Evening,
I am trying to remove the A2 front sight gas block from my Ranger AR15 upper to fit a low pro and free float handguard.
Has anyone done this?
So far I have measured the pins to see that they are tapered and attempted to drift them out from the smaller side. I have tried heating the block and grinding off the rear of the pins to help.
I am in the process of trying to freeze the upper to shrink the pins.
I have already broken a punch...
Getting frustrated.
Pin "should" just tap out and use a soft mallet to tap off gas block.

I have, but not out of a Ranger AR15. Maybe they put the pins in with more force than the American made ARs? Anyway it took quite a bit of force and I used a ground down nail, ground to the correct diameter.
Will see if the freezer will work, otherwise off to the 'smith
Freezer did nothin...
try using a taper punch to start the pin and go a tiny bit smaller than the pin size I never have any luck using nails for punches
Are you supporting the gas block? You might just have to belt fuck out of it
If you're installing a handguard that fits a standard barrel nut you should just cut down the FSB
I once took the front sight off a RRA barrel, which has straight pins, it was a hell of a mission. Belt the living fuck out of those pins. I'll take the FSB when your done please.
When in doubt, get the big hammer out
that was the plan @gimp but i need to remove the delta ring and handguard plate as I want to put on a free float
yep support the block and belt the %$#@ out of it...
I have only taken one off and a 20 ton press made short work of it-and to my shame I pushed the pins the wrong way!
So I guess I'm in the bash it camp
Will get a bigger hammer....
Am supporting the gas block so no dramas there...
