As many know and complained about, the JSAR comes with a lower PIC rail that also stores magazines. Don't like the storage idea being there and having no where to comfortably grip the rifle ( NO FORE ARM / GRIP ) the lower rail IMO is just shy of worthless.
So taking a block of hardwood, some milling out to fit w/ finger channels on sides, bit of belt sanding, sealing and paint ... We GET a Fore stock of sorts.
Looks worse than it feels, offhand now vastly improved, can be rested now on any surface gaining a lot of stability over resting on the Pic rail.
Clamp on bottle PIC adapter and life is good
