No you don't need to use an ICD ASA, any standard two screw/hole ASA or mount will work. Any of those ASA's would work fine it's really up to you on what looks best and if you want a direct mount or a dovetail. I'd look into the NDZ
, the other CP
, and maybe the Trinitys
. I have the silver Trinity universal one on my borg and it's decent but can sometimes be hard to turn off if your fingers are wet or slick w/ paint.
