So I'm looking into getting a free float quad rail. my rig is a PSA Upper and lower with the stainless 16" barrel mid length.

I understand that the front sight will need to come off and the delta ring will get replaced. what i don't understand is what will happen to my gas block. Right know it goes into the standard sight. what will I need to purchase to hold the gas block?  I would like to switch from the 9" fore end to a 12" or 14".

Any info on how to achieve this I would greatly appreciate it. this is my first build.

Cut the FSB down. Paint with high temperature paint.
Cut delta ring off.
Install rail that fits standard barrel nut.

You can keep your FSB, shave it down, or swap to a mini gas block. MI has some rifle length FF quad rails that allow you to keep your FSB. Rail installs very easily and is solid.

Eta; just noticed mid length. I'd shave it as said above or go with a small gas block.

Daniel Defense and just drop it in...but you don't get a longer rail.

Cut down the FSB or install a low pro gas block. As for FF rail brands, I really like the Samson Star-C that came on my Stag. It's only a 9" I believe but Samson makes up to a 15".

Well your not going to need the FSB gas block after your done and you can not reuse it on something else. Unless you don't like the look of the shaved FSB its the route i would go.
