Cool, I will have to look up that ASA extender.
this particular rail has been milled out big time on the inside. I don't think there is enough meat to put a third hole in the rail for a single screw for an am/mm VA. I will have to check.
I think a spacer may be the easiest, most cost effective way to do this. I just have to find a chunk of aluminum...
So OPBN was right. PPS does have an ASA extender
that would be perfect...and only costs $20!! however the shipping is $16.95!!?? and Taxes haven't been included yet!
