CZ 805 Bren

[Wilfully_Armed]

Just bought into the wonderful world of CZ Bren with this cool little pinned welded PS1, but I can't seem to find a lot of info on it.

Can anyone tell me what these slots are for?

MLOK slot for whatever? Looks like you can swap it for pic or dickmod if you want too.
