Arm Brace removal

I just purchased my first Kriss in 10mm and the only model available at the time has the factory installed arm brace. I have submitted my ATF form and my intent is to install the folding stock as an SBR once my form comes back. The arm brace attachment appears to be riveted in place. Is this just drilled out and discarded when I go to install the folding stock?

Thanks in advance

You can just drill out the top of the rivet. And I'll actually buy the whole assembly from you.
