The same way you always take them apart.

Start with the BAS, pull the first spring and washer out. Inside the cocking ramp area, move the second spring out of the way, to pull the cocking piece out. Pull the rest of the firing pin out of the bolt.
Compress the Bolt head washer against the bolt body, pop the pin out, then VIOLA! head and baffle come off.
