, drive out the roll pin/split pin that holds it in, slide the GT out put it in the new GB and drive the pin back in.


you will need punches....rollpin punches are "cupped' and help out a lot for those FSP pins...


Man I hope you were talking about an AR
