What size pin is the gas block on standard A2 front sight post? I want to change to a gas block with a rail.

Is there anything important about changing gas blocks? Im a newb and would love any info you have

Thanx

Is your front sight still on your rifle? If so, you simply use the original pin in the new gas block. I put one on my 20"er about six mos. ago but I can't remember if it came with a new pin or not. They should tell you when it comes time to order anyway. I believe it is a 1/16" roll pin. Make sure you use/get a set of roll pin drift pins. These are the ones with the little "pimple" on the end to keep them indexed in the center of the roll pin. Good luck! Happy shooting!

"Gas block help."

Sorry, was just gonna tell ya to grab a hold of something and push real hard... once you blow it out you'll feel like a million bucks.

Now I realize you need AR help.

My FSP has caps on each end.

How would I remove it?

I am also looking to install a low pro gas block with a rail over it.

Caps on which ends? And Ends of what?

But to remove it, you just remove the muzzle device, punch the two pins and slide it off (pretty sure there isn't any pinning for the gas tube, but be careful of that).. if you have a hang guard front cup and don't need it, remove that as well. Then slide or mount the new GB, pin or screw it back into place with the gas tube situated correctly, re-attach your muzzle device and go shoot something

Yeah it's a Bushmaster FSP so it doesn't look like a roll pin but rather the pins have kind of rounded caps on each side.

Also what do you guys use to coat the metal under the FSP that is not parkerized?

**mvician** · 11-14-2007, 03:07 PM

the other side should be flat, those are taper pins....hit them HARD, don't be a wuss and end up mushrooming them.

and don't forget the roll pin holding the gas tube in....the hole next to the "crown"

dab a little cold blue on the bare metal

When you get the pins out and your removing your FSB use lots of lube (I use WD40) on your barrel so it wont scratch it as you tap it off.
