Cant post the pics right now, but.
I took a pvs14 j-arm. Measured the pas23 helmet mount I have for one unit. Then cut the j-arm end off, drilled a 1/4" hole at the same distance as the pas23 mount, then dremel cut a inlet/slot for the 23 raised hump to fit in. Used the j-arm screw. And it works fine. When I get back home next day or two, will post pics. Cutting the slot with a dremel was a pita.... an end mill would have done it in 5 minutes or less... but...
It will only work on one side like the original pas23 mount. Wont flip eyes like it does on pvs14.
Easier than finding a pas23 mount on Ebay and paying 150.00 and up for it. Saw one for 200.00 about 8 months back. Saw a pas23 dovetail mount go for 380.00 on ebay.
My $14.00 used j-arm and three hours work, works just fine...
Pics will follow.
Posted them on hide once b4 pte-scout. Cant find the post now. Old pics lost on old dead phone.
