I don't own the A&K SR25 but I owned for a while the G&G, and I simply remove the pins to separate the upper from the lower receiver.
As fir the silencer adapter there must be pins in the holes so you can remove it, I guess. It a clone of the G&P SR25 and has the longer V2 gb (V2.5) and also uses SR25 gears, keep that in mind as you a
upgrade it. There's not much support in the SR25 style guns.
I'm currently waiting the G&P XM110 with the standard V2 gb so I won't have much to say to you...
