I recently bought a grizzly flattop and wanted to change over my parts from my A2 upper.  the dust cover assembly was easy, but the FA is being stubborn!  What am I doing wrong?  I have tried to drive out the roll pin from both the top and bottom.  All I've succeeded in doing is breaking and bending several punches.

Suggestions anyone?  I'd like to get this done as my barrel is comming back from the machinist (lighter and threaded) and I 'd like to build this baby up in celebration of the sunset.

thanks,

Nevermind,

Got it late last night.  The end of the pin had been belled by the installer.  It created quite the press fit.  

Now my parts are on the Grizzly upper and this A2 is headed to the equiptment exchange.
